摘要： 针对H-TCP存在的RTT公平性和TCP友好性不好的缺点,提出了一种基于H-TCP的拥塞控制改进算法RH-TCP。NS-2模拟实验结果表明,RH-TCP明显提高了RTT公平性和TCP友好性,并且保留了良好的带宽利用率、稳定性、收敛性和公平性,在6个新TCP协议中RH-TCP的总体性能最好。

Abstract: As H-TCP is short of RTT fairness and TCP-friendly,we present an improved algorithm RH-TCP for congestion control based on H-TCP.The result of NS-2 simulation experiments shows that RH-TCP advances in RTT fairness and TCP-friendly obviously,and keeps good bandwidth utility,stability,convergence and fairness.RH-TCP has generally the best performances among the six new TCP protocols.
