Agent based dynamic execution of BPEL documents

Abstract

Web Services are the most promising innovative solution in order to remove business and technical obstacles for e-business. They support a true service oriented architecture that is designed to securely expose business logic beyond the firewall. As the momentum around Web Services increases, there is a growing need for effective mechanisms to coordinate the interaction among them. Business Process Execution Language for Web Services (BPEL) is a good candidate, such that it satisfies the needs of the business to enable this interaction. However, BPEL still is far from fulfilling all the requirements of composition. In this research, we constructed an architecture to improve performance of parallel executions in BPEL documents. Our architecture, by the help of our controller agent, allows dynamic execution of statically designed flow with respect to customer defined issues and QoS parameters at both implementation time and runtime. © Springer-Verlag Berlin Heidelberg 2005.
