Hello Lars and others

How about the following addition below? I know it leaves widely open what kind of experimentations would be helpful. I

Bets regards
Hannu

-------

Thank you for the update on your architectural design and your intended standardization timeline.

Multipath support for QUIC remains under active discussion in the IETF QUIC working group. While multiple design proposals for such an extension have been proposed, it remains uncertain for the time being if the WG will come to consensus on adopting a work item on multipath QUIC, and if so, which individual proposal it would be based on and whether or not it would satisfy your architectural design. To help with the selection process we are calling for experimentation results to better understand the design scape options. We unfortunately also cannot predict whether the WG discussion will have sufficiently progressed by March 2021 for such a consensus to emerge.

could you make a text suggestion? It's not fully clear to me what you think we should say.

I'm not Hannu, so Hannu should answer this, but if you do end up with text about experimentation in the proposed liaison back, you might point out that the QUIC working group would appreciate hearing results of experimentation from people who participate in 3GPP.

We often remind other SDOs that the best way to work IETF is to participate in IETF working groups (and that's exactly what https://datatracker.ietf.org/doc/rfc3113/?include_text=1 says explicitly to 3GPP), but saying "and please tell us your experimental results" is different enough from other ways that other SDOs have worked with the IETF, that it might be worth saying explicitly.

Do The Right Thing, of course.

Best,

Spencer

Thanks,
Lars
