Hi Everyone,
We submitted a new draft version -15 for multipath extension: https://datatracker.ietf.org/doc/draft-ietf-quic-multipath/ This version contains several modifications regarding to review comments during the last call: 1. Rename PATH_AVAILABLE and PATH_BACKUP frames to PATH_STATUS_AVAILABLE and PATH_STATUS_BACKUP frames. 2. Connection closure follows RFC 9000. Considering closing and draining connection states "SHOULD persist for at least three times the current PTO", please use the largest PTO among all paths. 3. If an endpoint sends a PATH_RESPONSE, it MUST be sent on the same path as used by the packet that contained the PATH_CHALLENGE frame, using a connection ID associated with the same path ID. 4. Fix the example of new path establishment and AEAD nonce calculation. 5. Rename transport error codes used in the PATH_ABANDON frame. 6. It’s not recommend to send keep-alives as it can create unnecessary overhead, especially if there’re other actively used paths. 7. In the Section of Security Consideration, express the risk of amplifired DoS attack with Multiple Paths and how to limit it. 8. Other small editorial modification.
