The uneven distribution of network demand over time and space causes the congestion and the data damage due to high error rates,a multi-path and multi-service routing strategy for LEO/GEO satellite networks is explored.In the strategy,the space-time factor is introduced into the link cost formula,and the transmission path is selected by considering the link state,multi-path flag,the sensitivity of the traffic to the delay and the user level.The simulation results show that the routing strategy has better pe...
