Application Discussion of Software Defined Network in Space-based Information Network
摘要
Abstract
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.关键词
