| It is a direct factor that how long the file transmission uses judges the efficiency of transport mechanisms. In this paper, we introduce a new transmission method to advance the transmission efficiency of the large data files. The purpose is to relieve the phenomenon when the files are transferred, the congestion happened or because of the low utilization of bandwidth, the files can not be transferred. In this paper we study the use of parallel-path to transfer large data files, as well as the feasibility of dynamic management copy during transmission if the network conditions encountered an unknown file which leads to the files can not be transferred. The advantage of this transmission method is to speed up the file transferring rate, reduce the file transferring time and to enhance the stability of transmission. Not only the simulation result of the transmission model is completed, but also the result of simulation program is achieved concretely. In this article, we analyze the difference between the traditional single copy data transmission and the multiple copy data transmission, and finally, by the simulation and realization program, three transmission methods were compared. The experiments showed that the model of adaptive dynamic path file transmission based on gridding circumstance had good transmission performance. |
