An Overview of Operations, Administration, and Maintenance (OAM)
Data Plane Tools
draft-ietf-opsawg-oam-overview-10.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 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.
Status of this Memo
This Internet-Draft is submitted to IETF in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF), its areas, and its working groups. Note that
