摘　　要：云存储技术通过集群应用、虚拟化、分布式文件系统等将网络中大量不同类型的存储设备集合起来协同工作,以此缓解老式数据中心的存储压力。目前许多涉农信息平台的文件管理与共享浪费了极大的空间,越来越多涉农企业的发展需要一个基于云存储技术的农村综合信息服务平台。以云存储为设计基础,一方面通过研究重复数据删除技术,提出了一种在客户端利用Hash的MD5算法进行文件级别的重复数据删除操作后再将数据存入云服务器中的方法,以此为涉农信息平台提供企业内部统一的文件共享;另一方面利用实时性更强,占用网络带宽更少,以及通信效率更高的Web通信协议,完整地采用基于HTML5 Web Socket协议的Web通信来实现涉农企业间的网络商务洽谈。Cloud storage technology, through clustering applications, virtualization, distributed file systems and other functions, let a large variety of different types of network storage devices set up cooperative work, in order to alleviate the pressure of old data center storage. Many of document management and sharing of the current agricultural information platforms waste a great space, with the development of information technology, more and more agricultural enterprises need a comprehensive rural information service platform based on cloud storage technology. This paper takes cloud storage as the design foundation, on the one hand through the research data deduplieation technology, puts forward a kind of repeated data file level in the client using MD5 Hash algorithm for the delete operation after the data will be stored in the cloud server method, so as to provide agricultural information platform and the internal unity of the file sharing; On the other hand, the paper uses Web communication protocol, with real-time, occuping less network bandwidth, and communication more efficient, completely aelopts HTML5 Web Socket based on Web communication protocol to realize agriculture inter enterprise network business.
