Implementation of requesting methods considering sequence control for progressive download using parallel TCP connections

Abstract (in Japanese) (See Japanese page) 
(in English) When realizing progressive download which replays a video file with simultaneously fetching divided partial les through multiple TCP connections with different performance, we have to alleviate out-of-order arrivals of partial files (blocks) that lead to reduction of users' playback quality of experience. In this report, we propose two methods: one is the requesting sequence control method which adjusts the requested block ID according to the past performance observed on each connection, and the other is the performance estimating method which is based on the response time of HEAD request checking the meta information of the target file before each download process. After implementing the proposed methods and evaluating them on a test bed environment and the real Internet, we have confirmed that the proposals can alleviate the out-of-order arrivals of partial files.
