Data Reservoir project
The University of Tokyo
-- Researchers and engineers from the University of Tokyo ,the Japanese WIDE Project, Chelsio Communications, Fujitsu Computer Technologies, LTD, NTT communications, APAN, JGN2, SURFnet, CANARIE, IEEAF, Pacific Northwest Gigapop, StarLight and Universiteit van Amsterdam together established the world’s longest 10 Gigabit per second circuit ever recorded for the transmission of internet data. The high bandwidth link connected two servers of the University of Tokyo’s Data Reservoir project through United States, Canada, Netherlands then back through United State to Tokyo. The length of this fiber optic path is approximately 33,979 km, spanning 17 time zones. The link was used to perform high-speed single TCP data transfers.
In the experiment, 7.21 Gigabits-per-second TCP payload bandwidth was sustained on a single stream with standard 1500-Byte Ethernet packets between two servers connected by this 33,979 km network. This international cooperative project pushes the boundaries of global research and education and lays a foundation for a new array of international research opportunities.
A pair of data-sharing Opteron systems from the Data Reservoir project, placed at Tokyo, each equipped with a Chelsio T110 10 Gigabit Ethernet adapter supporting TCP/IP offload were used for this experiment. A single TCP stream transferred data for over 30 minutes between the two hosts. In the calculation of bandwidth-distance products, which is used as a measure for the Land Speed Record, the distance is calculated as 30,000 km because of the rule of the Land Speed Record. The combined bandwidth times distance value is a new world record at 216,300 terabit meters per second. This is 45% greater than the previous Internet2 Land Speed Record IPv4 single stream achieved by the same group on Nov. 9, 2004, and is 17 % greater than the previous Internet2 Land Speed Record IPv4 multiple streams achieved on Nov. 8, 2004. Therefore this record is recognized as both IPv4 single and multiple stream class record. Network round trip time on this experiment is about 499 milli second.
Highlights of this achievement are as follows:
This experiment is partially supported by the Special Coordination Fund for Promoting Science and Technology, Ministry of Education, Culture, Sports, Science and Technology, Japan.
The demonstrations were made possible through the support of the following manufacturers, who have generously contributed their equipment and knowledge: Toyo Corporation, Foundry Networks, Cisco Systems, Bussan Networks, and Net One Systems.
