An Overview of the OAM Tool Set for MPLS based Transport Networks
draft-ietf-mpls-tp-oam-analysis-08.txt
Abstract
This document provides an overview of the 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) which 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
MPLS-TP OAM requirements and functions, and of generic mechanisms
created in the MPLS data plane to allow the OAM packets 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 drafts) which are referenced by this document.
Status of this Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
