Backhaul Network Model
Logical backhaul network elements Nodes: Source or destination of backhaul traffic Segments: Logical connections between nodes
Network topology Source and destination nodes
Backhaul Nodes
Source or destination of backhaul traffic A node can be a source of traffic towards another node or a destination of traffic from other nodes A node may generate TDM as well as Ethernet traffic Traffic statistics and data may be generated using Monte Carlo simulations in Atoll radio access technology modules
A radio site can house one or more logical backhaul node Example: Co-located base stations of different radio access technologies
Backhaul Segments
Logical connections between source and destination nodes Outline the backhaul network hierarchy (topology) by defining interlinked source and destination nodes May carry TDM and Ethernet (circuit and packet) traffic with support for IP overbooking
Segment-to-link mapping A segment may be relayed on one link or on several links (e.g., two parallel leased lines) A link may relay more than one segment (e.g., two segments carrying traffic from different access technologies using the same link)
Segment bandwidth Data transfer bandwidth between nodes depends on the underlying link(s)
Backhaul Traffic Routing
Calculation of optimum traffic routes between two selected nodes
Calculation based on Line-of-sight clearance Bandwidths of existing routes (segments)
Traffic routing analysis Detailed routing results with dynamic evaluation on the map Possibility for the user to choose the ideal route
Backhaul Subnetwork Building
Calculation of the optimum traffic routes from multiple source nodes to a destination node
Calculation based on Distance between source and destination nodes Line-of-sight clearance between nodes Number of hops between source and destination nodes Existing routes, segments, and links
Backhaul Capacity Planning
Analysis of current backhaul network capacity Identifying bottlenecks within an entire network, in a subnetwork, along a selected route
Backhaul network dimensioning Capacity analysis with under different traffic forecasts
Calculations based on All elements of the tree under a destination node Traffic demands of each node Traffic aggregation at subsequent nodes Traffic scaling (forecast) IP overbooking
Backhaul Capacity Analysis
Analysis of capacity and compatibility between segments and links Means to assess consistency between logical and physical backhaul network elements Identifies segments/links that require upgrades
Analysis of complex backhaul scenarios A segment relayed over more than one link More than one segments relayed over a single link
Backhaul Breakdown Analysis
Analysis of backhaul network behaviour under breakdowns Radio equipment breakdown simulation Link failure simulation
Analysis enables you to design a robust network by Anticipating unforeseen events and assessing possible intermediate solutions Evaluating the consequences of the breakdown of one network element on another Analysing possible alternate traffic routes for maintaining quality of service
