摘要 针对当前网络拥塞控制算法在极小缓存高速网络中带宽利用率差的问题,研究了TCP机制本身造成的突发流量现象,提出一种新的拥塞控制算法——PSTCP。在整个网络连接过程中,该算法采用"隔开"平滑发送的思想;在网络拥塞发生时,采用公平因子c和减少因子decrement对窗口进行实时微调。实验表明,PSTCP在小缓存区、高带宽网络环境下,保障了高的带宽利用率,有好的收敛性和公平性。 Focusing on the poor bandwidth utilization phenomenon of the current network congestion algorithm for small buffer in high speed network,the phenomenon of TCP mechanisms cause burstiness is studied,a new congestion control algorithm,PSTCP is proposed.Throughout the network connection process,the algorithm uses the"separatedi"dea of smoothing to sending,in the network congestion occurs,the sending window size is adjusted dynamically by changing the values of fair factor and reduction factor.Experiments show that PSTCP in a small buffer networks environment protects high bandwidth utilizationa,nd has good convergence and fairness.
