Abstract :
Survivable MPLS technologies are crucial in ensuring reliable communication services. The fast reroute (FRR) mechanism has been standardized to achieve fast local repair of label switched paths (LSPs). We present a hybrid survivability scheme for MPLS networks that combines the well-known p-cycle method with FRR technology. While with pure FRR backup paths are planned individually for each link, the hybrid scheme selects backup paths embedded within a set of p-cycles that may be selected by taking a holistic view of network performance. The hybrid FRR/p-cycle method is fully RFC 4090-compliant, yet allows network operators to leverage a large existing body of p-cycle design techniques.
