A Study of BPEL-Based Framework for Optimal Composition of Dynamic WEB Services

摘要：

Based on BPEL,Web services can be composed into complex business process. However, BEPL does neither support to modify Web services during the execution of business process nor provide the mechanism of optimal service. In order to solve these problems, this paper gives a dynamic Web services optimal composition framework grounded on the BPEL and QoS. By using the dynamic binding function of QoS components and the dynamic UDDI discovery of Web service, the business process run-time dynamic selection of Web service will be realized. Web service optimal composition is implemented by Froyd’s shortest path algorithm. So the efficiency in execution of business process will be improved as well.
