The section is about data channels, which uses SCTP and is ACK-based. Yes, you can use RTP with NACK and/or FEC with the media stack, but not with the data stack.
- the8472 3y agoTCP can coalesce acks for multiple packets, can't SCTP do the same?
- Sean-Der 3y agoSCTP can (and does) a SACK[0] isn't needed for each DATA chunk. [0] https://datatracker.ietf.org/doc/html/rfc4960#section-3.3.4 https://datatracker.ietf.org/doc/html/rfc4960#section-3.3.4
- kixelated 3y agoThe protocol can do it, but libsctp (used by browsers) was not coalescing ACKs. I'm not sure if it has been fixed yet.
