【摘要】 针对TCP Vegas会出现慢启动过早结束、拥塞窗口过小导致带宽利用率下降的问题,以及在与Reno等基于丢包来判断拥塞的算法竞争带宽时的公平性差等问题,文中分别就慢启动和拥塞避免阶段进行了相应的改进,最后将其结合.仿真结果表明,该算法对慢启动过早结束、带宽公平性等TCP Vegas协议的缺陷有了明显的改善,特别是在高带宽时延乘积网络中.更多还原

【Abstract】 TCP Vegas to change from slow-start phase to congestion avoidance phase too early,and congestion window is too small resulting in bandwidth utilization is dropping,and so on with Reno congestion based on packet loss to determine when the algorithm competitive bandwidth resulting in fairness badly.The paper on the slow start and congestion avoidance phases corresponding improvement,and finally to combine.By the simulation results show that the slow start algorithm too early end and bandwidth fairness of TCP Vegas,such as defects in agreement with the marked improvement,especially in the high-bandwidth delay product networks.更多还原
