Allocation of a Generic Associated Channel Type for ITU-T MPLS Transport Profile Operation, Maintenance, and Administration (MPLS-TP OAM)
Draft of message to be sent after approval:
From: The IESG <firstname.lastname@example.org> To: IETF-Announce <email@example.com> Cc: RFC Editor <firstname.lastname@example.org> Subject: Document Action: 'Allocation of a Generic Associated Channel Type for ITU-T MPLS Transport Profile Operation, Maintenance, and Administration (MPLS-TP OAM)' to Informational RFC (draft-betts-itu-oam-ach-code-point-04.txt) The IESG has approved the following document: - 'Allocation of a Generic Associated Channel Type for ITU-T MPLS Transport Profile Operation, Maintenance, and Administration (MPLS- TP OAM)' (draft-betts-itu-oam-ach-code-point-04.txt) as Informational RFC This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-betts-itu-oam-ach-code-point/
Technical Summary This document assigns a Generic Associated Channel (G-ACh) Type for carrying ITU-T MPLS Transport Profile Operations, Administration, and Management (MPLS-TP OAM) messages in the MPLS Generic Associated Channel. This document does not contain technical details of OAM for MPLS-TP networks. Those details are found in ITU-T determined Recommendation G.8113.1 that is a normative reference. Working Group Summary This document is an individual submission via AD sponsorship aiming to gain IETF consensus. It is not the product of a working group. IETF last call was notified to the MPLS and PWE3 working groups. This document does not make any comment on the judgement of the working groups in their technical decisions about which MPLS-TP OAM to standardise, but does observe that the MPLS WG selected a different OAM mechanism and that the IETF community considers the development of two sets of MPLS-TP OAM to be a bad idea. IETF last call saw an active debate, and the document has been updated to address the comments raised. Document Quality This document does not contain protocol details. Reports have been received suggesting implementation of G.8113.1 by four vendors with successful interoperability testing, and suggesting that more than 350,000 nodes have been deployed "that implement or will be upgraded to implement" the function described in G.8113.1. The publication of this document will be held in the normal way until the publication of the normative reference has been achieved. It is understood that this will require approval of G.8113.1 by the ITU-T. Personnel Huub van Helvoort (email@example.com) is the Document Shepherd.

RFC Editor Note Section1 para 2 s/Generic Associated Channel (G-ACh) Type/Generic Associated Channel (G-ACh) Type [RFC5586] --- Section 6.1 OLD [G.8113.1] ITU-T Recommendation ''Operations, Administration and Maintenance mechanism for MPLS-TP in Packet Transport Network (PTN)'' 10/12, http://www.itu.int/rec/T-REC-G.8113.1/en (Note to RFC editor: This link will become valid after G.8113.1 is approved) NEW [G.8113.1] ITU-T Recommendation ''Operations, Administration and Maintenance mechanism for MPLS-TP in Packet Transport Network (PTN)'' <date>, http://www.itu.int/rec/T-REC-G.8113.1/en [Notes to RFC editor: This link will become valid after G.8113.1 is approved. Please insert date of approval of G.8113.1.] END --- The RFC Editor should note that there is a normative reference to an unpublished ITU-T Recommendation, [G.8113.1]. The RFC Editor is requested to proceed as far as possible through the publication process for this RFC (including author review of the edited text) so that publication of the RFC can follow rapidly upon notification from the ITU-T should they decide to approve and publish their Reccomendation. Note that this will require coordination with the IANA as noted in the IANA Note below. --- IESG Note The IESG notes that the IETF has developed a set of OAM tools for MPLS-TP that have been published as Standards Track RFCs. A list of the relevant RFCs can be found in RFC xxxx. The approval of this document and the assignment of an ACh Type does not constitute endorsement by the IETF of the alternate MPLS-TP OAM documented in G.8113.1. The IESG recommends instead that the RFCs noted above should be implemented. [RFC Editor - please replace xxxx with the RFC number assigned to draft-ietf-mpls-tp-oam-analysis.] --- IANA Note IANA allocations should only be made against stable references. IANA is requested to make the allocation requested in this publication only once the ITU-T informs the IETF that G.8113.1 has passed all formal approvals and has been forwarded to their secretariat for final publication.
