摘要
为减少Web服务注册中心的用户响应时间,根据UDDIV3规范在分布式环境下建立跨域服务注册中心系统。将系统分为域间和域内两层,域间使用基于订阅的方式进行数据异步复制,域内使用动态主从复制方式进行数据同步复制,并优化UDDI的数据结构。分析优化前后的数据量,对该系统和节点间完全复制的系统进行比较。实验结果表明,该系统能够有效地提高服务注册中心的性能。
In order to reduce the user response time of Web service registry center, on the basis of the characteristics of Universal Description Discovery and Integration(UDDI) standard, this paper divides the system into two layer of inter-domain and internal-domain, and establishes cross-domain system. In this system, inter-domain uses subscription-based approach for asynchronous data replication, internal-domain uses dynamic master-slave replication for synchronization data replication. It optimizes the UDDI data structure. The amount of data before and after optimization is analyzed. The system and complete duplicate systems between nodes are compared. Experimental results show that the system can effectively improve the performance of the service registration center.
