1 Overview

1.1.1 Development Trend of Network Management With the development of IT and IP technology and the convergence of telecommunications, IT, media, and electronic industries, the telecommunications industry has witnessed tremendous growth. The broadband services and mobile services have become the mainstream services in telecommunications networks. All-IP architecture and fixed-mobile convergence (FMC) are the network development goals for the next three to five years, during which the market orientations and business modes of telecom carriers will vary accordingly. The development of all-IP architecture is the leading factor in the transition from the existing vertical network that is divided by technology and service to the flattened horizontal network. Improving user experience, lowering operation expenditure (OPEX), and improving efficiency are the driving forces for FMC. Network convergence requires network management to be consolidated. To be oriented to the future network trend, the iManager U2000 that is the integrated network management system (NMS) combines all-IP and FMC, and manages carrier equipment and access equipment in a centralized manner. The U2000 can perform not only integrated management of multi-domain equipment but also integrated management at the network element (NE) and network layers. The U2000 has revolutionized the layer-based management mode to meet the management requirements in the transition from the existing vertical network to the flattened horizontal network. The integrated NMS U2000 aims to minimize operation and maintenance (O&M) costs for customers and to bring more network value. The U2000 is based on the design of distributed software architecture, and supports the new generation advanced telecom computing architecture (ATCA) hardware platform. In addition, the super network management capability and modular software architecture of the U2000 that shapes the development trend in the future network management make the U2000 a leading all-IP and FMC management solution.

1.1.2 Product Orientation The U2000 is the major and future-oriented network management product and solution in Huawei. The U2000 is an integrated management platform for all equipment in the Huawei. It can manage transport equipment, access equipment, and IP equipment (including routers, security equipment, and Metro Ethernet equipment) in a centralized manner. The U2000 is designed as the management system for Huawei equipment. With powerful management functions at the NE and network layers, the U2000 is the major and future-oriented network management product and solution in Huawei. In the TMN hierarchy, the U2000 is located between the element management layer and network management layer, and supports all functions of the NE and network layers. Figure 1-1 shows the network position of the U2000.

The U2000 supports distributed deployment of the single-server system on SUSE Linux OS. Slave servers can share the CPU usage and memory usage of the master server. In this manner, the load is balanced. 2.1.3 Centralized Deployment of an HA System The U2000 HA system (Veritas hot standby) supports the centralized deployment mode where there is only one server on either the primary site or the secondary site. 2.1.4 Distributed Deployment of an HA System The U2000 HA system (Veritas hot standby) on SUSE Linux OS supports the distributed deployment mode where both the primary and secondary sites use distributed systems.

2.1.1 Centralized Deployment of the Single-Server System The U2000 supports centralized deployment of the single-server system on Windows, Solaris or SUSE Linux OS, that is, there is only one U2000 server on which all management components are installed and all processes run. The U2000 supports a networking scheme of a single server and multiple clients. In the centralized deployment mode of the single-server system, there is only one U2000 server on which all management components are installed and all processes run. See Figure 2-1. Figure 2-1 Single-server mode

This type of networking is applicable to medium and small-scale networks.

Figure 2-2 Distributed deployment mode

The management components for manageable equipment can be deployed on different servers or on the same server. Distributed system consists of the master server and slave server, which compose a site to perform the U2000 server function. The master server is the core of a distributed system. The database server and the core subsystems of the U2000 are running on the master server. The non-core subsystems of the U2000 (such as the management components for manageable equipment) are running on the slave server. In this way, the CPU usage and the memory usage of the master server are lowered, the load is balanced between the master and slave servers and the management capability of the U2000 is increased. In the distributed deployment mode, you can deploy all servers in only the same LAN.

2.1.3 Centralized Deployment of an HA System The U2000 HA system (Veritas hot standby) supports the centralized deployment mode where there is only one server on either the primary site or the secondary site.

The primary and secondary sites comprise an HA system. The data in different locations is backed up through a network. When a fault occurs in the primary site, the system switches to the secondary site so that network monitoring continues. Figure 2-3 shows the networking diagram. Figure 2-3 Centralized deployment of an HA system

2.1.4 Distributed Deployment of an HA System The U2000 HA system (Veritas hot standby) on SUSE Linux OS supports the distributed deployment mode where both the primary and secondary sites use distributed systems. The primary and secondary sites comprise an HA system. The data in different locations is backed up through a network. When a fault occurs in the primary site, the system switches to the secondary site so that network monitoring continues. In the primary or secondary site, master and slave servers are deployed in a distributed mode. The slave servers can share the CPU usage and memory usage of the master server. In this manner, the load is balanced between the master and slave servers. Figure 2-4 shows the networking diagram.

2.2 Networking Scheme Introduction The U2000 adopts the widely used C/S (Client/Server) model. In such a model, the client and the server communicate through the LAN or wide area network (WAN). The U2000 server communicates with its managed devices in inband or outband networking mode. 2.2.1 Inband Networking Mode In inband networking mode, the U2000 uses the service channels that are provided by the managed devices to manage the devices on the network. The messages sent from the U2000 are transmitted through the service channels of the managed devices. 2.2.2 Outband Networking Mode In outband networking mode, the U2000 uses the communication channels that are provided by devices other than the managed devices to transmit messages for network management. In normal cases, the management interface on the main processing unit or routing switch unit of the managed device are used as the access interface.

2.2.1 Inband Networking Mode In inband networking mode, the U2000 uses the service channels that are provided by the managed devices to manage the devices on the network. The messages sent from the U2000 are transmitted through the service channels of the managed devices. Figure 2-5 shows the inband networking diagram.

Managed Network NMS

Networking Description The devices managed by the U2000 are all connected to the managed network. The U2000 needs to be connected to only the nearby NE on the managed network. After configuring the related routes, you can manage all the devices on the network. The way of connecting the U2000 with the managed network depends on the distance between the U2000 and its nearby NE. If the U2000 and its nearby IP devices are in the same equipment room, you can use the LAN mode. If the U2000 and its nearby IP devices are far from each other, you can use the private line mode. The private line mode is similar to the outband networking mode. 

Networking Advantages: This networking mode is flexible and cost-effective. It does not need extra devices.



Networking Disadvantages: In the case of network failure, the communication channel between the U2000 and its managed network is interrupted. As a result, the U2000 cannot maintain the managed network.

