This invention includes a path-based method and system that restore a distributed telecommunications network (90) from a failure condition (92). First, the method and system notify all the network nodes (22, 24, 26, 28) of the fault of a link (12). Next, an alternate route finding phase occurs for finding alternate paths (S-T1-T4-D) to reroute the disrupted traffic. For finding alternate paths (S-T1-T4-D), the alternate route finding phase includes sending messages (70, 100) throughout the distributed telecommunications network. Upon finding some alternate paths (S-T1-T4-D), the method and system send connect commands (100) to make the necessary cross connections in the distributed telecommunications network nodes (22, 24, 26, 28) that are on the alternate paths (S-T1-T4-D). Throughout the distributed network restoration process, the method and system synchronize (62) the distributed telecommunications network nodes to avoid possible race conditions among the nodes.
A method for restoring a distributed telecommunications network by re-routing traffic from one path to another when a link or a node in an original path fails, comprising the steps of:
A distributed telecommunications network having the ability to restore a distributed telecommunications network by rerouting traffic from one path to another when a link or a node in an original path fails, said distributed telecommunications network comprising:
