Under the background of the rapid development of ground mobile communication,the advantages of high coverage,survivability,and flexibility of satellite communication provide air support to the construction of space information *** to the requirements of the future space information communication,a software-defined Space-Air-Ground Integrated network architecture was *** consisted of layered structure satellite backbone network,deep space communication network,the stratosphere communication network and the ground *** Space-Air-Ground Integrated network was supported by the satellite backbone *** provided data relay for the missions such as deep space exploration and controlled the deep-space spacecraft when *** addition,it safeguarded the anti-destructibility of stratospheric communication and assisted the stratosphere to supplement ground network *** this paper,algorithm requirements of the congestion control and routing of satellite backbone protocols for heterogeneous users’services were *** algorithm requirements of distinguishing different service objects for the deep space communication and stratospheric communication network protocols were *** the realistic demand for the dynamic coverage of the satellite backbone network and node cost,the multi-layer satellite backbone network architecture was *** this basis,the proposed Software-defined Space-Air-Ground Integrated network architecture could be built as a large,scalable and efficient communication network that could be integrated into space,air,and ground.
