We propose here a video server system that streams transmissions of consumer generated video (CGV) files. The CGV files are placed in Internet small computer system interface (iSCSI, i.e., SCSI over TCP/IP) storage devices at each individuals home, and these storage devices are connected to one video server on demand. Because iSCSI uses the TCP protocol, the network delay greatly affects the iSCSI throughput. Although iSCSI storage devices have different network delays for video servers, it is important to design the system so that the streaming transmission quality does not depend on network delays. To ensure the scalability of streaming transmissions, we use a technique to dynamically control the number of TCP connections in the iSCSI protocol. Simulation results showed that the CGV file streaming transmission quality at 3 Mbit/s was stable when the round-trip times between the servers and the storage devices were less than 100 ms.
