A Fair Algorithm of Congestion Control to Improve HSTCP

Standard TCP has lots of problems; for example, the network bandwidth can not give its full play in certain application conditions such as high speed or long distance. High Speed TCP (HSTCP) can solve these problems, but it has serious problems in the fairness of different RTT. Based on the analysis of HSTCP fairness, an algorithm of adding fair factors to improve fairness of HSTCP has been put forward after fairness simulation test by NS2. NS2 simulation experiments prove that this algorithm has greatly reduced the unfairness because of the different RTT.
