Communication networks and computer systems have become extremely complex. The statistical resource sharing induced by the random behaviour of users and the underlying protocols and algorithms may affect quality of service. The book introduces the main results of queueing theory useful for analysing the performance of these systems. These mathematical tools are key to the development of robust dimensioning rules and engineering methods. A number of examples illustrate their practical interest.
