AOS space data link protocol performance analysis and simulation

In the packet processing and multiplexing of advanced orbit system, the queuing delay and queue size efficiency directly affect the performance of data system. By analyzing the characteristic of space data service, we build three source models of different service and three queuing models of packet processing based on M/G/l queuing theory. Simulation results validates the queuing model is in accord with the theory analysis. A proposed scheduling algorithm based on queuing cost will be helpful to flight vehicles system design.
