摘　　要：静地轨道卫星通信由于经历长远距离的传输会经历长时延的影响,对卫星通信网络数据的传输有非常大的影响。传统的TCP协议不能很好的适应卫星网络的传输,该文对几种TCP协议,TCP Reno,TCP Veno,TCP ADa LR和其改进的算法进行了对比,并在OPNET软件上进行了仿真,实验仿真表明在卫星链路上可以通过增加数据的发送量来提高网络的性能,还可以通过对数据包的丢失的检测来选择合适的阈值。Geostationary orbit satellite communication transmission has very big effect to network performance because the long delay.The traditional TCP protocol is not suitable for the transmission of satellite network,in this paper,based on several TCP protocols,such as TCP Reno,TCP Veno,TCP ADaLR and its improved algorithm,and simulation is made in OPNET software,simulation experiments show that the satellite communication link can improve network performance by increasing the amount of data transmission,can also according to the detec- tion of missing packets to select the appropriate threshold.
