Hi Everyone,
We submitted a new draft version -12 for multipath extension:
https://datatracker.ietf.org/doc/draft-ietf-quic-multipath/
<https://datatracker.ietf.org/doc/draft-ietf-quic-multipath/ >
The new version contains several modifications:
1. Add PATH_CIDS_BLOCKED frame as an explicit signal for situations when
endpoints don’t have unused CIDs for the corresponding path
2. When endpoint sends PATH_ABANDON frame but don’t receive a corresponding
PATH_ABANDON, it’s left to the implementation when to release the path
resources, but endpoints SHOULD wait at least 3 PTOs before remove the issued
CIDs of the path.
3. Packets which only contains PATH_ACK frames are not congestion controlled,
but senders should carefully consider the load induced by these packets.
4. Add guidance for handling PTO on multiple paths.
5. It’s recommended to open a new path for active client migration.
6. Update transport parameter for the new version.
