Performance evaluation of distributed system is always a complex task where the service behavior results from a collaboration of partial components behavior those are physically distributed. The authors present an approach to delineate a performance modeling framework in model based service engineering context that proposes a transformation process from high level UML notation to SPN model and solves the model for relevant performance metrics. To demonstrate model based service engineering approach they outline a specification style that focuses on UML collaboration and activity as reusable specification building blocks.
