Abstract :
Along with the rapid growth of the Web service, the research of non-functional properties of Web service(QoS) becomes a hotspot. The work in this paper is based on an extended service model. It puts forward a metric policy of comprehensive QoS, and the matching algorithm including two aspects: non-QoS constraint and QoS constraint. The experimental results prove that the algorithm is reliable and sensitive to constraint conditions.
