Web服务可靠性的阶段模型
A staged model for Web services reliability
摘要
Abstract
To more comprehensively analyze the failure process of Web services and improve the prediction accuracy of reliability, a staged model for Web services reliability is proposed. Firstly, the failure processes of service publication, service discovery, service composition, service binding and service execution in service-oriented architecture (SOA) are described and reliability models in different stage are built according to different failure processes. Then, the staged reliability models are integrated to predict the reliability of Web services. A case study was designed to model the reliability and the staged model was compared with the traditional model. The experimental results show that our staged model can obtain better reliability prediction accuracy than traditional models. Thus, it is more applicable to Web services.关键词
