Abstract：Link disruption and connection have a considerable impact on satellite networks routing issues. A link disruption tolerant routing strategy is proposed for multilayered satellite networks. In this strategy, the route table is calculated by means of the topology predictability of satellite networks in nonuniform slots to resolve the routing problems under link disruption circumstances caused by satellite movements, and a dynamic congestion control mechanism and a flood strategy are suggested to ensure the packets’ correct forwarding during system failure period. The simulation results show that this strategy has higher link utilization and less time-space cost of dynamic route calculation, including delay information collection and route table generation.
