HTCPNs-Based Tool for Web-Server Clusters Development

摘要

A new software tool for web-server clusters development is presented. The tool consist of a set of predefined Hierarchical Timed Coloured Petri Net (HTCPN) structures - patterns. The patterns make it possible to naturally construct typical and experimental server-cluster structures. The preliminary patterns are executable queueing systems. A simulation based methodology of web-server model analysis and validation has been proposed. The paper focuses on presenting the construction of the software tool and the guidelines for applying it in cluster-based web-server development.
