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.
