摘要
针对空间数据传输与交互支持问题,介绍了CCSDS(Consultative Committee for Space Data Systems,空间数据系统咨询委员会)、IOAG/IOP(Interagency Operations Advisory Group/InterOperability Plenary,机构间操作指导组/机构间互操作大会),以及IETF/IRTF(Internet Engineering Task Force/Internet Research Task Force,互联网工程任务组/互联网研究任务组)在空间网络体系架构方面的研究进展,分析了IETF和CCSDS针对空间网络环境所发布的最新网络层协议和传输层协议。研究结果表明,IP(Internet Protocol,互联网协议)和DTN(Delay Tolerant Networking,容延迟网络)是空间网络协议体系的2个发展方向,而空间网络技术则呈现出3个清晰的发展趋势,现阶段需要重点关注路由、服务质量保证和数据流传输这3个方面的技术问题。
The development of research on the architecture of space network by CCSDS（Consultative Committee for Space Data Systems）,IOAG（Interagency Operations Advisory Group）,IOP（InterOperability Plenary）,IETF（Internet Engineering Task Force）,and IRTF（Internet Research Task Force）are introduced with respect to space data transmission and cross support of space missions.Evolving technologies of network layer and transport layer protocols in IETF and CCSDS are analyzed.The analysis clearly shows two developing directions of space network protocol systems,i.e.IP（Internet Protocol）system and DTN（Delay Tolerant Networking）protocol system.Three developing trends and key technical issues such as routing,QoS（Quality of Service）and streaming data transmission are identified and they should be highlighted at present.
