Using a Generic Associated Channel Label as a Virtual Circuit Connectivity Verification Channel Indicator
RFC 7708, “Using a Generic Associated Channel Label as a Virtual Circuit Connectivity Verification Channel Indicator”, is a Proposed Standard document published in November 2015 by T. Nadeau, L. Martini, S. Bryant. The canonical text is published by the RFC Editor.
Abstract
The Virtual Circuit Connectivity Verification (VCCV) protocol specified in RFC 5085 provides a control channel (CC) that is associated with a pseudowire (PW). This document specifies an additional VCCV control channel type to be used with pseudowires that do not use the PW Control Word and that are carried over an MPLS network. This new VCCV CC type uses the Generic Associated Channel Label defined in RFC 5586 to distinguish VCCV packets from packets carrying user data. This new VCCV CC type introduces compatibility with the method of MPLS Label Switched Path Operations, Administration, and Maintenance (OAM) identification, particularly in MPLS Transport Profile (MPLS-TP) networks (RFC 5921).
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
