Modeling and Analyzing Publish Subscribe Architcture using Petri Nets

Abstract

-Software architecture is the foundation for the development of software systems. Its correctness is important to the quality of the software systems that have been developed based on it. Formally modeling and analyzing software architecture is an effective way to ensure the correctness of software architecture. However, how to effectively verify software architecture and use the results from formal modeling and analysis is important to the application of the approach. In this paper, software architecture is modelled using high level Petri nets, and the model is then checked with a model based testing tool called MISTA, and bounded model checking tool Alloy to ensure the correctness of the model. The approach is designed as a two-phase process consisting of model-based testing and bounded model checking to ensure it is both practical and rigorous for analyzing software architecture. We illustrated the idea and procedure via modeling and analyzing the PublishSubscribe architecture. The result has shown that combining bounded model checking with model based testing is an effective extension to ensure the development quality.
