Abstract

In this paper we propose a model of load traffic with variable intensity for a switch node. Our model is based on a family of periodic input patterns (PI-patterns) for uniform traffic. We have used the family of patterns in order to study the throughput of a crossbar switch node. Our simulation studies use the Generalized Nets (GN) model of the known PIM-algorithm. The simulation results of a GN-model using the family of PI-Patterns are presented and analyzed. It is shown that our family of patterns for variable traffic intensity enables us to estimate the maximal throughput of the switch in case of uniform traffic.
