A dynamically modified load balancing routing strategy, named Dynamic Modified routing table based on Load Balance (DMLB) was proposed in this manuscript for the problem of congestion and packet loss, which was caused by uneven distribution of business traffic in the low earth orbit (LEO) satellite network. Different from the traditional routing protocol for the satellite, the strategy forms a kind of fast forwarding through the steps of geographical location-based traffic prediction, calculation of the entire network routing forwarding table based on weighted shortest path and dynamic correction of load balancing based on priority. These lead to an efficiently updated routing protocol. Simulation results show that the proposed DMLB strategy has better load balancing capabilities and smaller rerouting convergence time, ensuring the reliability of delay-sensitive service transmission, reducing link management overheads, and saving on-board computing resources.
