Re: [mpls] For Review: Proposed Liaison Response to SG11

[Alexander Vainshtein <[e-mail]>]

Adrian, Deborah and all,
I may be somewhat biased about this issue based on experience with MPLS-TP, but maybe a slightly stronger language could be used in our response?


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

+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.

Hi WG, You may have seen some back and forth on the list with respect to a liaison statement sent "For Information" to the OPSAWG by ITU-T Study Group 11. Watching the mailing list, your chairs thought it would be a good idea to send a response


Hi WG,



You may have seen some back and forth on the list with respect to a liaison

statement sent "For Information" to the OPSAWG by ITU-T Study Group 11.



Watching the mailing list, your chairs thought it would be a good idea to

send a response even though one is not requested or required, and even

though we were not the original recipients of the incoming liaison.



Our draft is below. We would welcome any thoughts or edits.



The intention is to send this "soon" so it would help if you could respond

in a timely way.



Thanks,

Adrian for the MPLS Chairs

Body:



Thank you for your Liaison Statement - LS on the consent of draft

Recommendation ITU-T Q.3962 (ex. Q.joint_tr) "Requirements and Reference

Model for optimized traceroute of joint Internet Protocol/Multi-Protocol

Label Switching" dated 2023-10-24. This has been passed on to the MPLS

working group for consideration.



The MPLS working group would like to thank you for sharing your requirements

as expressed in Q.3962.



Our current understanding of your requirements suggests that all or most of

your requirements can be addressed using existing IP/MPLS OAM tools.



We would welcome 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. Obviously,

should any lacunae be discovered during this process, the working group

would also be pleased to engage in additional protocol work to resolve any

issues.



Kind regards,

Adrian Farrel MPLS Working Group Co-Chair

On behalf of the MPLS Working Group and Co-Chairs
