基于网格的数据传输模型设计与实现

The Design and Implementation of the Data Transfer Model Based on Grid

本文深入分析了网格体系中的数据传输服务,提出并建立了一个面向网格的文件传输模型,该模型突破了传统的资源共享模式,采用负载平衡和容错算法来提供持续可靠的访问。文中给出了依据此模型设计GridFTP系统的详细过程,并且经测试表明,该系统将原本独立的物理服务器联结起来协同工作,实现了资源分布动态自适应调整,为用户提供高性能、高可用性、高可靠性的FTP服务。

On the basis of analyzing the data management service of grid architecture, this paper has Proposed and established face the grid file transfer model, this model broke through the traditional resources shinning pattern, uses the load to be balanced and the fault-tolerant algorithm provides the reliablly visit, according to the above the model, In the article produced the design of the GridFTP system in details, and after the test which indicated that the originally independent physical server will join the joint operation, and has realized the resources distribution with dynamic auto-adapted adjustment, Besides that users can get the resources more quickly and more reliably.
