基于Globus平台下的GridFTP客户端的实现

Research and Practice on GridFTP Transmission Mechanism

研究了GridFTP的协议功能及特点,详细分析了第3方传输、并行传输和条状传输的传输机制及性能。并阐述了在GT4环境下部署GridFTP服务方法,利用GridFTP客户端API开发包,创建一个GridFTP客户端应用程序,实现以上3种传输方式。

Data transmission was an essential problem in the grid.Data were not effectively attained in the grid without a high speed and effective method.GridFTP is developed to meet the basic needs of the data transmission in the grid by extending the protocol of FTP.This study discusses several transmission modes and importance of parallel transmission.The experiment indicates that transmission efficiency is related to the parallelism,however,the transmission efficiency is not improved infinitely when the parallelism increases.The parallel transmission can obtain optimizing efficiency when it is set on a suitable parallelism.
