1 Overview

1.1 Equipment Introduction The OptiX PTN 3900 is new generation metropolitan optical transport platform, which is developed by Huawei for packet transport. As emerging data services are widely applied, operators require increasing bandwidth of the transport network and demand more flexibility of scheduling bandwidth. As a circuit-switching network, the traditional SDH-based multiservice transport network is inapplicable to the data services that feature burst and flexibility. In addition, the traditional connectionless IP network should not be used as a telecommunication carrier network because it cannot strictly ensure the quality and performance of important services. With the pseudo wire emulation edge-to-edge (PWE3) technology, the multi-protocol label switch (MPLS) technology, as well as ideal operation, administration and maintenance (OAM) and protection switching mechanism, the OptiX PTN 3900 is able to provide services of carrierclass quality in a packet transport network and SDH transport network.

1 Overview

1.2 Network Application The OptiX PTN 3900 is applied at the convergence layer and the backbone layer of a metropolitan transport network. The OptiX PTN 3900 is mainly used in the convergence layer and the backbone layer of a metropolitan transport network. It transports packet services in the network, and converges the services to an IP/MPLS backbone network. The OptiX PTN 3900 also supports the coarse wavelength division multiplexing (CWDM) networking and realizes the local wavelength grooming. In later versions, the OptiX PTN 3900 supports the SDH boards of the OptiX OSN 1500/2500/3500/7500 product series and supports the dense wavelength division multiplexing (DWDM) boards of the OptiX OSN 3800/6800 product series, to realize the networking with a WDM/SDH backbone network. This facilitates the smooth evolution of the metropolitan transport network from a time division multiplex (TDM) switching network to a packet switching network.

2 Functions and Features –

–

The control plane of the equipment supports the Ethernet loopback (ETH-LB) and Ethernet link trace (ETH-LT) operations. The equipment supports performance monitoring for the E-Line service. In compliance with ITU-T Y.1731, the equipment provides hardware support for the monitoring of packet loss ratio, packet delay, and packet delay variation.

At the link layer, the OptiX PTN 3900 supports the following OAM mechanisms. l

The equipment supports Ethernet OAM that is compliant with IEEE 802.3ah. Each Ethernet port supports link discovery, link state monitoring, remote fault indication, and remote loopback.

l

The equipment supports ATM OAM, including the fault management in the F4 OAM and F5 OAM.

2.8 NSF With the non-stop forwarding (NSF) function, data forwarding can be properly performed even when the control plane of the equipment is faulty (for example, the CPU is restarted). In this case, key services on the network are protected. The OptiX PTN 3900 supports the protocol level graceful restart (GR) technology (for example, the LDP GR). In the case of a fault, the neighbor nodes do not delete the route information. In this way, services are still forwarded and the network route oscillation is avoided. The OptiX PTN 3900 supports the NSF function in the following cases: l

The warm reset of the processing board and the XCS board.

l

The cold reset of the XCS board (the XCS board should be configured with 1+1 protection).

l

The reset of the SCA board (the SCA board should be configured with 1+1 protection).

2.9 Clock The OptiX PTN 3900 supports the physical layer clock synchronization mechanism, the external clock input/output, and the equipment internal clock. In addition, the OptiX PTN 3900 also supports the IEEE 1588 V2 clock synchronization

Physical Layer Clock Synchronization The clock system of the OptiX PTN 3900 supports extracting the clock information from the following transmission links: l

Extraction of clock signals from POS STM-1/STM-4 interfaces

l

Extraction of clock signals from channelized STM-1 interfaces

l

Extraction of clock signals from ATM STM-1 interfaces

l

Extraction of clock signals from synchronous Ethernet interfaces

l

Extraction of clock signals from E1 interfaces

The OptiX PTN 3900 supports input/output of two 75-ohm or two 120-ohm external clock sources, which are of 1+1 protection. 2-14


Issue 01 (2009-06-30)



The OptiX PTN 3900 supports three clock working modes, that is, the locked, hold-over, and free-run modes. The OptiX PTN 3900 also supports the processing and transfer of synchronization status messages (SSM). The synchronous Ethernet is a technology used to synchronize the clock at the Ethernet physical layer. Clock signals are extracted directly from the serial bit flow on the Ethernet link. These clock signals are then used for data transmission. In this way, the clock signals are transferred.

IEEE 1588 V2 IEEE 1588 V2 is a time synchronization protocol that provides the nanosecond accuracy to meet the requirements of 3G base stations. OptiX PTN 3900 supports the following features of IEEE 1588 V2: l

The equipment can use the IEEE 1588 V2 protocol to achieve the clock synchronization and time synchronization.

l

The equipment supports the boundary clock (BC) mode, ordinary clock (OC) mode, and transparent clock (TC)/(TC+OC) mode. The TC mode includes the end-to-end (E2E) TC mode and (P2P) TC mode.

l

The equipment supports the BMC algorithm to select clock source.

2.10 DCN Scheme The data communication network (DCN) is an integral part of network management, and is used to transmit the network management information. The OptiX PTN 3900 supports the inband DCN to ensure the intercommunication of network management information. The OptiX PTN 3900 adopts the inband DCN scheme. In this scheme, the setup of dedicated DCN channels is not required, and hence the network construction cost is greatly lowered. The OptiX PTN 3900 supports a maximum of 128 DCN channels. The OptiX PTN 3900 supports the inband DCN through the following interfaces. l
