The detailed steps we've described for creating LSPs and tunnels are manual in nature. An NMS would substantially reduce the workload involved in creating these objects. We now describe a possible workflow for both cases:
At this point, all the necessary MIB tables are updated by NMS provisioning software. For the case of the tunnel, just the ingress node (Edge Router 1) MIB needs to be updated, with the remainder being signaled. For the LSP, if no signaling is used, then the NMS provisioning code must painstakingly update the MIBs of all the nodes in the path (Edge Router 1, Core Router 1, and Edge Router 2). Finally, the NMS should then report on the success or failure of the overall operation. Beyond this, the NMS should then start to manage the created connections as owned objectsobjects that it created. This differentiates between connections provisioned using the EMS (i.e., outside the NMS, using the CLI) rather than the NMS. |
