近十年来,计算机网络迅猛发展,同时网络的使用也逐渐增加,信息的数量、种类和分布都达到了一种“爆炸式”的增长。如何存储、分发、组织和管理、高性能处理、分析和挖掘海量分布数据成为许多应用的首要问题。数据网格技术的发展为解决这个问题提供了一条有效的技术途径。而P2P方式作为一个彻底的分布式计算模型,与集中的服务器方式相比,具有很多优势。
Over the past decade, the rapid development of computer networks, while the use of the network has also gradually increased, the number of information, type and distribution have reached an “explosive ” growth. How to store, distribute, organize and manage, high-performance processing, analysis and mining mass distribution of data has become the number one application of the primary problem. The development of data grid technology provides an effective technical solution to this problem. P2P as a thorough distributed computing model, compared with the centralized server approach, has many advantages.
