摘要:
该文分析了低轨卫星网络中TCP报文盲目重传的原因,采用预切换方法,提出了避免了报文盲目重传路由策略。采用OPNET仿真软件对改进的策略进行了仿真,结果表明:提出的路由策略能够有效避免LEO卫星网络中数据包盲目重传,改善了TCP连接性能,并且与地面Internet网络具有很好的兼容性。
Abstract:
The handoff in LEO satellite networksmakesTCP protocol retransm it packet blindly, and decline TCP performance. The reasons of retransm itting packet blindly are analyzed. A pre-handoff method is used and an algorithm of routing isproposed to avoid the packet being retransm itted blind- ly. The simulated resultsbyOPNET indicate that the algorithm can efficiently avoid the packet being retransm itted blindly and improve the perform ance of TCP. Themethod has good compatibility w ith the Internet on the terrestrial network.
