Subject: from the academic side of the house

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,

        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 ...
