<p>A client-server system is a distributed system where a server station receives requestsfrom its client stations, processes the requests and returns replies to the requestingstations. The authors consider client-server systems in which a set of workstationsaccess a file server over a local area network. The systems are modelled by a class ofstochastic Petri nets. The mean response time, the throughput and the parametricsensitivities are evaluated for a client-server system based on token ring network and asystem based on CSMA/CD network. These models are different from the prevalentperformance models of token ring or CSMA/CD network systems because of the messageinterdependencies introduced by the clients-server structure. An approximateanalytic-numeric method rather than simulation is used to solve the models. The solutionmethod and the accuracy of approximation are also discussed.</p>
