Abstract:
1. A method for dynamic protection of virtual links for paths of an optical network in communication with an IP network, the method comprising: establishing two or more Generalized MultiProtocol Label Switching (MPLS) paths within the optical network; grouping two or more of said GMPLS paths in a dynamic bundle, the grouping selected at a GMPLS control plane; and performing an end-to-end recovery on one of said GMPLS paths from its source node to its destination node; wherein said bundle of paths are recognized as a single routing adjacency in the IP network such that as long as one or more paths within the bundle is operating the routing adjacency in the IP network is not affected by changes within said bundle and protection decisions are made without the GMPLS control plane.
