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.
