    Abstract: A method and apparatuses for rate control of a multi-quality data stream using multiple, combined probing techniques includes receiving a multi-quality data stream, adding padding packets to the multi-quality data stream to determine which data stream of the multi-quality data stream to select to communicate data packets of the multi-quality data stream, adding probing packets to the selected data stream of the multi-quality data stream to determine a bandwidth at which to communicate the selected data stream, and communicating the selected data stream to receivers using the determined bandwidth. In some embodiments, the method and apparatus can further include determining whether or not a different quality data stream of the multi-quality data stream should be selected before adding padding packets to the multi-quality data stream and/or determining if a bandwidth estimation process should be performed before adding probing packets to the selected data stream of the multi-quality data.

    Abstract: A method and apparatuses for full sender-side rate control include receiving a data stream at a forwarding unit, determining a bandwidth estimation for communicating the data stream between the forwarding unit and a sender of the data stream, determining respective bandwidth estimations for communicating the data stream between the forwarding unit and at least two receivers, aggregating the bandwidth estimations determined for communicating the data stream between the forwarding unit and the at least two receivers, and limiting the bandwidth estimation determined for communicating the data stream between the forwarding unit and the sender of the data stream based on the aggregated bandwidth estimations. In some embodiments, the bandwidth estimation determined for communicating the data stream between the forwarding unit and the sender of the data stream is limited by communicating a limitation message regarding the aggregated bandwidth estimation of the receivers to the sender.
