摘要
利用GT4提供的网格服务功能研究了基于网格服务的GridFTP数据传输的性能,分别在关闭网格服务环境下和开启网格服务环境下,观察利用GridFTP进行不同文件类型和大小的数据传输情况,分析了网格服务对GridFTP数据传输的影响,并针对目前GridFTP进行跨异构平台传输过程中存在的问题,提出了几种改进方法。实验结果表明,将网格服务应用于Grid-FTP数据传输,可以改善其传输性能,提高其传输质量。
The data transmission performance of GridFTP based on grid service are researched with the grid services functions provided by GT4, respectively in the open grid services environment and without it, observes the data transfer cases of different file types and sizes by GridFTP, analyzes the impact to GridFTP data transfer by the grid services, and presentes several improvement methods, against existing problems when GridFTP across heterogeneous platforms. It can improve the transmission performance of GridFTP and improve its transmission quality by using grid services.
