Re: Draft response to Liaison Statement, "LS on ATSSS Phase 2 Requirements to IETF QUIC Working Group"

[Magnus Westerlund <[e-mail]>]

Hi Lars,

So I think your comment about discussion of abandoning Multi-path may have come
as a surprise to some people. Where has that discussion occurred? 

It wasn't on this mailing list what I can find. It doesn't like like an
exstensive discussion on the QUICDEV slack either, I did find 10 messages in
total. And that is not official WG resource either. I did find one github issue
that have some discussion. But larger issues like this really should be brought
to the WG mailing list. 

So I think before you do send a LS reply lets conclude on the now started
discussion here on the mailing list. 

Cheers

Magnus Westerlund
