  An Overview of the Operations, Administration, and Maintenance (OAM)
               Toolset for MPLS-Based Transport Networks

Abstract

   This document provides an overview of the Operations, Administration,
   and Maintenance (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)
   that 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 the MPLS Transport Profile
   (MPLS-TP) OAM requirements and functions and the generic mechanisms
   created in the MPLS data plane that allow the OAM packets to 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 documents), which are referenced by
   this document.
