I read this article(https://webrtchacks.com/sfu-simulcast/) , and it mentions
In most cases SFUs were just forwarding RTCP feedback from all receivers to the sender. As a result, senders would adapt bitrate to the worst receiver conditions (i.e. lowest estimated bandwidth and worst network QoS) which would then be forwarded to all participants.
And I want to know if licode forwards all RTCP feedback(especially REMB)from all receivers to the sender.