2.2.2 Outband Networking Mode In outband networking mode, the U2000 uses the communication channels that are provided by devices other than the managed devices to transmit messages for network management. In normal cases, the management interface on the main processing unit or routing switch unit of the managed device are used as the access interface. In this mode, the U2000 can be connected to the managed devices in multiple ways. The U2000 manages the devices within its management scope through the data communication network (DCN).Figure 2-6 shows the outband networking mode.

Managed Network

Networking description The devices managed by the U2000 are all connected to the managed network. The U2000 connects with the devices on the managed network through the DCN that is made up of other devices. In this manner, the U2000 implements its management on the managed network and devices. 

Networking advantages: In outband networking mode, the U2000 is connected to its managed devices through other devices. It is not connected to its managed devices directly. Compared with the inband networking mode, this mode provides more reliable device management channels. When a fault occurs on a managed device, the U2000 can locate information about the faulty device in a timely manner and monitor this device in real time.



Networking disadvantages: In outband networking mode, the U2000 manages its managed devices through a maintenance channel that is independent of the service channel. To provide such a maintenance channel, you need to build a network that is made up of extra devices. Thus, the cost of constructing the network is high.

Service Deployment Carrying multiple services is one of the most distinctive features of the Metro Ethernet. Services such as the high-speed internet (HSI) service, IPTV, and voice over IP (VoIP) must be established on logical channels. The U2000 allows you to quickly establish specific logical channels on physical networks. For example, you can quickly establish end-to-end MPLS LSP, MPLS TE, PW, and VPLS logical channels through GUIs. You can verify the validity of services before deployment and modify services after the logical channels are established. The Metro Ethernet often carries heavy service traffic. To adapt to this feature, the U2000 provides the batch deployment function to accelerate the deployment process. To ensure the reliability of key channels, you can configure protection protocols such as BFD, VRRP, and MPLS OAM. The U2000 provides efficient test diagnosis tools. Through the related test cases, you can use test diagnosis tools to quickly identify fault causes and rectify network faults, thus ensuring network stability.

Service Assurance The U2000 monitors the running status of the network 24 hours a day and 7 days a week in multiple ways. It can detect network faults or degradation in a timely manner and report endto- end SLA data of the network. The U2000 provides the following service assurance for the broadband bearer network: 

Real-time alarm monitoring and notification The U2000 can monitor network faults and the status of devices and interfaces in real time. By notifying the related personnel of network faults through the SMS or email, the U2000 effectively ensures the normal running of the network.



Performance monitoring 24 hours a day and 7 days a week The U2000 regularly collects the traffic data of all the links or some key links on the entire network to provide effective support for network monitoring.



4 NMS Basic Functions 

The U2000 can automatically detect and clear invalid sessions.

User and User Group Management The functions of user and user group management are described as follows: 

Creating a user account or user group. During user account creation, the user details, owner group of the user, management domain, user permissions, and access control list must be set. During user group creation, the user group details, management domain, and user group permissions must be set.



Modifying the user or user group information, and deleting a user account or user group.



Adding a user to a user group. After addition, the user has the permissions of the user group. A user can be added to multiple user groups. In this case, the user has the permissions of the user groups besides those of the user.

Permission Management User permissions are classified into management permissions and operation permissions. Through permission assignment, user operations on the U2000 can be controlled. 

Management permissions refer to the permissions that a user is given to manage the specified equipment and its data, or the permissions that a user group is given to manage the specified domains. In the topology view, the equipment or areas that cannot be managed are invisible.



Operation permissions refer to the permissions that a user is given to perform operations. If a user does not have the permissions to manage a type of equipment, the user does not have the permissions to operate the equipment.

The functions of permission management are described as follows: 

Adding or deleting user or user group permissions, and setting the management domain of the user or user group.



Creating object sets. Managed objects are grouped into different object sets to facilitate permission assignment.



Creating operation sets. Operation permissions are grouped into different operation sets to facilitate permission assignment.





Assigning the permissions of a type set to the user. After that, the user has the permissions to view and operate the devices whose type is consistent with the type set.

Security Policy Management The functions of security policy management are described as follows:

4-4



The password policy is used to set the user password rules and password security policies. The password rules involve the minimum password length of common users, minimum password length of superusers, and maximum password length. The password security policies involve the maximum number of password duplications with history passwords, maximum password reservation period, minimum password reservation period, and number of days ahead for notifying password expiration.



The account policy is used to set the minimum length of the user name, automatic unlocking time, maximum number of login attempts, and timeout period at a login or unlocking failure.


Issue 03 (2010-11-02)



Access Control List The Access Control List (ACL) is a secure access control mechanism. It restricts user access to the server by allowing only the clients with specified IP addresses. ACL can effectively control the client IP addresses from which users can log in to the U2000. In this case, even if the user account and password are obtained by illegal users, these users cannot log in to the U2000. Thus, the security of the U2000 is improved.

4.2 Topology Management In topology management, the managed NEs and their connections are displayed in a topology view. The managed NEs are displayed and managed in subnets and views. You can monitor the operating status of the entire network in real time by browsing the topology view. U2000 provides the Physical Root, Clock View, IP View, Tunnel View, and Custom View. Therefore, you can view the required information in different views and also monitor and learn the operating status of the entire network.

Topology View and Its Functions The topology view of the U2000 consists of a navigation tree on the left and a view on the right. The navigation tree directly shows the network hierarchy. Meanwhile, the view displays the objects at different coordinates in the background map, which offers an intuitive view on the deployment of objects. Figure 4-3 shows the functions provided in the topology view of the U2000. Figure 4-3 Topology view and its functions

Alarm Display In the Topology View In the topology view of the U2000, alarms are displayed in different colors to indicate different status of the submaps and NEs. The alarms in the topology view are displayed by two methods: color-coded display and small icon display. The default method is the small icon display, as shown in Figure 4-4. Figure 4-4 Alarm display in the topology view

The display of topology alarms on the U2000 has the following features: 

The color of a topological node indicates the polling status (such as normal, unknown, or offline) and the alarm status of the monitored NE.



When an NE generates multiple fault alarms at different severities, the corresponding topological node is displayed in the color/iron that indicates the highest alarm severity of these alarms.



When multiple nodes in a subnet generate fault alarms, the subnet is displayed in the color/iron that indicates the highest alarm severity of these alarms.



You can query the current alarms of an NE through the NE node. In addition, you can query the details of the fault alarms through the NE Panel.

