The Internet2 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.
“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.”
