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.