Automatic Topology Discovery The U2000 provides the automatic topology discovery function. Therefore, manual intervention is not required and the operational expenditure (OPEX) is reduced. The U2000 supports two methods of automatic topology discovery, as follows: 

4-6

After the SNMP parameters are set on the NE based on the SNMP protocol, the NE sends traps to the U2000 in an unsolicited manner. Then, the NE is added to the topology view on the U2000 automatically. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

Issue 03 (2010-11-02)





In automatic topology discovery, the transport NE, NE based on the SNMP protocol, and NE based on the ICMP protocol are searched separately in batches. Then, the NE that is searched out is added to the topology view automatically.



The Secuity NE can be added to the topology view automatically by use the function of Batch Import NE.



The U2000 searches for the fiber/link in batches. Then, the discovered fiber/link is added to the topology view on the U2000 automatically.

Figure 4-5 Illustration of automatic topology discovery

1.

The automatic topology discovery operation is implemented step by step through a wizard. Specifically, the wizard guides you to configure the parameters required for the automatic discovery, such as NE type, SNMP parameters, and the IP address range.

2.

After you finish configuring the parameters, the U2000 searches for the required NE among the specified network segments according to the preset parameters. All NE (both from Huawei and other vendors) that is based on the SNMP protocol and meets the conditions is displayed automatically in the topology view. At the same time, the basic configurations of the NE is uploaded automatically. In this manner, you need not perform basic configurations on the NE again.

3.

During the discovery, you can cancel the discovery at any time. In addition, you can learn the cause if the discovery fails.

4.3 Alarm Management In alarm management, you can monitor network exceptions in real time. It provides various management methods such as alarm statistics, alarm identification, alarm notification, alarm redefinition, and alarm correlation analysis. This helps the network administrator take proper measures to recover the normal operation of the network.

Networkwide Alarm Browsing Alarm display is classified into alarm panel display, alarm topology display, and alarm browsing. The U2000 supports the following alarm browsing functions:

Function

Description

Sequence customizing

Through the sequence customizing function, you can sort alarms by field in the alarm list and customize the alarm display. In addition, you can save alarms in the .txt, html, xls, pdf, and csv file, and print the required alarm records.

Alarm Statistics You can learn the alarm status through alarm statistics and alarm analysis. U2000 can collect alarm statistics based on user-defined conditions. The alarm conditions include the alarm name, alarm severity, alarm function type, alarm rising time, alarm status, or a combination of any preceding items.

Alarm Masking and Alarm Correlation Analysis NEs report a large number of alarms during maintenance, test, or new deployment. However, you need not concern the reported alarms. Therefore, these alarms reported by the NE need to be masked, that is, these alarms are not displayed or saved. You can set conditions to mask the alarms or events that meet the conditions. The U2000 provides the following means for you to perform specific correlation analysis: alarm/event correlation analysis, intermittent alarm analysis, repeated event analysis, and alarm/event frequency analysis, and lasting time analysis of acknowledged but uncleared alarms.



Alarm/Event correlation analysis This function helps to find the root alarm. The U2000 supports the analysis of the correlation between different NEs. The system analyzes the alarms based on the pre-defined correlation rule to mask the correlative alarms and finds the root alarm. This helps the maintenance personnel to easily find and rectify the fault.



Intermittent alarm/repeated event analysis This function helps you to analyze alarms that are repeatedly cleared or events that are repeatedly reported within a short period of time. To handle these alarms or events, the system reserves only one of these alarms or events and/or change their severities. The reserved alarms or events record the frequency with which the intermittent alarms or

4-10


Issue 03 (2010-11-02)



repeated events occur. In addition, the system can change the alarm or event severity according to the pre-defined settings. 

Alarm/Event frequency analysis This function helps you to analyze the frequency with which an alarm or event occurs. You can set a condition. Within the pre-defined period, when the number of alarms or events exceeds the threshold, the system informs the user according to the pre-defined correlation action.



Acknowledged&Uncleared alarm time analysis This function helps you to analyze the time of an acknowledged but uncleared alarm. You can set a condition. Within the pre-defined period, if the time of an acknowledged alarm exceeds the threshold, the system changes the alarm severity.

Alarm Dumping and Acknowledging Alarm acknowledgment helps to identify whether an alarm is processed. Alarm acknowledgment helps you to identify a processed alarm. You can then take proper measures by checking whether the alarm is in the acknowledged state. 

Alarm dumping: It supports overflow dumping and manual dumping of alarms. Alarm dumping is used to dump history alarms and events to files, which ensures a stable and efficient system and saves disk space.



Alarm acknowledgment: It helps you to identify a processed alarm. You can then take proper measures by checking whether the alarm is in the acknowledged state. The U2000 supports manual and automatic acknowledgment of alarms.

Alarm Synchronization The U2000 supports the ability to synchronize NE alarms automatically and manually. You can manually synchronize NE alarms by performing operations through GUI or set an automatic synchronization policy. When the U2000 restarts or the communication with an NE recovers, the NE sends an alarm to the U2000. This implements the automatic alarm synchronization on the U2000. The U2000 supports the ability to synchronize NE alarm. 

Manual synchronization You can manually synchronize NE alarms by performing operations through GUI.



Automatic synchronization You can set an automatic synchronization policy. When the U2000 starts, when its communication with an NE recovers, or when the LCT user logs out, the NE sends an alarm to the U2000. This implements the automatic alarm synchronization on the U2000.

Alarms are synchronized according to the following rules: 

If an alarm is cleared on the NE but uncleared on the U2000, the alarm on the U2000 is cleared.



If an alarm exists on the NE but does not exist on the U2000, the alarm is added to the U2000.

Alarm Redefinition The U2000 allows you to redefine the alarms of the NE. You can redefine the alarm severity according to the requirements. You can use this function to change the alarm severity displayed on the U2000, thus highlighting only the alarms that concerns you.

Alarm Suppression U2000 supports the ability to suppress NE alarms. If you set the status of an alarm to Suppressed, the NE does not report the alarm. The difference between alarm suppression and alarm masking is as follows: If you enable alarm masking, an NE still reports an alarm but the U2000 does not receive the alarm. If you enable alarm suppression, the NE does not report an alarm.

Various Alarm Notification Means The U2000 provides various alarm notification means. The U2000 can send notifications to the related maintenance personnel for locating faults regardless of the time and place, which ensures that the faults are troubleshoot in time. Figure 4-7 shows the alarm notification means.

