Resumen de Comments on: Queueing models for the analysis of communication systems 2
Alexander Dudin
In the article, authors restrict their attention to the class of discrete-time single-server queueing models useful for performance analysis of communication systems. This is quite natural because the leader of the author’s group professor Herwig Bruneel has the great experience in analysis of discrete-time queues, see his book Bruneel and Kim (1993) published twenty years ago and an impressive amount of journal and conference papers published by the authors after this book. As the authors mention, queueing models in discrete-time are very appropriate to describe traffic and congestion phenomena in digital communication systems, since these models reflect in a natural way the synchronous nature of modern transmission systems, whereby time is segmented into intervals (“slots”) of fixed length and information packets are transmitted at slot boundaries only, i.e., at a discrete sequence of time points.
