ABSTRACT:
Techniques for configuring a local repair connection for a protected connection including determining a path for the local repair connection. The path traversed by a local repair connection starts at a node in the path associated with the protected connection and ends at a merge point node in the path associated with the protected connection that is downstream from the start node. In one embodiment, the merge point node may even be more than two hops downstream from the start node in the path associated with the protected connection. The local repair path may include zero or more nodes that are not included in the path associated with the protected connection. Techniques are also described for optimizing the path associated with a local repair connection.
