Asynchronous Timed Web Service-Aware Choreography Analysis

Abstract

Web services are the main pillar of the Service Oriented Computing (SOC) paradigm which enables applications integration within and across business organizations. One of the important features of the Web services is the choreography aspect which allows to capture collaborative processes involving multiple services. In this context, one of the important investigations is the choreography compatibility analysis. We mean by the choreography compatibility the capability of a set of Web services of actually interacting by exchanging messages in a proper manner. Whether a set of services are compatible depends not only on their sequences of messages but also on quantitative properties such as timed properties. In this paper, we investigate an approach that deals with checking the timed compatibility of a choreography in which the Web services support asynchronous timed communications.

Towards Timed Requirement Verification for Service Choreographies

“…Our approach extends previous works based on timed automata [18], [17] that are concerned with the compatibility analysis of timed services. In this work, verification is restricted to checking the absence of deadlock in a composition of services.…”

Incremental service level agreements violation handling with time impact analysis

“…In [15], the authors modelled the time properties together with the workflow model and use it to checks the conformance of timed orchestration against the global timed choreograph in the collaborative processes. In [18], they modelled timed properties based on the timed automata and use it for analyzing time compatibility of asynchronous services. The work by [46] modelled the timed properties based on Hierarchical Colored Petri Net and use it for analyzing time consistency in business collaboration.…”

Reo + mCRL2 : A framework for model-checking dataflow in service compositions

“…This is suitable for the verification of service compositions already implemented, but does not support the modeling of choreographies that require data and time-aware coordination. Models and frameworks were developed to check service/process compatibility, including data-aware and time-aware business protocol compatibility in [34,28,27]. Our work generalizes these approaches by providing a graphical language that allows designers to build connectors and, thus, create valid service compositions from services that may not be directly compatible.…”
