Anue Systems Contributes to World Records for Fastest IP Network

Teams led by University of Tokyo break Internet2 Land Speed Records after using Anue Network Emulator

Austin, TX – April 3, 2006 — The University of Tokyo made headlines last month when it was announced that they led an international team to set the world records for the highest bandwidth end-to-end IP Network. Behind this effort were months of preliminary evaluation in the University of Tokyo lab using the Anue Network Emulator.

The Internet 2 Land Speed Record competition for the highest bandwidth end-to-end networks is an open and ongoing contest. Records are set based on how much bandwidth is used and how much distance is traveled using standard TCP/IP protocols. The University of Tokyo led teams now hold the current world records in both the IPv6 and IPv4 categories, having transferred the following over a distance of 30 thousand kilometers:

* 585 gigabytes at an average rate of 6.18 Gbps using IPv6, and
* 1485 gigabytes at an average rate of 7.99 Gbps using IPv4.

The intercontinental path used in this record-setting event started and ended in Seattle and included multiple international networks. This entire path created a round trip latency of 500 milliseconds. In order to model this network latency prior to the winning performance, the Graduate School of Information Science and Technology at the University of Tokyo conducted evaluations using a 10 Gbps Network Emulator from Anue Systems. The Anue Network Emulator provided full line rate delay on their 10-GE WAN signals regardless of frame size without modifying the signal. The Anue Emulator was also used to create various error conditions real time to model unfavorable network behavior in the lab setting.

“What was most useful about the Anue Emulator was that it inserted a perfectly jitter-less delay,” explained Kei Hiraki, a professor at the University of Tokyo. “This allowed us to determine whether a reduction in bandwidth was caused by round trip time or by some other factors such as jitter somewhere in the network. As a result, we concluded that jitter on the actual network is a major factor in the reduction in efficiency in ultra long distance Internet communication. The precise and accurate delay inserted by the Anue emulator was instrumental in identifying jitter as the cause.

“It is an honor to have worked with Dr. Hiraki and his team at Tokyo University to help them set the world land speed record,” said Hemi Thaker, President and CEO of Anue Systems. “This project further demonstrated Anue’s ability to provide ten gig emulation performance to our leading edge customers.”

Internet2 is a consortium led by over 200 universities, including MIT, working in partnership with government and industry to accelerate the creation of tomorrow’s internet.
