Hi Tarek et al,

I believe ultimately our goal is to have a single unified solution, but that doesn't mean the whole solution must be covered in a single document. We just need to ensure all the pieces can fit together as an integral part of the unified solution. For MNA, I think in-stack and post-stack mechanisms are quite different by nature and need to take care of different set of issues. Meanwhile, they are also relatively independent and have different maturity levels.  Therefore, they could be addressed and evolve separately. On top of these, when every piece is ready, we can have a document to glue them together to form a unified solution.

Thanks,
Haoyu

Subject: [mpls] Poll on way forward for MNA solution

Dear MPLS WG and MPLS Open DT,

Over the past months, the MPLS Open DT has reviewed several proposals for the packet encodings for the MNA solution.
A compilation of the multiple solutions brought forward is present at https://trac.ietf.org/trac/mpls/wiki/MNADocumnets<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftrac.ietf.org%2Ftrac%2Fmpls%2Fwiki%2FMNADocumnets&data=05%7C01%7Chaoyu.song%40futurewei.com%7C22615ce388fe46023d2208da9038ad51%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C1%7C637980870361732629%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000%7C%7C%7C&sdata=Z%2BYkwwsOlGGPGe6fFvbJ1In6%2Bg4TdjzMJ803f1LX7%2Bo%3D&reserved=0>.

We believe that currently there are two alternative ways to progress the MNA solution.
One of them requires a single unified solution, and the other allows for individual solutions to progress independently.
We expect any unified solution to document the pieces from the presented solutions that are discussed and agreed upon in the weekly MPLS Open DT meeting.
The co-chairs for the working groups hosting the Open MPLS DT are polling the WG on their preference to move forward.
Please respond with either:
    A) "I support the MPLS Open DT bringing forward a single unified solution"
    OR
    B) "I support progressing the individual solution(s) independently"

We will allow this poll to run for two weeks (ending on Sept 19th).

Regards,
Tarek (for the MPLS Open DT co-chairs)
