“…It consists of a set of integrated tools for the Eclipse platform. 5 The framework provides functionality for converting high-level modeling languages, such as UML, BPMN and BPEL to Reo [20], for editing and animation of Reo models, generation of automata-based semantical models from Reo, modeling and verification of QoS properties and tight integrations with external model checking tools such as Vereofy [13] or PRISM [45].…”

“…With respect to the verification of Reo connectors, the work most closely to ours is the Vereofy model checker [13]. Vereofy uses two input languages, namely, Reo Scripting Language (RSL), and a guarded command language called Constraint Automata Reactive Module Language (CARML) which are textual versions of Reo and constraint automata, respectively.…”

“…These tools include algorithms to compute constraint automata and coloring tables used to model check and animate the execution of graphical Reo circuits [10]. Moreover, the Vereofy [13] tool developed at the University of Dresden provides model checking facilities for verifying properties of constraint automata.…”

Abstract. The paradigm of service-oriented computing revolutionized the field of software engineering. According to this paradigm, new systems are composed of existing stand-alone services to support complex cross-organizational business processes. Correct communication of these services is not possible without a proper coordination mechanism. The Reo coordination language is a channel-based modeling language that introduces various types of channels and their composition rules. By composing Reo channels, one can specify Reo connectors that realize arbitrary complex behavioral protocols. Several formalisms have been introduced to give semantics to Reo. In their most basic form, they reflect service synchronization and dataflow constraints imposed by connectors. To ensure that the composed system behaves as intended, we need a wide range of automated verification tools to assist service composition designers. In this paper, we present our framework for the verification of Reo using the mCRL2 toolset. We unify our previous work on mapping various semantic models for Reo, namely, constraint automata, timed constraint automata, coloring semantics and the newly developed action constraint automata, to the process algebraic specification language of mCRL2, address the correctness of this mapping, discuss tool support, and present a detailed example that illustrates the use of Reo empowered with mCRL2 for the analysis of dataflow in service-based process models.

“…The behavioural point of view requires a concrete semantic model for the coordination pattern. For illustration purposes, models of Reo-constraint automata (CA) [6,5] and reo automata (RA) [9]-are adopted. The reader is referred to Appendix A, where the definitions of these automata are reproduced.…”

“…In particular, standard notions of similarity and bisimilarity in such models [5,9] can be used to compare the behaviour of the coordination pattern before and after the application of a reconfiguration. Alternatively, they are used to compare the effect of applying different reconfigurations to the same pattern.…”

Software connectors encapsulate interaction patterns between services in complex, distributed service-oriented applications. Such patterns evolve over time, in response to faults, changes in the expected QoS levels, emergent requirements or the reassessment of contextual conditions. This paper builds up on a model for connector reconfiguration to introduce notions of reconfiguration equivalence and refinement allowing for reasoning about them. This paves the way towards a (still missing) calculus of connector reconfigurations.
