Abstract:

File transfer strategies on the Internet directly affect the efficiency of resource utilization and file transfer, and this is more obvious in cloud computing environments where there are all kinds of resources, especially when transferring a large number of small files. Aiming at this problem, we present a transfer strategy for small files based on packing strategy, and an optimization mechanism for file packets as well. We pack small files before they are transferred and stored. Packaged files are unzipped and then stored at the serverend. The transfer process of IO operations is therefore greatly reduced and the efficiency of file transfer is also enhanced. Experimental results verify the correctness of the proposed strategy, which greatly improves the efficiency of small file transfer in cloud environments and resource utilization .
