摘    要:现有TCP慢启动机制中拥塞窗口的指数增长,会导致在慢启动后期一个窗口中出现多个包丢失的现象。提出了一种基于比例的慢启动改进算法一CS Slow_Start。谊算法实现了从慢启动到拥塞避免的平滑过渡,减少了在一个窗口中出现多个包丢失的现象。试验表明,新算法能明显减少丢包数和数据突发量,提高了网络的稳定性。

关 键 词:TCP  拥塞控制  慢启动

Abstract:Current implementations of the TCP Slow_Start mechanism's exponential growth of congestion window,results in many packets drops from a window of data.This paper presents a improvement to the TCP Slow Start,which called CS Slow_Start.This algorithm provides a smooth transition between the Slow-Start and Congestion Avoidance,which avoids drop multiple packets from a window.Experiments indicate that the improved algorithm can reduce the dropped packets and abrupt data,enhance the stabilization of network.
Keywords:TCP   congestion control  Slow-Start
