基于代理的异构空间数据网格互操作研究

Seamless Integration of Spatial Information Grid with Heterogeneous Data Grid Using Broker-based Model

在分析空间信息网格SIG(spatial information grid)可扩展性的基础上,描述了基于SRB(storage resource broker)的SIG异构数据网格互操作接口设计和信息通讯流程,并以TeraGrid的PTO(purdue terrestrial observatory)数据网格互联为例,对实验结果进行了分析。

This paper discusses the special problems of spatial information integration and some features of broker-based data management model.We demonstrate the prototype of building broker-based model to integrate heterogeneous data grids,and managing transparent access to the related sources.The paper also describes our experiences of case study on seamless integration with Purdue tera grid data by using storage resource broker,which is based on the extensible data service interfaces of China spatial information grid.
