Abstract:
1. A method of facilitating creation of a local repair connection for a first connection, the first connection traversing an original path comprising a plurality of nodes, the method comprising: determining a first local repair path from a point of local repair (PLR) node to a merge point (MP) node, wherein the PLR node and the MP node are in the original path and the MP node is downstream from the PLR node in the original path; determining that the first local repair path comprises a first node that is also in the original path, where the first node is downstream from the PLR node in the first local repair path and is upstream from the MP node in the first local repair path, and wherein the first node is downstream from the PLR node in the original path; determining a second local repair path starting at the PLR node of the first local repair path and ending at the first node; and establishing a local repair connection using the second local repair path instead of the first local repair path.
