Abstract: A method for routing data is proposed in this paper for satellite constellation network. The method combine the widely used OSPF dynamic routing strategy in ground networks and the traditional beforehand computed satellite constellation static routing strategy. Since the dynamic routing strategies can be more reliable and robust but consume more computing resources and network resources, OSPF routing strategy is compressed to meet the hardware requirements in satellite constellation network. Through automatically switch between static and dynamic routing strategy, the satellite constellation network can obtain more reliabilities.
