Dear all,

Following the different feedbacks on this draft, we have proposed an updated version on the "Transport parameters for 0-RTT connections".
https://datatracker.ietf.org/doc/draft-kuhn-quic-0rtt-bdp/

The draft proposes a solution where path characteristics are shared between the peers to improve the ingress traffic for 0-RTT connections.

The difference with version 01 are mainly based on the received feedback.
In short, we now a BDP_metadata structure so that various path parameters can be exposed to the client (MTU, RTT, bandwidth, loss-rate).
We have also added a section to discuss what happens when BDP is used incorrectly.

Let us know if we have any views or interest in this proposal.

Cheers,

Nico for the authors
