Liaisons referred by this one LS on need for Multi-Path QUIC for ATSSS
Body
Thank you for your input to our specifications.

Multipath capabilities for QUIC are currently under active discussion in the
IETF's QUIC WG. Several individual proposals have been made, but the group is
also considering whether the already-specified connection migration capabilities
are sufficient to cover the majority of use cases.

We encourage 3GPP to contribute their requirements for QUIC multipath capabilities
in an Internet-Draft, especially if the already-specified connection migration
capabilities are deemed insufficient. 3GPP's active involvement in any multipath
QUIC standardization would be the best way to remain informed of the progress of
any such work in the IETF.

Kind regards,
Mark Nottingham, Lucas Pardue and Lars Eggert, QUIC Working Group chairs
