基于Mesh的空间信息网体系结构研究

Research on Mesh-Based Architecture for Space Information Network

在高动态的拓扑结构和不连续的链路状况下进行资源的有效配置以及可靠的低延时数据传输,是进行空间组网通信时面对的两大挑战。在深入分析空间信息网络特点和功能需求的基础上,提出一种基于Mesh结构的空间信息网络体系结构,对采用Mesh结构在空间组网通信中的优势进行了深入的剖析,并给出了空间信息网络协议架构模型。结合空间信息网络的特点分析了进行空间组网通信亟待解决的关键技术及其解决思路。对空间信息网络的进一步研究有一定的参考价值。

The space communication networking faces two challenges, which are efficient resource allocation in a highly dynamic topology of intermittent link end reliable low - latency data delivery. Based on the thorough analyzing of characteristics and functional requirements of space information network, a new mesh- based architecture for space information network was proposed, and the advantage of space communication networking based on mesh structure was also analyzed. Further more, the protocols structure of space information network was presented. Finally, the key technologies of the space information network were discussed with the structure and characteristics of the space information network, and some possible resolutions are also given. It will provide references for further research on the space information network.
