This paper examines the influences of network latency and packet loss on the playback quality of MPEG video on iSCSI disks. The paper also explains the relationships between the video-playback quality and the transmission speed, average bit rate of video, file-reading block size, and receive window (RWIN) size. Experimental results indicate that the additional delay at which the average MU rate suddenly falls down increases as the RWIN size becomes larger up to the amount of read-response data plus the number of bytes of the iSCSI response header. In addition, we can reduce the deterioration in the video-playback quality by enlarging the file-reading block size.
