Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, video streaming services using TCP as a transport
layer protocol represented by YouTube have been popular, with rapid
increase of the network bandwidth. Congestion control of TCP increases
the congestion window until a packet loss is detected. Therefore,
the video streaming over TCP sends packets
to a network at a higher speed than the video playback speed that takes
the bandwidth of other competing traffic unnecessarily.

In this report, we first investigate the data transfer mechanism of existing
video streaming services using TCP and show
that the existing video streaming services perform data transfer at the
extremely higher rate than the video playback speed. Then, we propose
the data transfer mechanism for video streaming over TCP that does not
take the network bandwidth excessively by controlling the data
transfer at an application layer.

The proposed mechanism acquires the TCP state variables from the source
host TCP, and estimates network congestion status. Moreover, the
amount of buffered video data is acquired from a destination
host. By adjusting the amount of data passed to a source host TCP in one round-trip time
based on the network congestion status and the amount of buffered video data,
the proposed mechanism controls the data transfer speed.
Simulation results show that the proposed mechanism decreases the frequency of
buffer underflow at the destination host, and does not take the bandwidth of background traffic.