4-12


Issue 03 (2010-11-02)

Issue 03 (2010-11-02)



Alarm Time Localization U2000 can display the time when an alarm is generated, acknowledged, cleared, or received as the local time. The U2000 can display the time based on the server time or client time. The NE that reports an alarm and the current U2000, however, may be in different time zones. To learn the correct alarm generation time, the U2000 automatically converts the alarm generation time (NE time) into the local time of the client.

4.4 Performance Management The U2000 can monitor the key indicators of a network in real time, and provide statistics on the collected performance data. It provides a graphical user interface (GUI) to facilitate network performance management. Figure 4-9 Performance Management Process

5 MSTP Network Feature Management

MSTP Network Feature Management

About This Chapter This topic describes the functional features of MSTP NE management and network management. 5.1 MSTP NE Management NE management refers to the management of configurations of an NE in terms of attributes, communication, services, protection, and clocks. The configuration data is saved to the database of the U2000 and to the database of the NE. 5.2 MSTP Protection Subnet Management A protection subnet is a network structure with the comprehensive self-protection function. In the U2000, the protection subnet is a generalized concept that includes not only the network structure with the comprehensive self-protection function, such as an MSP ring and a path protection (PP) ring, but also the network structure without the self-protection function, such as an unprotected ring and an unprotected chain. 5.3 End-to-End MSTP Management End-to-end network management is also referred to as trail management. You can construct the configuration data of end-to-end network management by searching for the data at the NE layer of the U2000, or directly configure the data at the network layer of the U2000, and apply the data to all the related NEs. Compared with configuring NE data on a per-NE basis, configuring NE data by using the trail management function is faster and more convenient. 5.4 End-to-End MSTP IP Management There is the IP feature in MSTP equipment. You can build the configuration data of end-to-end MSTP IP network management by searching for the data at the NE layer of the U2000, or directly configure the data at the network layer of the U2000, and apply the data to all the relevant NEs. Configuring NE data by using the trail management function is faster and more convenient compared with configuring NE data on a per-NE basis. 5.5 SDH ASON Management ASON is a new generation of optical network that integrates the exchange and transport. After a user initiates a service request, the ASON selects a route automatically, establishes and removes connections through the signaling control, and performs network connections automatically and dynamically. An ASON NE refers to the equipment that is equipped with

5-9



−

dual node interconnection (DNI) protection.

−

Non-protection (NP) ring and NP chain.



Search for a protection subnet according to the information of NEs and fibers or cables in the U2000, to form a complete protection subnet.



Migrate an NP chain to a 1+1 linear MSP without interrupting services.



Start or stop the MSP protocol of the MSP subnet, such as enabling or disabling the MSP protocols networkwide or the MSP protocol for a single node.

6 WDM Network Feature Management

WDM Network Feature Management

About This Chapter This topic describes the functional features of WDM NE management and network management. 6.1 WDM NE Management NE management refers to the management of configurations of an NE in terms of attributes, services, protection, and clocks. The configuration object is a single NE. The data is saved to the database of the U2000 and the database of the NE. 6.2 NA WDM NE Management NE management includes the configurations on attributes, communications, services, protection, and clock on an individual NE basis. The configuration data is saved at the NE layer on the U2000 and in the database of the NE. 6.3 WDM Protection Subnet Management A protection subnet is a network structure with the comprehensive self-protection function. In the U2000, the protection subnet is a generalized concept that includes not only the network structure with the comprehensive self-protection function, such as an MSP ring and a PP ring, but also the network structure without the self-protection function, such as an unprotected ring and an unprotected chain. 6.4 End-to-End WDM Management End-to-end network management is also referred to as trail management. You can construct the configuration data of end-to-end network management by searching for the data at the NE layer of the U2000, or directly configure the data at the network layer of the U2000, and apply the data to all the related NEs. Compared with configuring NE data on a per-NE basis, configuring NE data by using the trail management function is faster and more convenient. 6.5 WDM ASON Management ASON is a new generation of optical network that integrates the exchange and transport. After the user initiates a service request, the ASON selects a route automatically, establishes and removes connections through the signaling control, and performs network connections automatically and dynamically. An ASON NE refers to the equipment that is equipped with both WDM and ASON features. An ASON network is managed by the U2000 that combines ASON and WDM features.

Optical Power Adjustment By using the U2000, a user can perform the following operations: 

Manage the optical power. The user can query the input power, output power and power threshold and so on for each WDM board.



Perform the function of intelligent power adjustment (IPA) management. When a fiber is cut off, the optical amplifier board detects the signal loss at the station. The station reports an exceptional event to the U2000. After the user confirms the event, the optical amplifier boards at the upstream and downstream stations reduce their output power to a safe value to prevent the fiber maintainer from being hurt by the lasers emitted from the cut-off fiber. After the fiber is reconnected, the optical signals restore to normal and the optical power of each optical amplifier board automatically returns to a normal value.



Automatic level control (ALC) management: Support the adjustment modes including wavelength count detection, power detection, and link attenuation (gain mode). The wavelength detection mode applies to the transmission link where no service is added or dropped or where the number of wavelengths added and that dropped are the same at the OADM. When the spectrum analyzer unit detects that the sum of each wavelength power greatly differs from the standard power of the corresponding wavelength count, an exceptional event is reported to the U2000. After the user confirms the event, the user needs to manually issue a command to adjust the attenuations of each station on the link. The power reference mode applies to the transmission links where the number of added wavelengths differs from the number of dropped ones at an OADM. When the optical amplifier board detects that the output power becomes abnormal, the station automatically issues the command to adjust the attenuation of each station on the link. This mode does not involve the spectrum analyzer unit, and is thus cost-effective. For the previous two modes, a user can manually control whether to enable the ALC function. The link attenuation adjustment mode also applies to the transmission link where the number of added wavelengths differs from the number of dropped ones at an OADM. When the optical power is attenuated to the detection threshold, a command is automatically issued to adjust the attenuation of each station on the link. The link attenuation adjustment mode is also referred to as the gain mode, which compares the difference between the line attenuation and the amplifier gain, and also compares the node gain compensation offset. Through the adjustment of the nominal gain of the optical amplifier unit and the attenuation value of the attenuation adjustment unit, the attenuation value is equal to the gain value, thus ensuring the power budget of the entire link.



