| 摘 要： | 为了提高TCP协议在卫星链路上的性能,对传统的TCP协议进行了两点改进:增大慢启动算法的初始窗口;改进窗口增长算法.利用计算机仿真详细地研究了改进的TCP协议在卫星连路上的性能.仿真结果表明,相对于传统的TCP,改进的TCP协议的吞吐率显著提高,体现了更优越的性能.

| Abstract: | To improve performance of TCP on a satellite link,two aspects of modification are made based on the traditional TCP: 1)enlarging initial window of the slow start;2)modifying the window scale algorithm.Performance of the improved TCP on a satellite link is studied detailedly by computer simulation.Simulation results showed that throughput of the improved TCP is dramatically heightened and more excellent performance is exhibited in contrast to the traditional TCP. |

| Keywords: | satellite TCP slow start window scale algorithm throughput |
