摘要： 基于对服务发现需求的分析,将服务匹配过程划分为类型匹配和实例匹配两个阶段,提出了基于两阶段匹配的网格服务发现模型。该模型以VO为管理单位,在VO内采用两层发布架构。初步的实验结果显示该模型能有效地聚集服务信息并避免大量动态更新带来的负载。

Abstract: Based on the analysis for the requirements of service discovery,this paper divides the service matching process into 2 stages: service type matching and instance matching and a grid service discovery model based on 2-Stage matching is proposed to enable more effective service discovery.In the model,VO is utilized as the managerial unit for grid services and a two-level publication architecture is adopted.The initial simulation results show that the model can effectively aggregate the service information and avoid the workload caused by frequent dynamic updating.
