Reo is an exogenous coordination language for compositional construction of the coordinating subsystems of component-based softwares. Constraint automaton has been proposed as the operational semantics of Reo networks. The main goal of this work is to prepare a model checking based verification environment for component-based systems, whose component connectors are modeled by Reo networks and Constraint Automata. We use the methods of compositional reduction and abstraction in model checking of component-based systems and their component connectors modeled by Reo.