Perform the function of automatic power equilibrium (APE). If the MCA board at the receive end detects that the optical power of some channels is abnormal, the station reports an exceptional event to the U2000. After the user confirms the event, the U2000 issues a command to the optical attenuation adjustment board of the upstream station. This board adjusts the optical power of the abnormal channel so that the optical signal noise ratio (OSNR) of each channel at the receive end is equalized.



Perform the function of ROADM optical power equalization. After the ROADM is used to dynamically configure the wavelength services, the WDM equipment outputs multiplexed wavelengths. The optical power, however, may be greatly different between each channel, especially for the newly added wavelength channels. To avoid negative impacts on the transmission performance, the ROADM optical power equalization function is provided. The ROADM first distinguishes between the pass-through wavelengths and the added wavelengths. Then the DWC/WSS adjusts the optical power of the pass-through wavelengths, and the optical attenuation adjustment board adjusts the added wavelengths based on the wavelength flags.

Optical Power Adjustment By using the U2000, a user can perform the following operations: 

Manage the optical power, such as querying the input power, output power, and power threshold for each WDM board.



Perform the function of IPA management. When a fiber is cut off, the optical amplifier board detects the signal loss at the station. The station reports an exceptional event to the U2000. After the user confirms the event, the optical amplifier boards at the upstream and downstream stations reduce their output power to a safe value to prevent the fiber maintainer from being hurt by the lasers emitted from the cut-off fiber. After the fiber is reconnected, the optical signals restore to normal and the optical power of each optical amplifier board automatically returns to a normal value.



ALC management: Support link attenuation (gain mode) as the adjustment mode. The link attenuation adjustment mode applies to the transmission link where the number of added wavelengths differs from the number of dropped ones at an OADM. When the optical power is attenuated to the detection threshold, a command is automatically issued to adjust the attenuation of each station on the link. The link attenuation adjustment mode is also referred to as the gain mode, which compares the difference between the line attenuation and the amplifier gain, and also compares the node gain compensation offset. Through the adjustment of the nominal gain of the optical amplifier unit and the attenuation value of the attenuation adjustment unit, the attenuation value is equal to the gain value, thus ensuring the power budget of the entire link.



Perform the function of APE. If the MCA board at the receive end detects that the optical power of some channels is abnormal, the station reports an exceptional event to the U2000. After the user confirms the event, the U2000 issues a command to the optical attenuation adjustment board of the upstream station. This board adjusts the optical power of the abnormal channel so that the OSNR of each channel at the receive end is equalized.



Perform the function of ROADM optical power equalization. After the ROADM is used to dynamically configure the wavelength services, the WDM equipment outputs multiplexed wavelengths. The optical power, however, may be greatly different between each channel, especially for the newly added wavelength channels. To avoid negative impacts on the transmission performance, the ROADM optical power equalization function is provided. The ROADM first distinguishes between the pass-through wavelengths and the added wavelengths. Then the DWC/WSS adjusts the optical power of the pass-through wavelengths, and the optical attenuation adjustment board adjusts the added wavelengths based on the wavelength flags.




Dispersion Compensation 

The G.652 and G.655 fibers have positive dispersion coefficient and positive dispersion slope at 1550 nm window. After the optical signal is transmitted over a certain distance, the accumulation of positive dispersion broadens the optical signal pulse and seriously affects the system transmission performance. To minimize this effect, a negative DCM is used in the network. It uses negative dispersion to compensate the positive dispersion of transmitting fiber, so as to maintain the original shape of the signal pulse.



The OEQ NE can apply dispersion compensation to each band to reach dispersion equalization.

packet from the opposite end in a specific time, the system regards that a failure occurs in some part of the bidirectional channel to the adjacent system.

QoS Configuration Quality of service (QoS) indicates the performance of the data flow that travels through a network. The QoS is used to ensure end-to-end service quality. The QoS cannot increase the bandwidth, but it can minimize the delay and jitter in the network by reasonably allocating and monitoring network resources. In this way, the quality of important services is ensured. The DiffServ (DS) domain consists of a group of network nodes that enable the DiffServ function, that is, DS nodes. In a DS domain, all DS nodes use the same service provision policy to realize the same per-hop behavior (PHB). The DS nodes are classified into edge DS nodes and internal DS nodes. The edge DS nodes usually perform complex flow classification on the traffic that enters the DS domain. Traffic of different types is marked with different PHB service types. For internal DS nodes, you need to perform only simple flow classification based on PHB service type. The U2000 supports the following QoS functions: 



Configure quick leave ports.



Manage routes.





Query statistic information of IGMP protocol packets.

BFD Configuration Bidirectional forwarding detection (BFD) can be used to check the Ethernet link status. BFD is a simple Hello protocol. It is similar to the neighbor check of those famous protocols in many aspects. A pair of systems periodically sends detection packets on the channel on which session between the two systems is created. If a system does not receive any detection packet from the opposite end in a specific time, the system regards that a failure occurs in some part of the bidirectional channel to the adjacent system. The U2000 supports the functions of performing the BFD detection on IP/GRE tunnels and the inter gateway protocol (IGP). The U2000 supports configuring single-hop or multi-hop BFD detection.

LPT Configuration LPT is used to return the remote-end link status to the near end. The near-end equipment performs operations depending on the remote-end link status. When the intermediate transmission network of the services becomes faulty, the LPT informs the access equipment at both ends of the transmission network to enable the backup network. That ensures the normal transmission of the important data.

Synchronization Protocol Configuration In the application scenario of dual-homing, the status of the peer equipment needs to be obtained either for the MC LAG or for the cross-MC LMSP. Meanwhile, the actions on both sides need to be negotiated based on different fault cases. With the method of adding information of the peer end, a channel is established for control status synchronization with the peer end. In this manner, the control packets can be transmitted and received through the channel and link fault detection can be performed.

LMSP/MC LMSP Configuration Linear MSP protection contains 1+1 linear MSP and 1:N linear MSP. They use the protection channel to protect services that are transmitted on the working channel. When the working channel fails, services are switched to the protection channel. The linear MSP applies to the POS interface and structured STM interface. The multi-chassis (MC) LMSP can implement the LMSP among NEs. The U2000 supports the following functions of LMSP/MC LMSP configuration:

E-Aggr Service Configuration The E-Aggr service is a multipoint-to-point Ethernet service. The equipment uses several ports to access services from the V-UNI side, and converges the services into one PW at the network side for transmission. In this way, user data from multiple points can be converged into one point. See Figure 8-5 and Figure 8-6. One carrier wants to construct a 3G network. Services of each Node B are converged and transported to the RNC. The data between each Node B and RNC is regarded as one service. At the convergence point, the QoS parameters such as the overall bandwidth are specified.

