Many use cases seem to suggest reasons to bring back coding in QUIC.

Here is a comprehensive presentation that includes most of the aspects I
mentioned:

Hello,

in case you missed it, the MOQ (Media over QUIC,
https://datatracker.ietf.org/meeting/113/materials/agenda-113-moq-06) BOF
at IETF-113 is discussing low-latency video distribution use cases.

The idea is to reduce latency for live streaming, i.e., achieving
interactive conferencing latency without losing scalability.

The current thinking is using either RUSH (
https://datatracker.ietf.org/doc/html/draft-kpugin-rush-00) or SRT over
QUIC (meh ;-).

I believe that eventual solutions will have to do with stream
prioritization, "relaxed" congestion control and incorporating the concept
of relays.

Other topics/ideas that came up:

   - application layer multicast
   - local retransmissions
   - content naming

Maybe something to look into from an ICN perspective...

Dirk
