| Abstract(in English) | Recently, various contents are provided on the Internet and their size is increasing. It is an important issue how users can retrieve the large contents more quickly. In order to achieve such requirement, some researchers have proposed the parallel access schemes that users access multiple servers simultaneously to fetch different portions of a file from the different servers. However, there remain the following two issues in an existing method. (1) The number of divisions must be determined in advance, and (2) available bandwidth between a client and each server is not taken into consideration. In this paper, we propose an adaptive parallel downloading method that dynamically changes th size of requesting block by calculating the throughput of each server at the time. The number of divisions is also determined dynamically by the proposed method. Experimental evaluation using the Internet shows that the proposed method can download a large file in a shorter time than the existing method. |
