Modeling and behavior checking of component based architecture

In this paper, we study component-based software architectures and report the following results. 1) By defining port operations, we may use port activities to describe process migration. The proposed formalism(port algebra) can be used to describe running time system architecture. 2) In processing checking, the formalism can keep architecture structure unchanged while progresses migrate, which enables us to study runtime system behaviors that are not easy to be checked by model checking tools.