E-LAN Service Configuration The E-LAN is a multipoint-to-multipoint Ethernet service. It connects to multiple V-UNI and NNI access points. It realizes packet forwarding and interconnection by using the MAC address self-learning scheme of layer 2. See Figure 8-7. The HQ of Company A is in City 3. Company A has Branch A in City 1, City 2, and City 3, and has Branch B in City 1 and City 2. Branch A and Branch B do not have business with each other. Hence, the data should be isolated between the two branches. The HQ has requirements of communicating with each branch and accessing the Internet. Figure 8-7 E-LAN service

Different VLANs are used to identify service data of different branches by using the E-LAN service. In this way, data is shared within a branch and is isolated from other branches. The Internet data of the HQ is also isolated from the internal service data by using the VLAN. The U2000 supports the following functions of configuring E-LAN services on a per-NE basis:

Issue 03 (2010-11-02)


9-9



A template has the following features: 

Offline configuration Global templates are created in advance and saved on the U2000 instead of being created on a device. Thus, you can create global templates when devices are offline or do not exist. The creation of global templates is irrelevant to the device status.



Global validity After a global template is created, this template can take effect on all the devices managed by the U2000. It can be referenced by a type of device or none of the devices.





Little duplicate data −

After a global template is applied to a type of device, if the template data on some devices is the same, the U2000 keeps only one template data record for these devices.

−

When a device references a global template, the U2000 does not adds a record of template data. Instead, the U2000 records the reference relation between the device and global template.

A global template can be referenced by a large number of devices of the same type, which helps to reduce recorded template data and facilitate maintenance.

Main Templates The main templtes are as follows: 

ACL template ACLs can be used to control the access of user packets that flow into ports. Configuring ACLs in batches simplifies the configuration of the defense against attacks on the network access side. When you configure the firewall on the network access side, you need to configure ACL matching rules, such as the restriction on a MAC address and the restriction on an IP address. If a rule needs to be applied to multiple interfaces on different routers, configuring the rule at every point is time-consuming and increases the costs of management and maintenance.



QoS template The main applications of network QoS are as follows:



−

CBQoS template, and it can be applied to interfaces on NEs in batches.

−

DS domain template, and it can be applied to interfaces on NEs in batches.

−

HQoS template, and it can be applied to interfaces on NEs in batches.

−

PQ template, and it can be applied to interfaces on NEs in batches.

−

Interface CAR template, and it can be applied to interfaces on NEs in batches.

VPN service template The service template is used to perform batch configurations for multiple devices when a VPN service is created or configured. In this manner, the efficiency of service deployment is greatly improved.



Switch EPON template When you configure multiple ONU services, you can manage ONUs uniformly by configuring templates to improve configuration efficiency.



The U2000 provides intelligent result analysis. You can manually customize the thresholds of test case indicators such as delay, jitter, and packet loss ratio in the result analysis template and the result analysis policy according to the related service level. In this manner, you can quickly determine the network status.

Test Diagnosis Management Through test diagnosis management, you can test the connectivity and QoS of a network and diagnose network faults according to the test results. Test diagnosis management helps to narrow the range of fault diagnosis and reduce the time of fault location and rectification. A test diagnosis tool consists of the following parts: 



Issue 03 (2010-11-02)

Test suite −

A test suite is made up of multiple test cases. Created according to user test requests, a test case is the entity of a test tool based on the application layer, transport layer, network layer, data link layer, and MPLS services. The test suite is a group of test tools organized according to certain test scenarios.

−

You can take a test suite as a performance unit and perform all the test cases or optionally perform some test cases in the test suite. Then you can diagnose network QoS according to the parameters shown in the test results, such as delay, jitter, and packet loss ratio.

Diagnosis policy


9-11



The U2000 provides multiple running policies for test suites. You can run the test suite associated with a certain running policy at a specified time daily, weekly, or monthly. 

Network scanning It collects network information through network synchronization and tests the connectivity of partial types links on the network. The U2000 provides real-time scanning and allows you to stop running scanning tasks. The U2000 also provides the traceroute function for you to locate faults.



History data The history data is the records of test suite operations. You can filter and query history data according to conditions such as the test suite name, test result, or test time, and export query results.



Diagnosis result analysis It provides intelligent result analysis. You can manually customize the thresholds of test case indicators such as delay, jitter, and packet loss ratio in the result analysis template and the result analysis policy according to the related service level. In this manner, you can quickly determine the network status.

10.3 Centralized Security Policy Configuration Deploying a set of security devices with comprehensive technologies during network security construction does not mean that the network is under stable and reliable security protection. In network security maintenance, even deploying a satisfied security policy scheme for a small-sized local network is a rather complex task. Designing and deploying a set of reliable security protection policies for a large-scale network, accordingly, is a fairly hard and challenging task. An industry-leading security policy design, configuration, and management system is worked out upon the aim of making a security configuration and management center. With this system, the truly reliable and stable network security protection can be implemented on the basis of the security devices deployed on the network. It has the following features: 

Policy package management A policy package can be used to manage all the security devices on the whole network and sort the protection tasks on each security device into security policy, attack defense, and service port mapping. Users can create their own policy packages and include the configuration tasks in the policy packages. Users can also perform operations such as creating, deploying, undeploying, and verifying policy packages. A policy package can cover all the network security configuration and management tasks of a user on a network.



Configuration and management ranges Security policy Attack defense Service port mapping Policy resource



Policy recovery During network security management and maintenance, how to ensure the data consistency between the NMS and devices so that the actual network configurations can be accurately displayed on the NMS? Policy recovery can restore the security policies and attack defense configurations deployed on devices and the used resources of devices to the NMS, thereby achieving the data consistency between the NMS and devices.



Policy audit Auditing the configuration data difference between the NMS and devices helps to ensure the data consistency and make users to fully trust the NMS when using it.



Security policy configuration and management modes of two dimensions

1.

Service-dimension configuration: manages the configurations when the services are deployed on multiple or all devices on the network. This helps users to manage and audit services from the point of networkwide view. On a large-scale network, users do not need to check and configure services on devices one by one. Therefore, missing configurations are reduced, and security services can be configured reliably and efficiently.

Issue 03 (2010-11-02)


10-3



2.

Single NE-dimension configuration: manages the configurations of a single NE. Users can select an NE to check security configurations, create, modify, deploy, and undeploy configurations, and import the configurations of other NEs to this NE.



