Some white-coat, huge-brain scientists in Tokyo managed to break the speed record for Ethernet data communication using IPv6. The record was reported just now by the Internet2 consortium, the organizers of the competition.
The data transfer took place between Tokyo, Chicago, Amsterdam, Seattle and then back to Tokyo, covering a total distance of 30.000 km. It crossed six different networks with the help of partners like JGN2, NTT Communications and SURFnet.
The team actually broke the record twice, first using standard protocols and obtaining a speed of 7.67 Gbit/s then two days later using modified protocols and obtaining a speed of 9.08 Gbit/s.
No the race is on for the 100 Gbit/s record to be achieved after the release of the new Ethernet specifications.
