draft-ietf-quic-multipath version

Which draft version does the multipath transmission protocol used in tquic?

@xuntyz It is based on the draft-ietf-quic-multipath-05 but doesn't fully adopt some of its complex designs. As you can see, later versions of the draft simplified some of these complex designs, making them more concise and elegant.

To ensure interoperability, you currently need to use tquic for both the client and the server.

Since the design of multipath may still change significantly, we will support the latest version of the draft at an appropriate time.

Hi, I came across this discussion while evaluating TQUIC for a probing tool I’m building. I noticed that the multipath implementation is based on draft-ietf-quic-multipath-05.

Since this discussion, the QUIC multipath draft has evolved quite a bit - for instance, draft-ietf-quic-multipath-09 introduced initial_max_path_id to negotiate multipath capability, and the latest version (-17) includes further updates and simplifications.

Are there any plans to update TQUIC’s implementation to follow a more recent draft version, or to track the current spec as it stabilises? It would be useful to know for interoperability and testing purposes.
