Study on Internet Congestion Control Algorithm

With the continuous expanding of Internet scale, the network users and application increase rapidly and congestion control has become focus of network study. Several congestion control algorithms have been proposed out and improved for effective reduction of packet loss rate and for better utilization of network bandwidth. After analysis of several reasons causing network congestion, this paper presents detailed analysis and comparison of source algorithm, link algorithm and high-speed network congestion control algorithm, and further discusses the future research direction.
