Developing aggregate traffic intensity model for performance evaluation of global satellite systems

This paper is concerned with the development of an aggregate traffic intensity model suitable for the performance evaluation of the intersatellite link (ISL) network in global satellite systems, particularly applicable to support the dimensioning of satellite networks and for computer simulations of various procedures in the ISL network segment. The model consists of four modules considering global distribution of traffic sources and destinations, temporal variations of traffic source intensity, traffic flow patterns between regions, and statistical behavior of aggregated traffic sources. To support universal utilization of the proposed aggregate traffic intensity model, the individual modules need to be efficiently integrated and implemented as a highly parameterized software tool.
