Reo is an exogenous coordination language for component connectors extending data flow networks with synchronization and context-dependent behavior. We propose an operational model of Reo based on Buchi automata in which port synchronization is modeled by records labeling the transitions, whereas context dependencies are stored in the states. We provide a composition operator which models the joining...
Constraint automata as acceptors of timed data streams are the semantic models of component connectors specified in the language of Reo. In this paper, we investigate the augmentation of the theory of constraint automata by live- ness and fairness requirements. We define the notion of liveness for constraint automata as a set of infinite runs and show that our definitions of weak and strong fairness...
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...
