【摘要】 目前比较流行的Web服务注册管理模型UDDI存在实际使用情况较差的问题.主要原因在于:集中式的管理导致其随着服务数量的增加变得较难管理和维护;另一方面,目前UDDI只能提供基于关键字的目录查找,造成了服务查找有效性较差的问题.文中提出了一种改进的分布式服务注册管理模型(pUDDI),利用分布式结构和Web服务池机制减轻Web服务注册中心的负担和提高注册库中服务查找的有效性.更多还原

【Abstract】 Nowadays there exist some tough problems in the way of present UDDI registry and repository. For example, centralized configuration becomes impractical for a large number of web services. Furthermore, present UDDI registry only provides a keyword-based query mechanism which leads to a low efficiency of querying. In this paper, an improved distributed architecture named as pUDDI is proposed for these problems. With the distributed architecture, the web service is published within one or more pUDDIs so as to avoid the performance bottlenecks in centralized configuration. With web service pool mechanism, efficiency of finding the web service is greatly enhanced.更多还原
