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.

The next day, the team used a modified version of TCP to achieve an even
greater record. Using the same 30,000 km path, the network was able to
achieve a throughput of 9.08 Gbps which is equal to 272,400 Tb-m/s for both
the IPv6 multi and single stream categories. In doing so, the team surpassed
the current IPv4 records, proving that IPv6 networks are able to provide the
same, if not better, performance as IPv4.
