摘要
The Space Information Network (SIN) is a full-spatial, full-time, full-frequency, multi-users-oriented information network which has the characteristics of complexity, heterogeneous, and openness. In this paper, we propose a software-defined space information network (SDSIN) to solve above-mentioned problems. This architecture based on the core idea of Software-Defined Network (SDN) that separate control and forwarding panel, and takes full use of the global coverage properties of Geostationary Orbit (GEO), powerful computing capacity of ground station, the predictability and regularity of constellation and the forwarding capacity of inner-satellite links (ISLs). Thus the network can allocate and optimize network resources from a global perspective so as to achieve flexible and efficient network configuration and management, and realize direct and effective control of spatial information network.
