Title: Response to Updated draft Recommendation G.8121 [Ref 042.03] Submission Date: 10th February 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 updated liaison statement "LS232 - Updated draft Recommendation G.8121 [Ref 042.01]" attaching WD19r2. Please may I refer you to our earlier response of 15th January 2011 entitled "Response to Updated draft Recommendation G.8121 [Ref 042.02]" Additionally, since the text of draft Recommendation for G.8121 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 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.
