A Scenario-based Framework for Perceiving Crossbreed Service Interactions

The service-oriented computing provides technologies allowing multiple enterprises to integrate their businesses over the Internet. Typical execution behavior in this type of converged schemes comprises a network of autonomous peers interacting with each other. Modeling and analyzing the interactions among different services is a crucial problem in this domain. It is a particularly challenging task since no single party has access to the internal states of all the participants. Desired behaviors have to be specified as constraints on the interactions among different peers since the interactions are the only observable global behavior. Besides, it might be meaningful to specify the interactions among different parties before the services are implemented. Undeniably, one of the main requirements is preserving the autonomy of each participating partner during the interaction, without restricting the overall goals of the common process. Thus, mechanisms orchestrating distributed service workflows are needed. The scenario-based framework for perceiving crossbreed service interactions examined in this paper efforts to meet these requirements. © 2011 Published by Elsevier Ltd.
