Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0024] This embodiment discloses an adaptive software-defined space-ground integrated network system, such as figure 1 As shown in the schematic diagram of the architecture, Figure 1 An example software-defined network (SDN) when the number of satellites in the low-orbit satellite (LEO) is three, medium-orbit satellite (MEO) three, high-orbit satellite (GEO) three, ground network center four, and of course, This system is scalable to any number of satellite and terrestrial hubs, and the software-defined network (SDN) separates the control and data planes.
[0025] The number of low-orbit satellites (LEO) is set to at least three; the number of medium-orbit satellites (MEO) is set to at least three; the number of high-orbit satellites (GEO) is set to at least three.
[0026] The control plane includes the controller in the high-orbit satellite (GEO), which ...
