Title: Response to Updated draft Recommendation G.tpoam [Ref 043.02] Submission Date: 15th January 2011 From: IETF Liaison to ITU-T on MPLS stbryant@cisco.com To: tsbsg15@itu.int greg.jones@itu.int hiroshi.ota@itu.int iab@ietf.org CC: swallow@cisco.com loa@pi.nu paf@cisco.com stbryant@cisco.com adrian.farrel@huawei.com mpls@ietf.org yoichi.maeda@ttc.or.jp steve.trowbridge@alcatel-lucent.com ghani.abbas@ericsson.com hhelvoort@huawei.com malcolm.betts@zte.com.cn kam.lam@alcatel-lucent.com statements@ietf.org Response Contact: stbryant@cisco.com Technical Contact: stbryant@cisco.com Purpose: For Action Deadline: 15th March 2011 Thank you for your liaison statement "LS233 - Updated draft Recommendation G.tpoam [Ref 043.01]" The MPLS Working Group notes that this document contains text describing MPLS-TP OAM protocols not designed and standardized using the IETF Standards process. Specifically it uses material from draft-bhh-mpls-tp-oam-y1731-06. Please may we draw your attention to the status section of all Internet-Drafts which says: "Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress". Please also note that since the draft filename starts with the prefix string "draft-bhh" this clearly identifies it to the reader as a document expressing the personal technical views of the authors and hence hence as a document that that does not have any acknowledged level of IETF consensus. Since the text of draft Recommendation for G.tpoam is based on an MPLS-TP OAM protocol not designed within the IETF Standards Process this is a breach of the SG15 agreement with the IETF as published in "Report of the first meeting of Working Party 3/15 Transport network structures (2009-2012)" (Geneva, 1 – 12 December 2008) which can be found at http://www.itu.int/md/T09-SG15-R-0004/en. As a consequence the MPLS WG has not been asked to review this Draft Recommendation by the IETF management. When the ITU-T SG15 liaises a draft Recommendation written in accordance with the above agreement, IETF management will ask the MPLS WG to perform an in depth review. We look forward to receiving your next draft. Please confirm that the ITU-T intends to continue with the joint work on MPLS-TP and that the ITU-T will align this recommendation with the IETF MPLS-TP OAM design before advancing this document through the ITU-T publication process. You should also be aware of the IETF copyright rules. Please see http://trustee.ietf.org/license-info/archive/IETF- Trust-License-Policy-20091228.htm for further details. Since this draft Recommendation contains text in which the ITU-T SG15 has proposed making changes to IETF protocols without the approval of the IETF, the MPLS Working Group have referred this liaison to the IAB for their consideration. Please can we take this opportunity state that the IETF is committed to developing the MPLS-TP solution as described in the Joint Working Team Recommendations and meeting the jointly agreed MPLS-TP requirements documented in RFC5654.
