The development of new QoS control strategies is essential to improve the global quality of the services provided by application servers operating in B2B scenarios. But the development and validation of new QoS control strategies based on prototypes is costly and takes a long time. However, the simulation techniques can help to reduce the development effort noticeably. Therefore, a simulation model of the application server and its clients is required. Later, any QoS control strategy can be integrated in the model between the clients and the server. But the available models are too simple to represent properly the present complex applications executed in application servers. This article introduces a new model, which is capable of representing the current applications very well. As an application representative of the modern B2B environments the TPC-App benchmark has been modeled.
