Efficient transmission of delay-stringent video over the Internet is examined in this work. In our design, an end user adjusts the network load depending on the perceived network status to satisfy the available bandwidth and the individual loss rate requirement while exhibiting network friendly behavior. In particular, we present a model-free, receiver-based congestion control mechanism that bypasses Internet modeling difficulties and yet is capable of feeding back the current network status in accurately and timely manner. Through efficient reaction to network dynamics, the proposed congestion control scheme exhibits fast convergence to the optimal bandwidth, while maintaining fairness with other data streams.
