                      GMPLS RSVP-TE Extensions for
    Operations, Administration, and Maintenance (OAM) Configuration

Abstract

   Operations, Administration, and Maintenance (OAM) is an integral part
   of transport connections; hence, it is required that OAM functions be
   activated/deactivated in sync with connection commissioning/
   decommissioning, in order to avoid spurious alarms and ensure
   consistent operation.  In certain technologies, OAM entities are
   inherently established once the connection is set up, while other
   technologies require extra configuration to establish and configure
   OAM entities.  This document specifies extensions to Resource
   Reservation Protocol - Traffic Engineering (RSVP-TE) to support the
   establishment and configuration of OAM entities along with Label
   Switched Path signaling.
