Description

WebRTC senders

are REQUIRED to implement support for TMMBR messages, and MUST follow
bandwidth limitations set by a TMMBR message received for their SSRC.
The sending of TMMBR requests is OPTIONAL.

[BA] I realize I'm opening a can of worms here, but what does it mean to "follow bandwidth limitations set by a TMMBR message"? Is this mandating support for a receiver-side congestion control mechanism? Or is it considered more like advice from the receiver on average bandwidth availability over some time period (e.g. averaged over I and P frames)? Or is this a maximum simultaneous bw limitation?
