Re: [multipathtcp] Possible future items for mptcp WG

[Yoshifumi Nishida <[e-mail]>]

Hi Xavier,

Thanks. I think the timing you mentioned won't be a critical issue by
itself.
However, one question is how soon we can have concrete proposals to MPTCP
for 5G networks.
If there are already some solid features in 5G and we have explicit ideas
to update or extend MPTCP for them, I think there will be possibilities.
