            MPLS-TP Identifiers Following ITU-T Conventions
                draft-ietf-mpls-tp-itu-t-identifiers-02

Abstract

   This document specifies an extension to the identifiers to be used in
   the Transport Profile of Multiprotocol Label Switching (MPLS-TP).
   Identifiers that follow IP/MPLS conventions have already been
   defined.  This memo augments that set of identifiers for MPLS-TP
   management and OAM functions to include identifier information in a
   format typically used by the ITU-T.

Internet-Draft              MPLS-TP ITU-T IDs               October 2011

1.  Introduction

   This document augments the initial set of identifiers to be used in
   the Transport Profile of Multiprotocol Label Switching (MPLS-TP)
   specified in RFC 6370 [RFC6370].

   RFC 6370 [RFC6370] defines a set of MPLS-TP transport and management
   entity identifiers to support bidirectional (co-routed and
   associated) point-to-point MPLS-TP LSPs, including PWs and Sections
   which follow the IP/MPLS conventions.

   This document specifies an alternative way to uniquely identify an
   operator/service provider based on ITU-T conventions and specifies
   how this operator/service provider identifier can be used to make the
   existing set of MPLS-TP transport and management entity identifiers,
   defined by RFC 6370 [RFC6370], globally unique.

   This document solely defines those identifiers.  Their use and
   possible protocols extensions to carry them is out of scope in this
   document.

   In this document, we follow the notational convention laid out in RFC
