Technical Summary

   This document contains a number of updates to the Protection State
   Coordination (PSC) logic defined in RFC6378, "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 RFC6378.

    SG15 experts. There is a general agreement that these updates of
    RFC 6378 is necessary.

    The working group process were smooth, the document were reviewed 
    by he MPLS Review Team. There have been no controversies, but some
    constructive discussion on what should go in this document and what 
    belongs in draft-ietf-mpls-tp-psc-itu.
