Abstract:
This paper brings forward a QoS evaluation model of Web service by adding a QoS authority part on the existing UDDI criterion. It defines a set of QoS categorization tModels, and introduces the concept of QoS quantification. It uses a monitor mechanism initiatively and a feedback mechanism from service consumers for evaluating and adjusting QoS value of Web service dynamically in UDDI. The impartiality, trustworthiness, and real-time characteristics of QoS information are ensured.

摘要: 在现有UDDI规范中增设QoS认证组件,提出一个Web服务QoS评估模型。定义一组描述Web服务QoS属性分类的tModel,在引入QoS量化概念的基础上,结合QoS认证中心主动监视和服务消费者QoS反馈机制,对UDDI中注册的Web服务QoS进行动态评估和调整,保证了Web服务QoS信息的公平性、可信性和实时性。
