In this paper, the structure of the complex web service composition relationship and the insufficiency of the conventional web service deployment was discussed, then it introduced a method to describe the complex composition relationships between web services. This material also serves as a guide for readers to build an elastic complex web service deploy platform which can archive real time monitoring...
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...
With the development of SOA (service-oriented architecture) and SOC (service-oriented computing), the quality of service (QoS) was more and more important than before. How to access, store and measure the QoS in complex network has been a key work for the SOA. An expanded service model supporting QoS is proposed in this paper, and the model supports service publishing, selection based on QoS. In the...
