| 摘 要： | 卫星信道与地面有线信道具有不同的特点,当TCP协议直接应用于卫星链路上时,其吞吐量等性能会受到影响。针对卫星链路的特点,分析了现有的卫星链路进行TCP传输的几种解决方案,使用NS 2仿真软件,建立了仿真模型,并在给定的仿真环境下得出了一些卫星链路下TCP传输性能和卫星spoofing技术的仿真结论。卫星链路具有时延大、误码率高等特点,仿真结果说明卫星spoofing技术和PS技术相结合的方案对卫星链路TCP传输性能改善是十分有益的。

| Abstract: | Because satellite channel and terrestrial cable channel has different characteristics,when the TCP is used in a satellite link directly,the performance such as its throughput will be affected.According to the satellite link characteristics,the several main solutions of the TCP transmission in the available satellite links are analyzed,the simulation models are established with the simulation software of NS2,and simulation conclusions about the TCP transmission performance in satellite links and satellite-sp... |
