Abstract

A method and apparatus for analyzing a telecommunications network and providing data based on such analysis first retrieves topology data for the network. A maximum threshold of inter-node connections is specified and all routes under the threshold are identified. A cost is assigned to each individual link, and a total cost is determined for each route. The routes are then ranked according to their costs. Thereafter, a preferential route table is constructed for each node in the network which identifies every other node to which it is coupled. As a result, the resulting preferential route tables can be employed by dynamic restoration systems to dynamically build a restoral route following an outage in the network on a node-to-node basis.
