Abstract :
The message delivery time on a low Earth orbit (LEG) satellite network is analyzed. The LEO network is assumed to be seamless and virtual cut-through switching is proposed for use. Equations to calculate the message delivery time and the probability of a message being delivered successfully using no more than a time delay bound for LEO networks, varying in size and connectivity, are derived. The message delivery times of different LEO networks, varying in network connectivity, are compared. Numerical examples show that with the probability of successful delivery =0.99 and the probability of cut-through =0.5, an 8×8 LEO network with six crosslinks per node can deliver messages 40% faster than with four crosslinks per node for communicating satellites, separated by D hops, where D is the network diameter
