Hello,

Thank you for working on the slides and sharing them beforehand. They gave
mea  good understanding on what the requirements from ATSSS would be.

I have one question: Regarding feature breakdown in pp. 7-8, would it be
the case that the server address can be stable throughout the lifetime of a
QUIC connection for all the bullet points? Or would it be the case that the
server has to migrate to a different address mid-connection?

What I am wondering is if path validation scheme that we have in QUICv1
would be sufficient for supporting ATSSS, or if simultaneous migration
would be required.

I think that having that point clarified (possibly during the presentation)
would help us better understand the amount of work we need to devote if we
decide to design features necessary for ATSSS.

Thank you in advance.
