Researchers from Tokyo University have broken internet downloading speed records twice in the space of just two days.

A team sponsored by Internet2, a research company run by 200 US universities, began their record attempt by creating a network path of over 30,000 km, crossing six international networks and covering three quarters of the Earth's circumference.

They first transferred data at a rate of 7.67 gigabytes per second (Gbps), equal to 230,100 terabit-metres per second (Tb-m/s). By contrast, a standard UK broadband household connection downloads at about 8 megabytes per second (Mbps).

The very next day, the team adapted their techniques and was able to achieve a throughput of 9.08 Gbps, equal to 272,400 Tb-m/s.

Dr Kei Hiraki, professor at the University of Tokyo and land speed record team leader, said: "These records are final for the 10 Gbps network era because they represent more than 98 per cent of the upper limit of network capacity.

"Through collaboration by a number of institutions, we have demonstrated the ability to overcome the distance and achieve this newest mark."
