      An Overview of Operations, Administration, and Maintenance (OAM)

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 data plane OAM tools defined in
   the IETF in the context of IP unicast, MPLS, pseudowires, MPLS for
   the transport profile (MPLS-TP), and TRILL.

   The target audience of this document includes network equipment
   vendors, network operators and standard development organizations,
   and can be used as an index to some of the main data plane OAM tools
   defined in the IETF.
