GMPLS RSVP-TE Extensions for Ethernet
Operations, Administration, and Maintenance (OAM) Configuration
Abstract
The work related to GMPLS Ethernet Label Switching (GELS) extended
GMPLS RSVP-TE to support the establishment of Ethernet Label
Switching Paths (LSPs). IEEE Ethernet Connectivity Fault Management
(CFM) specifies an adjunct Operations, Administration, and
Maintenance (OAM) flow to check connectivity in Ethernet networks.
CFM can also be 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 the GMPLS RSVP-TE protocol to support the
setup of the associated Ethernet OAM entities of Ethernet LSPs and
defines the Ethernet technology-specific TLVs based on the GMPLS OAM
Configuration Framework. This document supports, but does not
modify, the IEEE and ITU-T OAM mechanisms.
