[0045] Combine Figure 1 to 3 Further, for further explanation of the invention:
[0046] Step 1: Build a network model. The network architecture of the present invention is like figure 1 As shown, the idea of software-defined satellite network is implemented for double satellite architecture. The software defined satellite network mainly includes three types of controllers, switches, and terminal hosts, forms a three-layer architecture from the top.
[0047] The specific function design of the three types of nodes contains the following:
[0048] Controller: GEO Satellite As the controller, 3 GEO satellite groups into distributed controllers, responsible for collecting satellite data and link data of each LEO switch node, and sending the corresponding stream table items based on pre-configured control management strategies LEO satellite.
[0049] Switch: The LEO satellite acts as a switching node, connected to the ground terminal, the Iridium constellation of 66 Leo as the data ...
