                              An Overview of
        Operations, Administration, and Maintenance (OAM) Mechanisms
                   draft-ietf-opsawg-oam-overview-08.txt

Abstract

   Operations, Administration, and Maintenance (OAM) is a general term
   that refers to a toolset that can be used for fault detection and
   isolation, and for performance measurement. OAM mechanisms have been
   defined for various layers in the protocol stack, and are used with a
   variety of protocols.

   This document presents an overview of the OAM mechanisms that have
   been defined and are currently being defined by the IETF.
