From: The IESG <firstname.lastname@example.org> To: IETF-Announce <email@example.com> Cc: RFC Editor <firstname.lastname@example.org>, pwe3 mailing list <email@example.com>, pwe3 chair <firstname.lastname@example.org> Subject: Protocol Action: 'VCCV MPLS-TP Connectivity Verification (CV) Capability Advertisement' to Proposed Standard (draft-ietf-pwe3-mpls-tp-cv-adv-06.txt) The IESG has approved the following document: - 'VCCV MPLS-TP Connectivity Verification (CV) Capability Advertisement' (draft-ietf-pwe3-mpls-tp-cv-adv-06.txt) as Proposed Standard This document is the product of the Pseudowire Emulation Edge to Edge Working Group. The IESG contact persons are Stewart Bryant and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-pwe3-mpls-tp-cv-adv/
Technical Summary This document specifies how signaling and selection processes for Pseudowire (PW) Virtual Circuit Connectivity Verification (VCCV) are modified to ensure backward compatibility and allow use of proactive Connectivity Verification (CV), Continuity Check (CC), and Remote Defect Indication (RDI) over MPLS Transport Profile (MPLS-TP) PWs. This document introduces four new CV types and, to accommodate them, a new VCCV Extended CV parameter for PW Interface Parameters Sub-TLV is defined. Working Group Summary This was a straightforward document as far as the WG was concern. The majority of discussion of the draft occurred while it was an individual draft, when it went though several round of comments and revisions before being adopted as a WG draft. Document Quality There are no known implementations of the draft at this time. At least one vendor has it under consideration for implementation. Personnel Andy Malis is the Document Shepherd.
