摘要
针对深空通信面临的各种问题,对当前深空通信中常用的三种网络协议体系进行了简要介绍,并在此基础上对比三者优缺点,提出其各自的适应场景;阐述了未来深空通信网络面临的困难与挑战;剖析容迟容断网络体系架构,并介绍了DTN网络应用研究进展;列举深空通信网络DTN协议体系中的关键技术,例举在深空环境中使用DTN协议体系进行通信时面临的诸多问题,并展望未来深空通信中DTN的应用前景。
This paper introduces briefly three network protocol architectures used in deep space communication,compares the advantages and disadvantages of these three architectures,and proposes the application scenarios of all three architectures based on the analysis of the challenges and existing problems in the deep space communication.Subsequently,this paper dissects the architecture and analyzes the study progress of DTN. Meanwhile the key techniques of DTN protocol architecture are introduced,and the problems in communications using DTN protocol architecture in deep space environment are discussed. The application prospect of DTN in future deep space communications is envisioned.
