基于Web Services的分布式服务发现系统的研究

Research on Distributed Service Discovery System Based on Web Services

Internet中分布着大量不同类型的计算服务,为了更有效的查找这些服务,设计了一个面向计算的分布式服务发现系统。网络中的计算资源被部署为Web服务,并通过组件之间的互操作性调用服务。改进了UDDI中的服务订阅机制,并给出了服务部署、服务发布、服务定位和授权认证等关键问题的解决方案。利用集群及PC机环境构建系统,并进行了实际测试。

A great lot of different computing services are distributed in Internet. For searching these services effectively, a distributed service discovery system for high performance computing is designed. Computing resources are deployed on Web Services. System transfers services by interoperations between components. The service subscription mechanism in UDDI is improved. Some key problems such as services deployment, services publication, service location and authorization are elaborated. The system is implemented by cluster and some PCs in our laboratory.
