An analytic multiservice performance model for a digital link witha wide class of bandwidth reservation strategies

The author presents a study of a digital link that carries two traffic streams, each with its own bandwidth and service time requirements. The streams are modeled as two-state Markov-modulated Poisson processes. Thus, in addition to Poisson streams, one can study peaked streams or streams requiring a more complex specification. The author defines a flexible class of controls called extended bandwidth reservation (EXBR) that may be used to achieve a variety of objectives. EXBR includes as special cases most of the control strategies studied in the literature and thus provides a single platform to study different service integration alternatives. The model will predict the blocking performance of each service and the channel throughput. Numerical results illustrating the model are presented
