ABSTRACT:
A method and apparatus for analyzing a telecommunications network and providing data based on such analysis first receives physical topology data for the network based on nodes and their connections in the network. Thereafter, the method and apparatus identify several inter-node configurations in the network. Preferably, the method and apparatus identify six inter-node configurations: stranded network non-rings, non-ring network spurs, stranded network rings, spur nodes with path diversity, network segments with pass-through nodes, and network segments without pass-through nodes. From these six identified inter-node configurations, the method and apparatus identify failure spans or maximum lengths in a network that can be singularly restored. As a result, the six identified inter-node configurations or failure spans can be employed to reduce the processing time required under network restoration systems, and thus can be used to minimize the time required to isolate a failure and generate a restoral route in the network.
