摘　　要：TCP/IP发展迅猛,卫星信道承载TCP/IP业务势在必行。卫星信道具有长时延特性,而TCP是一种基于连接的互联网协议,分组传输需要确认,从而给卫星信道传输TCP业务带来效率低下的问题。卫星信道传输TCP分组的速度受限于延时,而不是取决于信道速率。采用TCP协议欺骗的方法可以有效提高卫星信道传输速率,进而提高卫星信道利用效率,最终达到有效解决延时限制信道的问题。With the rapid development of TCP/IP, the trend of satellite channel carrying TCP/IP data is imperative. Satellite channels have the characteristics of long delay, while the TCP is a internet protocol based on connecting, packet transmission need to be confirmed, resulting in the low effeiency problems of TCP transmission over the satellite channel. The speed of transmitting of TCP packet over the satellite channel is limited to delay, rather than depending on the satellite channel rate. By using the method of TCP spoofing,the speed of transmission TCP over the satellite channel and the utilization efficiency of satellite channel can effectively be improved, and the problem of channel delay constraints can be solved effectively.
