Hi Adrian, Thanks for working on the liaison response. The updated text look good to me. Best regards, Jie From: mpls [mailto:mpls-bounces@ietf.org] On Behalf Of Adrian Farrel Sent: Monday, March 11, 2024 12:59 AM To: 'Alexander Vainshtein' <Alexander.Vainshtein@rbbn.com>; 'BRUNGARD, DEBORAH A' <db3546@att.com> Cc: mpls-ads@ietf.org; 'mpls' <mpls@ietf.org> Subject: Re: [mpls] For Review: Proposed Liaison Response to SG11 Hi Sasha, Thank you for your consideration. I share some of your experiences with T-MPLS and am consequently also concerned that any protocol work should be carried out in the IETF. But I am not sure that one SDO should tell another SDO that publication of their requirements document is unjustified. To some extent, I read Q.3962 as indicating the deployment model that some operators want to follow, and you can’t argue with that. If the requirements can be met with existing tools, then I am sure that an “applicability statement” could be written in the IETF, and I am sure that the WG would be happy to help review the work. Obviously, no one should be under the illusion that they can commission a draft and have it written for them :-) If it turns out that the requirements cannot be met with existing tools, and that protocol extensions are needed, then (of course) the IETF is the place to do that, and the WG would clearly want to review the proposals before taking them through the usual IETF process. So perhaps we can strengthen this with… OLD Our current understanding of your requirements suggests that all or most of your requirements can be addressed using existing IP/MPLS OAM tools. NEW Our current understanding of your requirements suggests that all or most of your requirements can be addressed using existing IP/MPLS OAM tools, and that no further protocol work is necessary. END We also have s/lacunae/gaps/ from Loa. Further, if we *really* want to make the point clear we should change… OLD Obviously, should any gaps be discovered during this process, the working group would also be pleased to engage in additional protocol work to resolve any issues. NEW Obviously, should any gaps be discovered during this process, the working group would also be pleased to engage in additional protocol work to resolve any issues using the procedures described in RFC 4775 and RFC 4929.

Specifically, something like (proposed added text is highlighted): “Our current understanding of your requirements suggests that all or most of your requirements can be addressed using existing IP/MPLS OAM tools, so that it is not clear to the WG whether publication of Q.3962 in its present form is justified”. IMHO and FWIW this sits well with the proposal to “all experts to bring these requirements to the IETF's MPLS working group with a view to working collaboratively on an Informational RFC that describes how to deliver the function you want to see”, My 2c, Sasha From: mpls <mpls-bounces@ietf.org<mailto:mpls-bounces@ietf.org>> On Behalf Of BRUNGARD, DEBORAH A Sent: Friday, March 8, 2024 6:10 PM To: adrian@olddog.co.uk<mailto:adrian@olddog.co.uk>; 'mpls' <mpls@ietf.org<mailto:mpls@ietf.org>> Cc: mpls-ads@ietf.org<mailto:mpls-ads@ietf.org> Subject: [EXTERNAL] Re: [mpls] For Review: Proposed Liaison Response to SG11 +1 +1 on “soon” – SG11 will meet early May with contributions due Ap 18 – so hopefully with early receipt of this liaison, will help contributors on progressing their on-going work items.
