摘要
服务注册中心(UDDI)是SOA的重要组成部分,为解决UDDI存在的单点故障和扩展性等问题,人们提出了附属服务注册中心和P2P等解决方法,但实际效果较差。现采用"在密集区域投放服务点"的思路,提出一种具有超级节点的语义路由UDDI模型SPSR-UDDI,模型依据点强度优先连接原则,动态调整节点间的部分连接关系,使得全局服务响应时间较短;通过建立网络演化模型,实现了网络自组织演化过程,仿真实验验证了其有效性。
Web server registration（UDDI） is an important part of the SOA. To solve the Single Point of Failure and its expansibility in UDDI, the researches proposed some solutions such as the Affiliate Registry and Peer-to-Peer, but their effectsdo not meet the need. By selecting a server-node at dense network area,the papar proposed a new model SPSR- UDDI （Super Peer and Semantic Routing UDDI）. The connection between nodes will be dynamically adjusted by the principle of vertex weight priority,which makes that whole time of server response be the shortest. The paper built a model of network evolvement to achieve network＇s self-organized evolvement process. The paper gave our experiment results that validate the validity of new strategy.
