     Network Management Framework for MPLS-based Transport Networks

Abstract

   This document provides the network management framework for the
   Transport Profile for Multi-Protocol Label Switching (MPLS-TP).

   This framework relies on the management terminology from the ITU-T to
   describe the management architecture that could be used for an MPLS-
   TP management network.

   The management of the MPLS-TP network could be based on multi-tiered
   distributed management systems.  This document provides a description
   of the network and element management architectures that could be
   applied and also describes heuristics associated with fault,
   configuration, and performance aspects of the management system.

   This document is a product of a joint Internet Engineering Task Force
   (IETF) / International Telecommunication Union Telecommunication
   Standardization Sector (ITU-T) effort to include an MPLS Transport
   Profile within the IETF MPLS and PWE3 architectures to support the
   capabilities and functionalities of a packet transport network.
