摘要
进一步发展Internet业务需要增大带宽并且要有移动性,因而卫星网与IP网结合成了热门话题.针对卫星网的信道差错率高、传播延迟长和信道不对称性对TCP传播性能有不良影响,介绍了前向纠错和自动重传两种链路差错控制方案和对TCP的改进.
In order to increase band width and improve mobility of internet traffic,the people tryg to construct internet over satellity.Due to the high BER,much delay and channel asymmetry of satellite network,the performance of TCP is not perfect.In this article,we introduce FEC scheme and ARQ schemes to improve TCP.
