Abstract

We developed a remote storage transmission system that automatically gathers high-quality video signals at the moment of an earthquake in best-effort IP network. The system achieves higher transfer rate and network bandwidth utilization efficiency using parallel TCP connections. We evaluated the transfer rate of the video signals and the required time from the trigger of earthquake information to the transmission completion of the video signals. The system achieved approximately 60 Mbps of transfer rate and approximately 12 seconds from the trigger of earthquake information to the transmission completion of the 1 minute video signal in actual FTTH network.
