                              An Overview of
          Operations, Administration, and Maintenance (OAM) Tools
                   draft-ietf-opsawg-oam-overview-16.txt

Abstract

   Operations, Administration, and Maintenance (OAM) is a general term
   that refers to a toolset for fault detection and isolation, and for
   performance measurement. Over the years various OAM tools have been
   defined for various layers in the protocol stack.

   This document summarizes some of the OAM tools defined in the IETF in
   the context of IP unicast, MPLS, MPLS Transport Profile (MPLS-TP),
   pseudowires, and TRILL. This document focuses on tools for detecting
   and isolating failures in networks and for performance monitoring.
   Control and management aspects of OAM are outside the scope of this
   document. Network repair functions such as Fast Reroute (FRR) and
   protection switching, which are often triggered by OAM protocols, are
   also out of the scope of this document.

   The target audience of this document includes network equipment
   vendors, network operators and standards development organizations,
   and can be used as an index to some of the main OAM tools defined in
   the IETF. This document provides a brief description of each of the
   OAM tools in the IETF. At the end of the document a list of the OAM
   toolsets and a list of the OAM functions are presented as a summary.
