摘要
容延迟网络(DTN)体系结构依靠一种新的严格的框架,能够集成深空环境异构网络技术,为解决深空通信面临的许多重要问题提供了有效解决途径。分析了未来深空通信网络面临的难题;阐述了深空通信网络协议的研究现状;深入剖析了DTN体系结构,并从研究和项目两个层面详细介绍了深空通信DTN研究进展;讨论了深空通信中应用DTN的一些关键技术问题,并分析了DTN在我国未来深空测控通信的应用前景。
The Delay/Disruption Tolerant Network(DTN) architectures technique which can integrate some disparate deep-space environment networks by one new rigorous framework provides effective solution for some important issues that face the deep space communications.Some issues on future deep-space communication network are studied,and the research developments on deepspace communications network protocols are depicted.After deep research on DTN architectures,the application of DTN for deep space communication is introduced in detail.Some critical problems of the application of DTN and prospects for application of future deep-space in our country are analyzed.
