Abstract

Single server polling systems often serve as models for parts of cimmunication systems, e.g., multiplexers or Local Area Networks with a single token passing medium access protocol. Simple polling systems can be tracted analytically while certain service disciplines and many asymmetric systems can only be analyzed via simulations. Simulations also allow to obtain the distributions and quantiles of the waiting times and other characteristic values, whereas most analyses only provide the first and second moments. This paper first describes the simulated polling systems. Then it introduces the principle of measurement of distributions and quantiles ina simulation and concludes with results comparing the waiting time distributions and quantiles in systems with different service strategies and asymmetric load. Furthermore, formulae for the throughput of symmetric systems under overload are derived.
