The development of new Quality of Service (QoS) control strategies is essential for improving the global quality of the services provided by application servers operating in business-to-business (B2B) scenarios. Although the development and validation of new QoS control strategies based on prototypes is costly and time-consuming, simulation techniques can noticeably reduce the development effort. A simulation model of the application server and its clients is required. Later, any QoS control strategy can be integrated into the model between the clients and the server. The available models are too simplistic to represent the complex applications currently executed in application servers. This article introduces a new model, which is capable of representing the current applications with a high degree of accuracy. As an application representative of the modern B2B environments, the TPC-App (Transaction Processing Performance Council) benchmark has been modeled.
