Summary

Recommendation ITU-T G.8132/Y.1383 provides architecture and mechanisms for shared ring protection for multi-protocol label switching-transport profile (MPLS-TP) networks. It describes the MPLS-TP shared ring protection (MSRP) mechanisms and the ring protection switch (RPS) protocol.

The mechanisms defined herein protect point-to-point MPLS-TP label switched paths (LSPs) against failures at the MPLS-TP section layer.
