摘要
分析了集中式UDDI注册中心存在的缺点。结合P2P技术,基于分布式哈希表提供的高效的数据定位功能,提出了一种分布式Web服务目录系统,讨论了该系统下Web服务的发布与发现过程以及目录系统的维护。在该服务目录系统中,服务的描述信息分布在各个节点上,能够克服集中式UDDI注册中心的缺陷。
This paper analyzes limitations of typical UDDI registry. Utilizing peer-to-peer technology, it proposes a novel distributed Web services catalog service based on the efficient data location ability of distributed hash table. The paper discusses the procedure of Web service publication and discovery under this system, as well as the system evolution. This system enables distribution of description information to each peer, which will overcome the shortcomings of centralized UDDI registry.
