Traffic class dependent routing in packet-switched non-geostationary ISL networks

This paper addresses traffic class dependent routing in the intersatellite link network of a non-geostationary packet-switched satellite system. Three different traffic classes are considered, each with its particular optimisation criteria. Performance analysis, in terms of average packet delay of particular traffic class and average packet throughput, has been evaluated using specifically developed simulation software to model the ISL network. Four different simulation scenarios were used to investigate the impact of different scheduling and routing policies on the network performances for different network traffic loads.
