Extended Queuing Networks (EQN) are popular models for performance simulation of computer systems and communication networks. The EQN simulator developed in this work provides a simple and efficient simulation environment, which can be seamlessly integrated by XSLT transformations into modern system-design environments. Novel in this approach, is the consistent exertion of XML for all programmed modules of the simulator and the specification of the EQNs itself. The simulation method developed profits from XML Schema and provides a framework for constructing and solving standard Queuing Networks (QNM) as well as EQNs. The application of the XML Path Language (XPath) warrants a simple, robust and error resistant simulation, that can be interfaced with numerous programming languages with an XML interface. The paper presents the simulation method, the underlying XML model, model validation and the analysis of results. In the contribution, we also provide implementation details and experimental results for the prototype simulator.    «
