[mpls] Re: Working Group Last Call on draft-ietf-mpls-mna-hdr (2nd WG call)

Hi Tarek and WG,

I do not support the publication of this draft.
I agree with Jimmy there are serious concerns about ISD implementation and performance.
I believe ISD is not the right approach for MNA, we will not implement it.
I need a knob in existing MNA hdr to disable ISD and enable PSD.

Best,
Tianran

Hi Tarek,

Before the 1st WG LC, some implementation experience with the -04 version of this draft was presented on an interim meeting: https://datatracker.ietf.org/meeting/interim-2024-mpls-01/session/mpls. That implementation was from Academia.

As shown in the meeting materials, the implementors met some challenges with the encodings in -04 version, they asked some questions and also gave some proposals for possible optimization. As part of the WG LC, it would be important to check whether the issues raised at that time have be addressed by the latest version. It would be helpful if some feedback on the latest version can be provided by those implementors.

At IETF 120 I asked one question about the implementation report. Are we aware of any other implementation of this document, besides the implementation of the -04 version from Academia? This would be important to gauge the maturity of the document and the interest in implementing it.

Best regards,
Jie
