An explicit method for adjusting the sending window using the number of TCP flows at the destination satellite and the number of satellites in the path is proposed. With this method, different reactions to packet-droppings are executed for different-delay flows. The simulation results using NS2 show that the performances and fairness of different-delay TCP flows are enhanced distinctly, the packet-droppings are decreased, and the bandwidth utilization of the downlinks of the destination satellite is increased effectively while dealing with channel drops.
Key words： LEO satellite networks; TCP; fairness; bandwidth utilization; channel drops
