Hi multicast-cg, Tomorrow's meeting will be at 4:30pm UTC (9:30am Pacific time), I hope to see you then. Proposed agenda: - 5 min: welcome and agenda-bash - 30-45 min: Status update & discussion - We had another productive month. Max, Leo, Kyle, and I continued some decent work toward a demo of the proposed multicast extension for quic. You can follow our progress here: implementation: https://github.com/GrumpyOldTroll/quiche spec: https://github.com/GrumpyOldTroll/draft-jholland-quic-multicast - noticed a new problem last week with webtransport (if we could have a server-chosen session id, we could use our multicast channels for webtransport server-initiated streams, but without it I think we'll have trouble. (Same problem with http-datagrams, which webtransport uses by reference.). See sections 2.3 and 4.1 of webtransport-02: https://www.ietf.org/archive/id/draft-ietf-webtrans-http3-02.html#section-4.1 - So I think this month we'll want to update the spec one more time in the IETF datatracker and reach out to at least the msec list and probably the webtransport list to see if there's any reasonable way to make the session ids server-chosen values so they can be used for multicast. (Another alternative would be to make them fit in a fixed- size block that can be sent in the unicast connection, with the stream data then going in the multicast channel at a later offset. Less efficient but at least possible. But the way it is now with a variable length ID chosen by client, it's hard to see how it can be made to work.) - 10 min: Next Steps See you tomorrow. Jake PS: last month's meeting notes and recording are posted, I think I forgot to send out an update when they went up, sorry: https://github.com/w3c/multicast-cg/tree/main/meetings ----- Meeting coordinates: Monthly Multicast W3C Community Group Meeting Hosted by Jake Holland https://akamai.webex.com/akamai/j.php?MTID=m46e51f96f443eda24eed93ad804cb8df Wednesday, Jun 1, 2022 9:30 am | 1 hour | (UTC-07:00) Pacific Time (US & Canada) Occurs the first Wednesday of every month effective 1/5/2022 from 9:30 AM to 10:30 AM, (UTC-07:00) Pacific Time (US & Canada) Meeting number: 145 142 6461 Password: yay-multicast!
