摘要
空间链路高误码、长延时、断续连接等特性导致TCP性能严重下降。空间通信传输协议SCPS-TP是针对空间链路特点量身定制的传输层协议。通过对SCPS-TP进行仿真分析来评估SCPS-TP的在空间链路上的传输性能,并详细分析了SCPS-TP在TCP基础上的改进之处,对SCPS-TP和TCP的传输性能进行仿真和比较分析,仿真结果表明在高延时高误码的空间链路上SCPS-TP传输性能优于TCP。
Being an extended protocol based on TCP, Space Communication Protocol Standards-Transport Protocol (SCPS-TP) is tailored to address the problems of space links to provide a more reliable data transfer . The improvements of SCPS-TP over TCP are analyzed. Comparison of SCPS-TP and TCP in their transferring capability show that SCPS-TP has significant throughput advantages over TCP.
