Mean value analysis for polling systems
The present paper deals with the problem of calculating mean delays in polling systems with either exhaustive or gated service. We develop a mean value analysis (MVA) to compute these delay figures. The merits of MVA are in its intrinsic simplicity and its intuitively appealing derivation. As a consequence, MVA may be applied, both in an exact and approximate manner, to a large variety of models.
متن کاملHeavy traffic analysis of polling models by mean value analysis
In this paper we present a new approach to derive heavy-traffic asymptotics for polling models. We consider the classical cyclic polling model with exhaustive or gated service at each queue, and with general service-time and switch-over time distributions, and study its behavior when the load tends to one. For this model, we explore the recently proposed mean value analysis (MVA), which takes a...
متن کاملAn Elementary Derivation of Mean Wait Time in Polling Systems
Polling systems are a well-established subject in queueing theory. However, their formal treatments generally rely heavily on relatively sophisticated theoretical tools, such as moment generating functions and Laplace transforms, and solutions often require the solution of large systems of equations. We show that, if you are willing to only have the average waiting of a system time rather than ...
متن کاملMean Value Analysis for Blocking Queueing Networks
Mean value analysis is an exact solution technique for infinite capacity queueing networks and enjoyed widespread popularity during recent years. It considers the behavior of the system by stepwise increasing the number of jobs in the entire network, thus it is well-suited for the analysis of queueing networks with blocking. In this work, an approximation is introduced for the mean value analys...
متن کاملAnalysis and Optimization of Polling Systems
The basic polling system is a system of multiple queues, attended to by a single server in a cyclic order. Polling systems arise naturally in the modelling of many communication, computer and production networks where several users compete for access to a common resource. Such applications also give rise to several variants of the basic polling system, like periodic polling; here the server vis...
