ABSTRACT:
A distributed method and system for excluding segments from use in bypassing a failed component. Prior to failure of a segment, the restoration system at a central location identifies each path in the communications network. A path is a unique sequence of installations that a segment traverses. The restoration system then creates a mapping of the ports of the restoration nodes to the paths of the segments connected to each port. The restoration system then identifies for each path the set of paths that are interdependent. A pair of paths are interdependent when both paths traverse a common pair of installations. The restoration system then downloads to each restoration node the mappings for its ports along with an indication of the paths that are interdependent with the path of each segment connected to the restoration node. Following failure of a segment, the restoration node that detects the failure uses the downloaded mapping to identify the failed path and notifies the other restoration nodes of the failed path. The restoration system at each restoration node then excludes each segment that has a path that is interdependent with the failed path when implementing a restoral route.
