Protection Mechanisms for Label Distribution Protocol P2MP/MP2MP Label Switched Paths
Service providers continue to deploy real-time multicast applications using Multicast LDP (mLDP) across MPLS networks. There is a clear need to protect these real-time applications and to provide the shortest switching times in the event of failure. This document outlines the requirements, describes the protection mechanisms available, and where neccessary proposes extensions to facilitate mLDP P2MP and MP2MP LSP protection within an MPLS network.
