摘　　要：副本技术是网格中提高数据访问和处理效率的关键技术。在深入研究现有副本技术的基础上,结合副本动态管理策略和网格体系结构的特点,利用Globus提供的副本服务相关组件,设计了副本动态管理方案,并以副本管理中最重要的副本创建模块为例,阐述了系统的实现过程。该方案能够对网格环境下副本进行有效的动态管理。Replica technology is the key grid technique to improve the efficiency of data access and processing. In this paper, with the combination of the replica dynamic management and the grid infrastructure features, a replica man- agement method is designed by using Globus＇ replica service components based on the research of current replica tech- nology. The most important creating model is taken as the example to deliberate the implementation of the replica management system. The system can manage replicas dynamically in the Globus grid environment.
