OpenFlow based spatial information network architecture

Space-ground integrative information network is an effective method to realize the global coverage of information, and the efficient use of information and communication resources. In the face of the current situation of the space information network considered for specific and military purposes, as well as the characteristics of the closed and rigid, it becomes an urgent problem that how to realize the information service of space-ground integrative and military-civilian integrative. This paper presents OpenFlow based spatial information network architecture. Firstly, the basic framework of Space-ground integrative network is introduced in detail. Secondly, the key technologies such as spatial physical resource management strategy, virtual spatial network management strategy and virtual spatial network slice management strategy, spatial application management strategy are designed in detail. This structure can realize the flexible control of the space information network, the integration of the fusion, the open programmable and the flexibility of the space information network.
