谈谈污水泵的实用节能改造技术

随着网络上web服务数量的剧增,面对用户提交的一个服务请求,可能同时存在多个功能上与之相匹配的服务,而这些服务非功能性因素(如服务响应时间、可靠性等)可能存在很大的差异,因此,服务匹配的任务不仅仅是为用户找到一个可用的服务,而且应该对多个功能相似的服务加以区别,为用户找到一个性能最好的服务。为此本文改进了传统的web服务架构,引入了服务质量QOS作为衡量web服务非功能性因素的标准,建立了可扩展的QOS模型,提出基于此模型的QOS计算方法,通过对相似服务的QOS进行计算,能筛选出性能最好的服务返回给用户。

Research on Web Service Matching Based on The QOS computation

As the amount of the web service on the internet is sharply increasing,there may be several services which can meet the user's request functionally when a user presents a service request .However,the non-functional properties of these services,such as the response time, cost and so on,may be greatly different.So the mission of service matching is no longer to find a service that can be used by customer normally but to differentiate them and pick up a service with the best performance.Therefor we improved the traditional web service model and took the quality of service(QOS) as the standard with which the non-functional properties can be measured objectly.Besides,we established a QOS model and put forward the method of QOS computation based on this model.By evaluating the QOS of the service with similar functions,we can find the best service for users.