Policy deployment status display Whether a policy is deployed, whether the deployment is successful, and whether the deployment status is the same as that on the device are displayed. This helps to prevent the repeated deployment of a policy that is already deployed.



History record query The detailed policy package configuration and maintenance procedures are recorded. The history operations that users perform on policy packages can be audited.

By changing operations based on single policies and single devices to centralized operations based on batch policies and multiple devices, this feature increases operation efficiency and reduces maintenance cost. The policy packages verifying function ensures the correctness of policy package configurations and correlations among the policies within the same policy package. With the policy verifying function, you can correctly deploy policy packages on devices and avoid repeated modifications due to configuration errors during policy deployment. Policy auditing is to audit the policy configuration differences between the NMS and device, so as to determine whether the policy needs to be deployed or discovered. Policy discovery is to recover the data synchronized to the database to the NMS for management. The rights to perform various operations on policy packages are under control. Operations on policy packages are recorded in logs for the policy maintenance personnel to monitor and manage policies.

ONT Management

The U2000 supports the management of EPON terminals in the OAM mode and GPON terminals in the OMCI mode. In this manner, the terminals are managed in a centralized manner, which saves the maintenance workload. To manage xPON terminals, the U2000 adopts two solutions, namely, SNMP+OMCI and FTP+OMCI. 

The objects managed by the ONT L2 protocol and protocols at lower layers provision multicast IPTV and data services by using the SNMP+OMCI solution.



The VoIP services are provisioned through the FTP+OMCI solution. The N2000 BMS generates a .xml configuration file and then uploads the file to the FTP server. The OLT obtains the configuration file from the FTP server, loads it, and then sends it to the ONT through the OMCI. Finally, the service configuration of the ONT is complete.

The U2000 supports the automatic batch upgrade of ONTs. 

15.2 HA System The high availability (HA) system helps you improve the running reliability of the U2000 server. The non-distributed U2000 server uses a 1+1 scheme. If the active site fails, the U2000 can be switched to the standby site so that the U2000 application is not interrupted.

The U2000 supports distributed cluster. For better stability and risk resistance capability, the distributed cluster uses a 1+1 scheme. If a slave server fails, the master server fails, the

database is faulty, IP addresses conflict, or the key process fails to be switched, you can switch the distributed cluster to the standby distributed cluster without interrupting the U2000. The protection mechanism of an HA system has two aspects: 

Database synchronization and backup between the active and standby sites



Switching the application program between the active and standby sites

The U2000 provides the following HA schemes: 

HA system (Veritas 1+1 hot standby): Applicable to remote hot standby of the non-distributed system, featuring automatic switching.



HA system (Veritas distributed hot standby): Applicable to remote hot standby of the distributed system on SUSE Linux OS, featuring automatic switching.

15.3 DCN Protection You can use a data communication network (DCN) to connect the U2000 to a standby gateway NE (GNE). This improves the reliability of the communication connection between the U2000 and equipment. The communication between non-GNEs and the U2000 is forwarded by the GNE. In the U2000, you can set the active GNE and standby GNE for NEs in advance. When the communication between the active GNE and the U2000 is interrupted, the U2000 automatically switches to the standby GNE for communication, so that the communication between the U2000 and NEs is not interrupted. When the communication between the U2000 and the active GNE recovers, the U2000 determines whether to use the active GNE again according to the preset revertive mode.

15.4 Disk Mirroring The disk mirroring function helps you improve the reliability of disk data on the U2000 server. If the server is a Sun workstation with more than two hard disks, disk mirroring can be installed together with the U2000. After you create disk mirroring, if the active disk fails, you can use a command to switch the data to the standby disk, to restore the working data and parameter settings before the active disk is damaged.

15.5 Data Backup The data backup function helps you improve the reliability of important U2000 data. The security of network data is a concern for users. The U2000 provides the following solutions listed in Table 15-2.

17 Management Capability

Management Capability

About This Chapter Introduce the manageable equipment and the management capability of the U2000. 17.1 Management Capability The management capability of the U2000, on the basis of satisfying the preceding performance indexes, can be measured by the maximum number of NEs it manages.

17.1 Management Capability The management capability of the U2000, on the basis of satisfying the preceding performance indexes, can be measured by the maximum number of NEs it manages. Currently, a set of U2000 can manage a maximum of 15,000 physical NEs, 20,000 equivalent NEs and 100 clients. This conclusion is drawn after the tests under a certain environment and objectively reflects the actual management capability of the U2000. 

Management capability: In this document, management capability refers to the capability of the NMS to manage network resources, which are expressed in the number of equivalent NEs.



Equivalent NE: The functional features, cross-connect capacity, and number of boards/ports/channels are specific to NEs of different types. As these NEs require different resources of the NMS, the number of NEs that can be managed by the NMS depends on the NE types. For easy description and calculation of the management capability, the concept of equivalent NE is defined so that NEs of different types or a number of ports can be converted to equivalent NEs by an uniform criteria according to the system resources required by them. The system resources required by an equivalent NE is equal to the resources for managing an STM-1 transport NE.



Equivalent coefficient: The equivalent coefficient refers to the ratio of the resources used by physical NEs or ports to the resources used by equivalent NEs. Equivalent coefficient = (Resources used by physical NEs or ports)/(Resources used by equivalent NEs)

The management capability of the U2000 in a network that consists of different types of NEs is affected by the following factors: 

Issue 03 (2010-11-02)

The key technical specifications include the number of equivalent NEs, number of clients, and number of physical NEs.


17-1





The management capability of the U2000 also depends on the hardware and varies with the hardware configuration.



The system limits the number of physical nodes. Hence, the number of physical nodes is a restriction for the management capability.



The management capability refers to the maximum number of equivalent NEs that can be managed by the U2000 on certain hardware configuration conditions.



If a client also runs on the computer where the server is running, the management capability is reduced by 50%. Hence, it is recommended that you run the client and server on different computers.



Virtual NEs are not included in the management capability. A pre-configured NE is equal to a real NE. One third-party NE is equal to one equivalent NE, and can only be discovered instead of being managed. The equivalent coefficient of the OEM equipment is calculated in the way similar to Huawei equipment.

