摘　　要：现有各种空间、地面网络节点的互连互通,在一定程度上可满足特定应用需求,但由于各节点在空间、物理以及功能的局限,限制了天基信息高效传输、融合以及按需地应用。分析了天基信息网络的发展趋势,提出了网络架构构想,并对主要关键技术的研究方向进行了梳理。在空间核心节点上采用软件定义的多功能载荷平台,并基于软件定义网络(SDN)架构和空间容中断网络协议构建天基信息网络。通过资源虚拟化、处理多元化、应用无阻化的方式,保障天基信息网络适应信息按需定制和高效共享等应用需求。The interconnection of the existing space-ground network nodes can satisfy the specific need of the space-ground information network application to a certain extent. However,due to the limitation of the space,physics and function of the nodes,effectively transmitting,combining and on-demand applying the space-based information is restricted. In this paper,the developing trend of the space-based network is analyzed. A conception of the network is discussed. The research trend of the key technologies is com-piled. In addition,it is proposed that the space-based information network may be constructed by the load platform of multiple functions defined by the software on the space core nodes,the architecture of the soft-ware defined network(SDN) and the space delay-tolerant network(DTN) protocols. And then,the re-source virtualization,the process diversification and the application intelligence of the network may be a-chieved. In the future,the network will satisfy the application requirement of information customization and efficiently sharing etc.
