GMPLS RSVP-TE Extensions for Ethernet OAM Configuration
draft-ietf-ccamp-rsvp-te-eth-oam-ext-09
Abstract
The GMPLS controlled Ethernet Label Switching (GELS) work extended
GMPLS RSVP-TE to support the establishment of Ethernet LSPs. IEEE
Ethernet Connectivity Fault Management (CFM) specifies an adjunct OAM
flow to check connectivity in Ethernet networks. CFM can be also
used with Ethernet LSPs for fault detection and triggering recovery
mechanisms. The ITU-T Y.1731 specification builds on CFM and
specifies additional OAM mechanisms, including Performance
Monitoring, for Ethernet networks. This document specifies
extensions of GMPLS RSVP-TE to support the setup of the associated
Ethernet OAM entities of Ethernet LSPs, and defines the Ethernet
technology specific TLV based on [OAM-CONF-FWK].
