   Network Management Requirements for MPLS-based Transport Networks

Abstract

   This document specifies the requirements for the management of
   equipment used in networks supporting an MPLS Transport Profile
   (MPLS-TP).  The requirements are defined for specification of
   network management aspects of protocol mechanisms and procedures
   that constitute the building blocks out of which the MPLS
   Transport Profile is constructed.  That is, these requirements
   indicate what management capabilities need to be available in
   MPLS for use in managing the MPLS-TP.  This document is intended
   to identify essential network management capabilities, not to
   specify what functions any particular MPLS implementation
   supports.
