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 ...

Abstract

The invention discloses a self-adaptive software-defined space-ground integrated network system. According to the technical scheme, the self-adaptive software-defined space-ground integrated network system is characterized by comprising a ground data center and a space part; the space part comprises a low earth orbit satellite (LEO), a medium earth orbit satellite (MEO) and a high earth orbit satellite (GEO); the system also comprises a software defined network (SDN). The software defined network (SDN) separates a control plane from a data plane, is suitable for multi-level satellites adoptingLEOMEOGEO architecture, is suitable for more types of constellations (satellite systems), such as Iridium constellations, compared with the design in the prior art, the system is better in universality. According to the system, the types of the service flows can be automatically detected after the initial model is set, and compared with the prior art, QoS parameters do not need to be manually input, so that the use convenience is greatly improved, and the practicability is higher. According to the system, after the service flows are classified, a more appropriate scheduling algorithm can be selected according to the service types, the overall resource utilization rate and QoS satisfaction rate of the system are improved, and the overall performance effect of the system is improved.

Description

technical field [0001] The present invention relates to a network system, more specifically it relates to an adaptive software-defined space-ground integrated network system. Background technique [0002] The space-ground integrated network is based on the ground network and extended by the space network, covering natural spaces such as space, air, land, and ocean, and providing information security infrastructure for various user activities such as space-based, sea-based, and land-based. . Its ground segment includes traditional ground users, routers, and ground stations, and its space segment includes low-orbit satellites (LEO), medium-orbit satellites (MEO), and high-orbit satellites (GEO). The space-ground integrated network is a network system that uses Internet technology to realize the interconnection and intercommunication of the Internet, mobile communication network, and space network, connects the three types of network service carrying methods, and uses a common...
