摘要： 空间数据系统咨询委员会(CCSDS)针对空间通信的特点制定了空间通信协议标准SCPS(Space Communications Protocal Specification)。文章从CCSDS标准在中国空间技术的实际应用出发,对CCSDS SCPS协议中网络层协议(NP)和传输层协议(TP)进行研究,分析其特点和适用性,并与TCP/IP协议进行对比,最后设计演示验证系统对所提方案进行验证并得出结论:在空间通信环境下,采用SCPS协议后的性能优于采用TCP/IP协议。

Abstract: According to the characteristics of space communications,the Consultative Committee for Space Data Systems(CCSDS)developed SCPS(Space Communications Protocal Specification) protocol set.The application of CCSDS recommendations in China,and the practical application of CCSDS SCPS protocol in network layer(SCPS-NP) and Transport Protocol(SCPS-TP) were introduced,characteristics and applicability were analyzed.It was also compared with TCP/IP protocol for contrast,finally design the program verification system to verify the proposal.The results show that for space communications in specific circumstances,the use of SCPS protocol is superior to that of TCP/IP protocol.
