A Framework to Support QoS-Aware Usage of Web Services

Web services offer an easier, effective, efficient way to support a service paradigm. However, there is lack of adequate QoS support in using web services. In this paper, we propose a framework to support QoS aspects of web services. Three new elements are added to the original web service framework: QoS Server, QoS UDDI Broker and QoS Agent. In this framework, a requester is able to query more flexibly by using history QoS data of each web service with few load.
