Abstract
A technique for selecting a media streaming engine, such as a stream server, to source a media stream to a client involves receiving feedback information from a client that indicates a quality of service experienced by the client and then selecting a media streaming engine, from a set of media streaming engines, in response to the feedback information. In an embodiment, the feedback information is provided in Real-Time Control Protocol (RTCP) messages. For example, the RTCP messages are Receiver Report (RR) messages that contain packet loss and/or inter-arrival jitter information. Feedback information such as packet loss and/or inter-arrival jitter information represents the actual quality of service experienced by a client for a media stream. Because a media streaming engine is selected based on the actual quality of service experienced by a client, the selection process can be configured to optimize the quality of service of the media streaming.
