Haverkort Rheinisch-Westf sche Technische Hochschule Aachen,? Germany Computer communication systems and distributed systems are now capable of providing various service improvements. In this book, the author describes the techniques and methods used to evaluate the performance of computer communication systems, thus covering all aspects of performance-based model evaluation. Notable features in this book include: * Coverage of all major techniques of performance evaluation * Non-mathematical approach to problem solving, explain and illustrate the performance evaluation techniques * Assessment techniques for stochastic processes, single server queues, queuing networks and stochastic Petri nets * Applications numerous studies, including token ring systems, client-server systems, and wide-area network * Substantial number of practical exercises and examples. For a computer or electrical engineers who design and implement computer communication systems, this book provides an excellent overview of methods and techniques used to construct and solve performance models.
