Summary

Recommendation ITU-T G.8133 provides architecture and mechanisms for pseudowire (PW) dual-homing protection in multi-protocol label switching transport profile (MPLS-TP) networks. It also describes the dual-homing coordination (DHC) protocol described in [IETF RFC 8184] and [IETF RFC 8185].

The mechanisms defined herein protect point-to-point MPLS-TP PWs against failures within or at the edges of the MPLS-TP network.
