| 摘 要： | STCP(ScalableTCP)算法是个典型的积式增加积式减少的适合高速网络的拥塞控制算法。该算法具有很高的吞吐量,但是RTT公平性和TCP友好性较差。提出一种改进的STCP算法,简称NSTCP,通过添加公平因子,减轻了RTT不公平性;通过估计当前网络带宽、调整高速TCP和传统TCP的转换模式提高了算法的友好性。仿真实验证明NSTCP算法提高了这两个方面的性能。

| Abstract: | Scalable TCP algorithm,STCP for short,is a typical Multiplicative Increase Multiplicative Decrease congestion control algorithm suitable for high speed network.STCP has high throughput but is short in RTT fairness and TCP-friendly.In this paper it proposes a modified STCP algorithm,called NSTCP.NSTCP improves the RTT fairness by adding a fairness factor,and improves TCP-friendly by estimating the bandwidth of current network and adjusting the switching mode between traditional TCP andhigh speed TCP.The simu... |
