| Abstract: | 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. |
