   An Overview of the OAM Tool Set for  MPLS based Transport Networks
                 draft-ietf-mpls-tp-oam-analysis-08.txt

Abstract

   This document provides an overview of the OAM toolset for MPLS based
   Transport Networks.  The toolset consists of a comprehensive set of
   fault management and performance monitoring capabilities (operating
   in the data-plane) which are appropriate for transport networks as
   required in RFC 5860 and support the network and services at
   different nested levels.  This overview includes a brief recap of
   MPLS-TP OAM requirements and functions, and of generic mechanisms
   created in the MPLS data plane to allow the OAM packets run in-band
   and share their fate with data packets.  The protocol definitions for
   each of the MPLS-TP OAM tools are defined in separate documents (RFCs
   or Working Group drafts) which are referenced by this document.
