【 摘 要 】

Composite Web service architectures are demanding much guarantee on the Quality of Service (QoS) in order to meet user requirements. Performance evaluation of these architectures has become therefore a very challenging issue, as the task is very complex due to synchronization inside the orchestration of services. We propose in this paper to use stochastic automata networks which a is powerful formalism as it provides semantics to specify synchronization within a very smart formalism. Contrary to previous approaches, the modeling and the performance evaluation of a variable number of remote service invocation become possible. The reported simulation results advocate the use of our approach in the performance evaluation of composite Web service architectures.
