一种基于伽玛分布的TCP拥塞控制算法

A TCP congestion control algorithm based on gamma distribution

基于伽玛分布函数,提出了运用新的拥塞控制算法判断网络状况,提前预估拥塞窗口开启大小,从而改善系统性能,并对新算法的合理性和可行性进行理论分析和论证,估算了多个参数值.仿真结果表明:新算法可有效增大拥塞窗口值,降低丢包率,对系统吞吐量及带宽利用率的提升也有一定帮助.

Based on the gamma distribution function,this paper proposes a new congestion control algorithm to determine the network condition and forcast the size of the congestion window.The rationality and feasibility of the new algorithm are analyzed and demonstrated theoretically and multiple parameters are estimated.The simulation results show that the new algorithm can effectively increase the congestion window,reduce packet loss rate,and improve the system throughput and bandwidth utilization.
