Abstract :
In recent years, Web services are getting popular. In order to have more reliable services on the Internet, QoS (quality of service) plays an important role. We extend the WSDL with an optional attribute in order to control the level of QoS. The extension enables Web services providers to support partial request satisfaction by a priority attribute controlling the priorities of WSDL requests and the corresponding sub-requests. We have performed a set of experiments to demonstrate the significance of the partial request satisfaction by with a range of values of the priority attribute. The results are interesting and demonstrated the usefulness of the new parameter.
