| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this report, we discuss a video server system that performs streaming transmissions of Consumer Generated Video (CGV) files. The CGV files are placed in iSCSI (i.e.,SCSI over TCP) storages at each owner's home, and the iSCSI storages are connected from one video server on demand. To guarantee QoS, a managed IP network is used between the video servers and iSCSI storages. The managed IP network means the Next Generation Network (NGN). Since iSCSI uses the TCP protocol, the network delay influences the iSCSI throughput largely. The network delays between video servers and iSCSI storages depend on the locations of the servers and storages, and the network topology. Although the iSCSI storages have different network delays for the video servers, it is important to design the system so that the streaming transmission quality does not depend on the network delays. To ensure the fairness of streaming transmissions, we adopt a technique to dynamically control the number of TCP connections in the iSCSI protocol. Simulation results show that the CGV file streaming transmission quality at 3 Mbps is stable on the condition that the Round Trip Time (RTT) between servers and storages is 100 ms. |
