基于多副本的动态自适应数据传输模型的研究

Research of dynamic and self-adaptive transfer model based on multiple replicas

提出了基于多副本的动态自适应数据传输模型,并详细介绍了该模型所采用的动态任务分配算法,对比分析了与传统的基于单一副本数据传输方法的区别,最后运用GridFTP对两种方法作了详细的验证和比较。实验结果表明基于多副本的动态自适应数据传输模型具有较好的传输性能。

A dynamic and self-adaptive transfer model based on multiple replicas is proposed and its dynamic allocation algorithm is introduced in details. To analyze differences between traditional single replica transfer method and this proposed method, comparison and analysis are made. At last, GridFTP is used to test the performance of this model, and the result proved that dynamic and self-adaptive transfer model based on multiple replicas had a better performance.
