Updates to MPLS Transport Profile Linear Protection
This document contains a number of updates to the Protection State Coordination (PSC) logic defined in RFC 6378, "MPLS Transport Profile (MPLS-TP) Linear Protection". These updates provide some rules and recommendations around the use of TLVs in PSC, address some issues raised in an ITU-T liaison statement, and clarify PSC's behavior in a case not well explained in RFC 6378.
