Multimedia-Aware Congestion Control for Video Streaming over the Internet

This paper presents congestion control protocols designed for use in video applications over the Internet. Such protocols should take video traffic characteristics into account while behaving in a friendly manner with respect to competing flows in the Internet. Building on the TEAR protocol, additional video traffic characteristics are taken into account by considering flows with variable packet sizes, a characteristic of video traffic due to the packetization and error-control schemes of video coding systems. Our experiments show our proposed protocols take more video traffic characteristics into account than TEAR while maintaining TEAR´s TCP-friendliness.
