Would it be practical to lift the 32-bit constraint on the CID sequence number? Even if it probably is enough for most use cases I find it unfortunate to introduce a new constraint here because if affects design decisions elsewhere in stack. For example, it could be required that a key is updated at least once in every 2^31 sequence numbers, or the IV could be hashed and use a sufficiently frequent key update.

Please check this link: https://tools.ietf.org/html/draft-liu-multipath-quic-01 Regarding the questions in the mailing list for the previous version: 1. We have fixed the IANA registry problem in the new version. Thanks Lucas for pointing out this problem. 2. We currently use Github for editing, and we prefer discussions on the mailing list, so we removed the Github link in this draft. This version merges our draft and Christian’s draft, and here are some of the key features: * Re-use as much as possible mechanisms of QUIC-v1, which has supported connection migration and path validation. * To avoid the risk of packets being dropped by middleboxes (which may only support QUIC-v1), use the same packet header formats as QUIC V1. * Endpoints need a Path Identifier for each different path which is used to track states of packets. As we want to keep the packet header formats unchanged [QUIC-TRANSPORT], Connection IDs (and the sequence number of Connection IDs) would be a good choice of Path Identifier. * For the convenience of packet loss detection and recovery, endpoints use a different packet number space for each Path Identifier. * Congestion Control, RTT measurements and PMTU discovery should be per-path (following [QUIC-TRANSPORT]) Thanks Jana and Kazuho for reviewing the proposal. We would like to know how people think about the draft, and all feedbacks and suggestions are welcome!

Name: draft-liu-multipath-quic Revision: 01 Title: Multipath Extension for QUIC Document date: 2020-12-14 Group: Individual Submission Pages: 18 URL: https://www.ietf.org/archive/id/draft-liu-multipath-quic-01.txt Status: https://datatracker.ietf.org/doc/draft-liu-multipath-quic/ Htmlized: https://datatracker.ietf.org/doc/html/draft-liu-multipath-quic Htmlized: https://tools.ietf.org/html/draft-liu-multipath-quic-01 Diff: https://www.ietf.org/rfcdiff?url2=draft-liu-multipath-quic-01 Abstract: This document specifies multipath extension for the QUIC protocol to enable the simultaneous usage of multiple paths for a single connection. The extension is compliant with the single-path QUIC design. The design principle is to support multipath by adding limited extension to [QUIC-TRANSPORT].
