Abstract: Methods for proxy-driven content rate selection for streaming media servers are provided. In one method, one or more maximum transmission rate parameters from a network controller are stored at a proxy server in response to a receiver report message from the client. A target rate for the media session is generated based on the stored maximum transmission rate parameters, and the target rate is transmitted to a media server in a proxy-to-server feedback message. The media server selects the content rate from among a plurality of supported content rates in response to the proxy-to-server feedback message from the proxy server, and streams streaming multimedia frames to the client at the selected content rate.

Abstract: In a method for dynamically setting a content rate of a multimedia session for a client in a network, a proxy server receives a channel condition feedback message from a network controller and determines whether a receiver report message has been received from the client since a most recent previous channel condition feedback message. The channel condition feedback message includes current channel condition information for the network. The proxy server sends one of an extended feedback report message and a short feedback report message to a media server based on the determining step. The short feedback report message includes at least a maximum transmission rate parameter for the multimedia session. The extended feedback report message includes at least information contained in the receiver report message. The extended feedback report message may, in addition, include the maximum transmission rate parameter for the multimedia session.
