         Integrated Operation, Administration, and Maintenance
                   draft-mmm-rtgwg-integrated-oam-00

Abstract

   This document describes the Integrated Operation, Administration, and
   Maintenance (IntOAM) protocol.  IntOAM is based on the lightweight
   capabilities of Bidirectional Forwarding Detection defined in RFC
   5880 Bidirectional Forwarding Detection, and the RFC 6374 Packet Loss
   and Delay Measurement for MPLS Networks to measure performance
   metrics like packet loss and packet delay.  Also, a method to perform
   lightweight on-demand authentication is defined in this
   specification.

1.  Introduction

   [RFC5880] has provided the base specification of Bidirectional
   Forwarding Detection (BFD) as the light-weight mechanism to monitor a
   path continuity between two systems and detect a failure in the data-
   plane.  Since its introduction, BFD has been broadly deployed.  There
