The best-effort service model of the Internet is unsuitable for streaming applications which require a smooth and flexible packet transmission rate. TCP is unable to provide such a sending rate due to its strict adherence to congestion control. We study the effect of the transport protocolpsilas send buffer size on the performance of streaming media and propose a dynamic send buffer tuning approach which also provides congestion feedback to the application. Simulation results show that this technique improves streaming performance.
