传统Web服务发布与发现机制中,服务提供者和消费者仅以Web服务的功能性属性作为其发布和发现服务的依据,并没有考虑诸如价格、执行时间、可靠性等的非功能性属性,即QoS(Quality of Service)。提出一个基于QoS的Web服务发布和发现框架。该框架在传统Web服务三脚架构中引入QoS broker,以实现QoS信息的收集、测试、监控和管理;全面地从Web服务提供者、服务使用者和UDDI三个角度探讨支持QoS的服务发现和发布;实现QoS信息的动态收集、评估和管理,以确保Web服务发布和发现过程能够基于动态更新的QoS信息,使服务选择过程更加有效。
In the traditional Web service publishing and discovery mechanism, service providers and consumers regard only the functional attributes of Web services as the basis for their publishing and discovery services, without considering non-functional attributes such as price, execution time, reliability, That is, QoS (Quality of Service). Proposed a QoS-based Web service publishing and discovery framework. This framework introduces QoS broker into the traditional Web services tripod architecture to collect, test, monitor and manage QoS information. It also discusses the QoS discovery and release from three perspectives: Web service provider, service consumer and UDDI ; Achieve the dynamic collection, evaluation and management of QoS information to ensure that the Web service publishing and discovery process can make the service selection process more efficient based on the dynamically updated QoS information.
