This document describes requirements and solutions for MPLS-TP Shared ring protection (MSRP) in ring topology for point to point (P2P) services. The mechanisms of MSRP are illustrated and analyzed how to satisfy the MPLS-TP requirements in RFC5654 for optimized ring protection. MSRP could support wrapping and steering protection mechanisms for P2P services, which provide a simple and reliable protection switching. The survivability of the network could be improved and the operation and maintain could be more easy. Ring protection solution for p2mp services will be documented in another draft latterly.
