The global development of communication technology and military applications, the growing demand for satellite communications is driving toward the star on the calculation , the direction of the exchange capacity satellite network development . The satellite constellation by ISLs networking , you can reduce the dependence on the ground gateway , to achieve the rapid transmission of information . Space-based information network , satellite network based on a combination of spatial information resources , so that the interconnection of different track multiple types of satellite systems , and constitutes an organic intelligent system . Integrated information network of space-based reconnaissance and surveillance, environmental and disaster monitoring , navigation and positioning , communications and broadcasting , space defense and confrontation , has a special function and role of the urgent need to develop a major strategic project . The satellite constellation ISLs networking there are still a number of key issues to be studied in depth . This paper focuses on the architecture of the space-based information network , satellite network QoS routing and satellite switching reroute . A LEO / MEO double- Walker constellation of space-based information network architecture based model for the characteristics of China 's geographical position and future communications needs , and that this constellation coverage performance and inter-satellite link simulation parameters kinds of constellation structure to meet the requirements of our coverage , and scalability . The double Walker class constellation of characteristics and flow distribution characteristics of a certain traffic balancing capabilities hybrid routing algorithm of structured THRA ( Taffic - adaptive Hybrid Routing Algorithm) . The simulation results show that the algorithm can better meet the needs of service QoS , and optimize the overall utilization of network resources to some extent . A can take full advantage of the double constellation of structural features and multiple the coverage performance characteristics , based the the candidate satellite set switching rerouting strategy RSCSS ( Re - routingStrategy Based on Candidate Satellites Sets ) for the two types of switching problems in a multi-layered satellite network . Preliminary simulation results show that the effective switching strategy .
