基于分布式文件系统的即插即用方法研究

Research of Quick Insertion and Usage Method Based on Distributed File System

按照地球剖分理论,地球表面经过剖分后,单个剖分面片将对应所属的地理信息数据载体。在实际应用中需要动态调度不同面片的数据,与之对应的存储载体频繁接入、退出系统。分布式文件系统是目前海量数据存储的首要解决方案,但尚未广泛应用到全球地理信息系统中。以分布式文件系统理论为基础,通过物理、协议、应用三个层次的分析,提出包括网络环境即插即用、网络资源搜索技术以及全球多维GIS数据模型设计等在内的关键技术,以实现全球地理信息系统中存储设备灵活接入和移出存储集群,为全球地理信息系统的存储资源管理提供积极的思路与方法。

By the theory of global partition, every partition slice can contact with its geographical information data storage after the globe is partitioned. In the occasion of practical usage,dynamic data movements of different partition slice are usually needed, the devices which store information get in and out of system frequently. Distibuted file system is now the main resolvement for massive data storage,but hardly applied in global GIS. Based on distributed file system brings forward corresponding key techniques and methods including network quick insertion and usage, network searching techniques and global multi - dimentional data module designing,for the fulfillment of agile getting in and getting out with the storage devive. This paper supplies positive idea and method for management of global GIS.
