Vol. 9  No. 3  pp. 254-261


Congestion control for streamed media traffic over Internet is a challenge due to the sensitivity of such traffic towards oscillations in the rate of streaming. This challenge motivated researchers over the last decade to develop a number of congestion control protocols that suit the media traffic and provides TCP-friendliness for both unicast and multicast communications. This paper presents a discussion for the congestion control protocols categorization characteristics, elaborates the TCP-friendliness concept then a state-of-the-art for the unicast congestion control protocols designed for media traffic is presented. The paper points the pros and cons for each of these protocols, and evaluates their algorithms characteristics.
