Abstract:
A method for reconfiguring a telecommunications network comprising a plurality of reconfigurable cross-connect nodes interconnected by links when a failure event occurs is disclosed. The method comprises storing at each node a precomputed configuration table corresponding to each of a plurality of possible network topologies which can result from a plurality of possible failure events. After a specific failure event occurs, the network is flooded with messages so that each of the nodes is informed as to the specific existing topology of the network resulting from the specific failure event. The nodes are then reconfigurated in accordance with the precomputed configuration tables which correspond to the specific existing network topology.
