应用于网格文件传输的全局动态调度算法

An global dynamic scheduling algorithm using gridFTP

给出了一个应用于高带宽的网格文件传输的全局动态调度算法,该算法基于文件传输路径优化与并行机制,并吸收了网格文件传输"多跳路径散列传输"和"多重路径传输",兼有二者的优点。试验结果表明,该全局动态调度算法对网格文件传输的性能(如吞吐量和反应时间)有重大改进。

Based on the file transfer Path optimization and the available network parallelism,this paper presents a file transfer global dynamic scheduling algorithm that incorporates the two optimizations of multi-hop path splitting and multi-pathing.This algorithm makes use of information from past GridFTP transfers to estimate network bandwidths and resource availability.The experimental results show that this algorithm achieve significant performance improvement.
