5650 Control Plane
Extending IP/MPLS Management with Integrated Control Plane Management and Visibility
A significant portion of service failures, provisioning problems and troubleshooting delays can be directly attributed to control plane
They make it difficult to provide more consistent service delivery quality. They impact the ability to offer stricter service level agreements (SLAs) that can differentiate service offerings. And they make it impossible to
Solving Control Plane Operational Issues with the 5650 CPAM
Service providers offering business critical services and delivery sensitive residential applications such as video can’t afford to let their customers down. Their reputation for consistent service delivery quality and adherence to SLAs is crucial. Since IP and MPLS provide the control plane technology that allows services to be rerouted around failures, leaving this critical technology unsupervised and manually operated can lead to unintended SLA violations. In addition, relying on scarce IP routing experts to provision and troubleshoot the MPLS infrastructure and services is not efficient for mainstream operations.
The 5650 CPAM delivers this functionality based on

But the advent of mission critical business services and service delivery sensitive subscriber services such as video — all riding over an IP/MPLS infrastructure — has changed service providers’ management needs. Simplifying service provisioning, reducing MTTR and assuring a high quality of service has become paramount.
The 5620 SAM allows operators to focus on managing services. It intelligently correlates corresponding network objects and the effect of their status on service delivery. This service management model provides

allows service providers to understand path changes through a comparison of historical and current paths.
By empowering network operators with simple visual tools that automatically track and correlate complex control plane topology, the 5650 CPAM decreases troubleshooting time and reliance on IP routing
experts to solve provisioning or customer reported problems. This comprehensive approach, although incremental in nature for AlcatelLucent 5620 SAM customers, represents a new foundation for managing IP/MPLS networks. It integrates element, network, and service and control plane management into a single IP/MPLS management solution [Figure 3].

Deployment in a Service Provider’s Network
Proactive Control Plane Surveillance
With proactive control plane surveillance, an alarm generated by the 5650 CPAM alerts operators that the routing plane is undergoing changes that exceed a configurable limit. Operators can navigate to a control plane topology map where all new or deleted IP routes are color coded to help them zero in on the routes affected by the routing updates [Figure 5].
The collected routing events can then be inspected for details about the changes that have occurred. In addition, operators can locate specific routes and LSPs that were affected by the changes and highlight the changes to discover whether the control plane behaved as expected.
The 5650 CPAM also enables specific source destination combinations to be actively monitored for routing changes using the MPLS tunnel and
IP route monitoring feature. Should changes be detected, the 5650 CPAM records the new route, which can later be highlighted and compared to the previous (historical) routes.
Control Plane Visualization, Validation and Diagnosis
In addition to this intuitive visual topology display, routing architects can trigger various queries that will compute
For troubleshooting MPLS protocols, the 5650 CPAM provides superimposed MPLS and IP protocol peering. This helps operators detect incomplete MPLS or IP peering that affect the MPLS protocol’s operation.
The 5650 CPAM also includes a powerful control plane configuration search engine that detects and highlights traffic engineering configurations that deviate from standard implementations (e.g. different traffic engineering parameters, incomplete peering, available bandwidth configuration, etc.)

The virtual private routed network (VPRN), virtual private line service (VPLS), virtual private wire service (VPWS) composite services, MPLS tunnels and LSPs provisioned (active and alternate paths) in the 5620 SAM can be highlighted over the 5650 CPAM control plane map. This feature allows operators to understand the path used to traverse the network, the number of hops along the path, whether the forward/return paths follow the same route and view all provisioned alternate paths for a given LSP [Figure 7].
Should the 5620 SAM SLA monitoring feature report service quality degradation, a network operator can extract the OAM trace results for the corresponding MPLS tunnel (path) from the 5620 SAM and verify if the path was recently changed. Any changes are graphically highlighted over the control plane topology map to provide a visual comparison between previous and current paths,
which might account for the sudden change in service quality.
While provisioning network infrastructure or services, network operators now have visualization and diagnostic tools at their fingertips that allow them to identify what is causing provisioning
