For the first set of IPv6 records, a team from the University of Tokyo, WIDE Project, NTT Communications, JGN2, SURFnet, CANARIE, Pacific Northwest Gigapop and other institutions collaborated to create a network path over 30,000 kilometers in distance, crossing 6 international networks - over 3/4 the circumference of the Earth. In doing so, the team successfully transferred data in the single and multi-stream categories at a rate of 7.67 Gbps which is equal to 230,100 terabit-meters per second (Tb-m/s). This record setting attempt leveraged standard TCP to achieve the new mark.
Mind you, those crazy Japanese do this every year between christmas and newyear... ;) Most of the pipes they used also carry other research traffic throughout most of the year... This year was even more cumbersome because of some issues with the OC192's between Amsterdam and the USA...
Kind regards, JP Velders
we -love- the crazy Japanese doing this kind of stuff. the US folks seemed to have lost momentum in the past decade. while the pipes do get re-purposed on a regular basis, they do tend to shake out interoperable problems, as you note above. me, i await the spiral loop that includes the southern hemisphere ... --bill
