Abstract
A distributed and scalable content streaming architecture includes a plurality of controllers and a plurality of servers. The controllers are operable to establish Real-Time Streaming Protocol (RTSP) sessions with individual devices. A controller selects a server to provide a requested media stream to a device. The server may be selected based on its proximity to the device, bandwidth availability, or latency characteristics. The server transmits the media stream using a Real-Time Transport Protocol (RTP) and/or a Real-Time Control Protocol (RTCP). A controller can manage a number of sessions many times greater than the number of streams a server can provide, so a controller typically has access to multiple servers. Additional servers can be added to a system without disrupting system operation.
