HTCPNs–Based Modelling and Evaluation of Dynamic Computer Cluster Reconfiguration

Abstract

Abstract. An extension of HTCPNs-based software tool for Internet systems modelling and evaluation has been proposed in the paper. After the extension the tool provides new possibilities for modelling and analysis of dynamic cluster reconfiguration algorithm. Some implementation details of the algorithm has been presented. The algorithm has been preliminary assessed by simulation.

Response Time Analysis of Distributed Web Systems Using QPNs

“…Sometimes elements of the control theory are used to manage the movement of packages in web servers [1]. Experiments connected with simulation models are the second way especially when there are many nodes [1,8,9]. Applying experiments and models greatly influences the validity of the systems being developed.…”

Performance Analysis of Distributed Internet System Models using QPN Simulation

“…To describe Internet systems such formal methods like Queuing Nets and Petri Nets are used. Sometimes elements of the control theory are used to manage the movement of packages on web servers [6]. Experiments are the second way [7].…”
