 Simulcast in WebRTC allows a single video source, like a camera or screen share, to be encoded at multiple quality levels and sent simultaneously, which is beneficial for subscribers with varying network conditions and device capabilities. The video source is encoded into multiple streams, each identified by RIDs (RTP Stream Identifiers) for different quality levels, such as low, medium, and high. These simulcast streams are described in the SDP you send to Cloudflare Realtime SFU. It's the responsibility of the Cloudflare Realtime SFU to ensure that the appropriate quality stream is delivered to each subscriber based on their network conditions and device capabilities.
 
-Cloudflare Realtime SFU will automatically handle the simulcast configuration based on the SDP you send to it from the publisher. The SFU will then automatically switch between the different quality levels based on the subscriber's network conditions, or the qaulity level can be controlled manually via the API. You can control the quality switching behavior using the `simulcast` configuration object when you send an API call to start pulling a remote track.
