摘要:

空间延迟容忍网络(DTN)架构通过“存储—携带—转发”等功能可以有效地支持具有长时延、高误码率、链路频繁通断等特性的深空通信网络。由于深空通信方面应用的实验不易搭载测试,于是,搭建准确可信的半物理仿真平台对深空通信任务的设计进行仿真论证是非常必要的。提出了支持各种特定的深空通信任务仿真的空间DTN半物理仿真平台。本仿真平台为深空通信新理论、技术等提供地面仿真与验证,为开展深空通信应用研究提供了分析工具以及测试手段。

Abstract:

The architecture of space delay tolerant networking can effectively support a deep space communication network with long delay,high error rate and on-off frequently link characteristics through“store-carry-forwards”and other features.Due to the experiment of application of deep space communication is not easy to carry,so building an accurate and reliable semi-physical simulation platform for simulating and making an argumentation of the design of deep space communication tasks was very necessary.A space DTN semi-physical simulation platform was proposed which supported a variety of specific deep space communication tasks simulation.The simulation platform provided new theory and technology for ground simulation and verification,and provided analysis tools and test instruments for carrying out deep space communication application study.

Key words: delay tolerant network, deep space communication, semi-physical simulation platform, SDN
