Performance analysis of distributed Internet system models using QPN simulation

摘要

The paper presents creating web system models. The aim of the work was to develop models of the distributed Internet system that allow the performance evaluation. From many possible methods we have selected Queueing Petri Nets consisted of two classes of formal models (Queuing Nets and Petri Nets). In the paper web systems are modeled by Queueing Petri Nets tool. The paper includes the selected results of models simulation. Our approach predicts the performance of distributed Internet system.
