为了提高UDDI服务注册中心的服务查询效率和有效性,在UDDI标准规定的数据结构基础上增加了服务相关信息和服务QoS信息2个模块,并对服务的查询和发布接口进行了扩展.服务的QoS信息通过UDDI主动监听服务多种属性的方式动态获得.最后将提出的优化系统与其他几种系统的特点进行了比较,并通过实验说明了该系统的服务查询效率更高.%In order to improve query effieiency and effectiveness of service in UDDI service registry, two modules of service-related information and service QoS information based on the data structure specified in the UDDI standard are increased, and the inquiry and published interface of service are extended. The service QoS information is obtained dynamically through a way of that UDDI monitors a variety of properties of service activity. Comparing features of the proposed optimization system with other systems, the experiment shows that the service query is more efficient in this system.
