As the Internet evolves to include wide-area high bandwidth network paths, it has become possible to provide high volume multimedia applications over the Internet. However, slow-start based congestion control schemes have several limitations to guarantee the quality of high volume multimedia applications over high bandwidth networks. Slow-start mechanism requires many RTTs until an appropriate transmission rate is reached. This time-consuming process disturbs the rapid increase in video quality. Another problem of previous congestion control mechanism is burst packet losses caused by overshooting of transmission rate. These burst packet losses degrade the quality of video. In this paper, we propose a congestion control scheme to improve the quality of high volume multimedia streaming over the high bandwidth networks. The proposed scheme increases congestion window based on the enhanced cubic function and the bandwidth estimation scheme to support fast start of flows. Also, our scheme reduces packet losses by mitigating overshooting of transmission rate. Simulation results have shown that our proposal can achieve a fast start up and reduce packet losses compared to the previous congestion control scheme for high bandwidth delay product networks.
