The generalized D[X]/D/1 queue: A flexible computer communications model

View publication

Abstract

A generalization of the D[X]/D/1 queue is investigated, where independent and identically distributed (i.i.d) batches of customers arrive at a single-server queue periodically. The service requirement of a customer is a fixed constant equal for all the customers. In the time between two successive arrivals, the server can accommodate exactly K ≥ 1 customers. The queue size and the waiting time distributions for the infinite buffer queue are derived. Important numerical aspects are addressed and simple approximations for light and heavy traffic for various values of K and Poisson distributed batches are proposed. Finally, the analysis for the finite queue is highlighted and its blocking probability derived. © J.C. Baltzer AG, Science Publishers.

Paper

The Use of Priorities on Token-Ring Networks for Multimedia Traffic To guarantee acceptable QoS for multimedia traffic, resource management is required to insure that sufficient capacity from all shared resources is allocated to the priority traffic. Once a multimedia session is accepted and resources have been allocated, the next task is to insure that the high priority multimedia traffic actually obtains the resources which have been allocated to it.