Generally, the number of equivalent NEs that the U2000 can manage is calculated according to the following rules: 

Number of equivalent NEs = + +



= (Number of transport NEs of type_I x Equivalent coefficient + ... + (Number of transport NEs of type_n x Equivalent coefficient) For example, there are 5 OptiX OSN 9500 (equivalent coefficient: 10), 10 OptiX OSN 7500 (equivalent coefficient: 6.5), and 100 OptiX OSN 3500 (equivalent coefficient: 4.5). Then, you can calculate the number of equivalent NEs in the transport domain as follows: Number of equivalent NEs in the transport domain = 5 x 10 + 10 x 6.5 + 100 x 4.5 = 565



= (Number of IP NEs of type_I x Equivalent coefficient) + ... + (Number of IP NEs of type_n x Equivalent coefficient) For example, there are 5 NE5000E (equivalent coefficient: 10), 200 S5300 (equivalent coefficient: 1.25), and 1000 CX200 (equivalent coefficient: 0.625). Then, you can calculate the number of equivalent NEs in the IP domain as follows: Number of equivalent NEs in the IP domain = 5 x 10 + 200 x 1.25 + 1000 x 0.625 = 925





17-2

= Number of FTTx OLT equivalent NEs + Number of FTTx MDU equivalent NEs + Number of MSAN equivalent NEs + Number of DSLAM equivalent NEs + Number of equivalent NEs of other access equipment 

Number of FTTx OLT equivalent NEs = (Number of ONTs x Equivalent coefficient) + (Number of MDUs x Equivalent coefficient) + (Number of P2P ports x Equivalent coefficient)



Number of FTTx MDU equivalent NEs = (Number of ports of type_I x Equivalent coefficient) + ... + (Number of ports of type n x Equivalent coefficient)



Number of MSAN equivalent NEs = (Number of ports of type_I x Equivalent coefficient) + ... + (Number of ports of type n x Equivalent coefficient)



Number of DSLAM equivalent NEs = (Number of ports of type_I x Equivalent coefficient) + ... + (Number of ports of type_n x Equivalent coefficient)



Number of equivalent NEs of other access equipment = (Number of NEs of type_I x Equivalent coefficient) + ... + (Number of NEs of type_n x Equivalent coefficient)

The basic unit of an equivalent NE of the U2000 is OptiX Metro 1000.

The comparison coefficient of an equivalent NE of the U2000 to the equivalent NE in each domain is as follows: −

1 equivalent NE in the transport domain = 1 equivalent NE of the U2000

−

4 equivalent nodes in the IP domain = 1 equivalent NE of the U2000

−

3.3 equivalent nodes in the access domain = 1 equivalent NE of the U2000

The management scales of the U2000 are defined as follows: −

Small-scale network: less than 2,000 equivalent NEs of the U2000

−

Medium-scale network: less than 6,000 equivalent NEs of the U2000

−

Large-scale network: less than 15,000 equivalent NEs of the U2000

−

Extra-large-scale network: less than 20000 equivalent NEs of the U2000

Conversion between monitored instances to equivalent nodes: Monitored instances are converted into physical equivalent nodes as follows: 2 monitored instances = 1 equivalent NE of the U2000



Conversion between service resources to equivalent NEs. Service resource management needs to be converted into a certain number of equivalent nodes. The formulas for calculating the equivalent nodes are as follows: −

For 1-20,000 service resource licenses, Equivalent nodes of services = Total equivalent nodes x 20%

−

For 20,001-60,000 service resource licenses, Equivalent nodes of services = Total equivalent nodes x 25%

−

For 60,001-100,000 service resource licenses, Equivalent nodes of services = Total equivalent nodes x 30%

The management capability of the U2000 varies with hardware platforms, as shown in Table 17-1. Table 17-1 Management capabilities of the U2000 on different hardware platforms Server

A Abnormal Resource

When the NMS carries out the operation of device resource polling on the device management module or the module is refreshed manually, the physical resources of some devices, such as the card, sub-card and port, cannot be accessed because they have been deleted or have some faults. So, after the NMS carries out the operation of device resource polling on the device management module or the module is refreshed manually again, the result of polling the physical resources differ from the first time. The physical resources that cannot be polled in the second time are called the abnormal resource.

AIS insertion

If there are excessive errors in a channel, AIS can be inserted in this channel to indicate it is unavailable. For a line board, you can set whether to insert AIS when there are excessive errors in the B1, B2 and B3 bytes. For a tributary board at the E1 or T1 level, you can set whether to insert AIS when there are excessive errors in BIP-2. For a tributary board at the E3 level or higher, you can set whether to insert AIS when there are excessive errors in the B3 byte.

AIS

Alarm Indication Signal. A signal sent downstream in a digital network if an upstream failure has been detected and persists for a certain time.

Alarm correlation analysis

In the case alarm2 is raised within five seconds after alarm1 is raised, and alarm2 complies with the conditions defined in the alarm correlation analysis rule, you can either suppress the alarm2 or raise its severity level according to the behavior defined in the alarm correlation rule. Such a process is called alarm correlation analysis.

Alarm Level

Alarm level is to identify the severity of an alarm or event. It is divided up into four levels: critical, major, minor, warning alarm.

Alarm Status

Device reports the trap information to NMS. NMS displays the received information on the alarm start on the topological view. The alarm state contains four types: urgent alarm, important alarm, subordinate alarm and prompt alarm.

Alarm reversion

For the port that has already been configured but not actually loaded with services, this function can be used to avoid generating relevant alarm information, thus preventing alarm interference.

Alarm severity

According to ITU-T recommendations, the alarm is classified into four severities: Critical, Major, Minor, and Warning.

Path protection

The working principle of path protection: When the system works in path protection mode, the PDH path uses the dual-fed and signal selection mode. Through the tributary unit and cross-connect unit, the tributary signal is sent simultaneously to the east and west lines. Meanwhile, the cross-connect matrix sends the signal dually sent from the opposite end to the tributary board through the active and standby buses, and the hardware of the tributary board will selectively receive the signal from the two groups of buses automatically according to the AIS number of the lower order path.

View

Edits and displays the rule of the topology data or the filter conditions. It can be tailored according to the requirements Virtual fibre

A virtual fibre is created between SDH equipment that has WDM equipment in between. From SDH equipment perspective, creation of virtual fibres disassociates its fibre connection with WDM equipment and prevents impact on the auto fibre search function, ensuring independence of SDH trail management.From WDM equipment perspective, its service bearer layer is a virtual fibre instead of a true one after the virtual fibre is created. Deletion of the true fibre does not affect trail management.
