Claim One:
1. For use with a telecommunications network having nodes interconnected by edges, a method for restoring telecommunications traffic in the network following a disruption of traffic due to a circuit outage affecting traffic between nodes, comprising the steps of: (a) determining where within the network the outage occurred; (b) retrieving prestored circuit routing data from a central data base; (c) characterizing the telecommunications traffic disrupted by the outage as commodities for restoral; (d) developing a multicommodity model of the network based on the information obtained from steps (a) and (b); (e) establishing decision variables for determining actions potentially to be taken within the nodes; (f) applying a multicommodity algorithm to the model and to the decision variables to determine (i) reroutes available via spare and impacted edges and (ii) actions to be taken within the nodes for achieving said reroutes; (g) transmitting instructions for implementing the determined actions to all nodes affected by performance of step (f).
