4.9 Receiver-side Bandwidth Limit

When a host is sending application sharing payload to a mixer the mixer can request that less payload is sent to the mixer. The following describes how the mixer does this.

Figure 15: Message exchange for receiver-side bandwidth limit

Host 1 is sending an application sharing payload (as described in [MS-RTASPF] section 3.2.5) to the mixer at a bitrate more than 500 kbps. The mixer determines that it cannot handle the incoming stream from Host1 at this bitrate and asks the Host1 to send the stream at 500 kbps or lower bitrate by sending the RTCP packet with a receiver-side bandwidth limit extension to Host1. Upon receiving the extension, Host1 caps the outgoing stream to 500 kbps.
