Abstract:
Techniques for computing a path for a local repair connection to be used to protect a connection traversing an original path from an ingress node to an egress node. The computed path originates at a node (start node) in the original path and terminates at another node (end node) in the original path that is downstream from the start node. A Constraint Shortest Path First (CSPF) algorithm may be used to compute the path. The computed path is such that it satisfies one or more constraints and does not traverse a path from a first node in the original path to a second node in the original path, wherein the first and second nodes are upstream from the start node in the original path and the second node is downstream from the first node in the original path. A local repair connection may then be signaled using the computed path.
