| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | "Parallel Downloading", which divides a file into many pieces and assigns each piece to one of the servers which store the file, has been proposed and reported to achieve high speed file retrieval from many servers in parallel. The conventional method which adopts TCP as a transport protocol has a problem that its performance deteriorates in the network where packet losses frequently occur at the datalink layer. To address this issue, we have already proposed a parallel downloading method which uses SCTP instead of TCP as a transport protocol and focuses on its multistream feature. We discuss how to realize the effective parallel downloading method using SCTP multistream and evaluate it. Here, we use only one server to simplify the problem, and the method is called as "division downloading" since servers are not used in parallel. In this report, on the network with various condition described by delay and loss rate, we conducted simulation experiments using various combination of parameters such as the number of concurrent requests, the division number, and the number of streams. As a result, characteristics on divisional downloads using SCTP multistream have been clarified. |
