| 摘 要： | 给出了在实际卫星链路环境中分别使用空间通信协议标准-传输协议（Space Com-munication Protocol Standard-Transport Protocol,SCPS-TP）、TCP Hybla协议和性能增强代理网关技术（PEPsal）的链路传输速率,并对结果进行了分析和比较,表明SCPS-TP协议在高丢包率、长传输时延的卫星链路中性能最优越;提出了一种基于SCPS-TP协议的空间网络传输层加速方法改进思路,通过增加新的更具针对性的改进型拥塞控制策略,克服其原有的保守型窗口增长模式的缺点以提高链路平均吞吐量。

| Abstract: | The paper shows the transport rate on a real satellite link when Space Communication Protocol Standard-Transport Protocol （SCPS-TP）,TCP Hybla protocol and PEPsal technology is used separately,with some analysis and contrast followed,and the results indicate the SCPS-TP performed the best on satellite link with high packet loss rate and long transmission delay. The paper also put forward an improvement idea of transport protocol acceleration of space internet based on SCPS-TP,to increase its average throughput,via adding a new and more pertinent improved congestion control strategy which can overcome its intrinsic conservative congestion window increase mode. |
