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.
