The prospect of downloading a feature film in seconds came a step closer today after Japanese scientists announced they had achieved a new speed record for transferring data over the internet.
The record - which involved sending a stream of data over a 30,000km network, the equivalent of three quarters of the earth’s circumference - achieved a speed of 9.08 GB/s, about 1,000 times faster than current top of the range broadband connections.
At that speed, a full-length feature film of 1.5 GB would be downloaded in matter of seconds. Most household broadband connections would take more than 40 minutes to download a film.
The benefits were not likely to be felt by regular internet users any time soon, however, because the record was set using a custom-built fibre optic network, which enables speeds far greater than the copper cables through which most homes connect to the internet.
It also used a ‘next generation’ internet protocol called IPv6, which has several benefits over the current protocol, IPv4, but is yet to be widely rolled out.
The researchers led by a team at the University of Tokyo set the record in December last year over a network which stretched from Tokyo to Chicago, on to Amsterdam, and then back to Tokyo via Seattle, a distance of 32, 372km.
For a period 20 minutes on a night they knew net traffic would be at a low - New Year's Eve - they streamed data at a speed of 9.08 GB/s, surpassing the previous record of 8.8 GB/s, which was set in February last year.
Dr Kei Hiraki, professor of computing science at the University of Tokyo who led the research, said: "These records are final for the 10GB/s network era because they represent more than 98% of the upper limit of network capacity.”
The increased speed had resulted from "several technical improvements," Dr Hiraki said, including more precise "pacing" of data and better "buffering capability," which resulted in less "packet loss."
The 'path' used for the record was custom-built fibre optic network used by universities and government agencies for research purposes.
A spokeswoman for internet2, a US-based consortium which helped develop the network, said that it was currently in the process of being upgraded to allow speeds of 100GB, which would allow films to be downloaded in fractions of a second.
"In order to deliver those kinds of speeds to consumers, however, you're talking about a significant investment in the existing infrastructure, and that's something that has to come from the network providers," the spokeswoman said.
Dr Hiraki said that he expected to achieve speeds of 40GB within 2 years, and 100GB in 6 years.
Asked whether he was already working on the next record attempt, he said: "Of course. But the method is still confidential."

Chris Sorensen has said it all, backbone technology alone will benifit. It'll be a while before they get UTP copper cable for us home users up to the 10Gb/s standard!
philip ryan, dublin, iRELAND
Wow. That's fast.
Chris Huff, Louisville, USA
Graham comments seem a little overly sceptical. Presuming his speed comment derives from a momentary confusion between bits & Bytes - the point he seems to have lost is that this technology is primarily going to benefit the backbone long before reaching us domestic users.
Chris Sorensen, stockport, uk
Talking about the speed for downloading a move assumes first that there are movies worth down-loading, that the rights owners will allow people to download them, and that the storage capacity of the person downloading the movies will be able to handle it easily. This leaves open the way that the people who download the movie have to actually watch it and that they will have people who want to watch it with them.
The technical stuff is all beside the point. The point is the end user and what he or she or them want to do with all this wonderful capacity. Having said this, every technical breakthrough has been greeted with skepticism about how it would be useful and has been proved wrong, but usefulness is what's important. I have friends who watch nothing but explosions and gunfights interspersed with short sex scenes, car chases, and fights, all with cheesy special effects and no plot or characters.

The days R longer in Summer, cuz its hotter,
&
the days R shorter in winter , cuz its colder.
now don't that make sense yet?
Godzilla, Isippysakki, Japan
Surely this is complete nonsence ?
There are already over 10Gbit connections in use today. Most ISP's use faster fibre links internally to transfer data between nodes.
I feel this should be taken down as it proves nothing and isnt even worth thinking about.
No one will have these type of speeds at home any time soon.
If everyone had this then the internet would probably grind to a halt as the backbone wouldnt be able to handle the amount of traffic. Let alone the webservers out there failing to provide the content requested in a fast enough manner.
Graham, Gloucester,
To help people understand what Al posted at the bottom of these comments; GB refers to a Giga Byte where as Gb refers to a Giga Bit. As there are eight bits in each byte, the author of this article has actually commented on the speed being eight times faster than the record which was actually made.
HOpe that made sense for you guys. However, on topic, if any of this, which is clearly does, relies on ISP support and help, I think the UK will have to wait for ALONG time before seeing any of this in action.
Simon Tomlinson, Sheffield,
The factor of 8 with GB versus Gb as the unit of measure may not greatly bother those still boggling with the difference between optical fibres and fibre optics, if not the mind-numbing magnitude of speed transmissions possible with such technology, especially with the possibility of location confusion that the initial GB may entail..
dr venables preller, Warminster, UK
Could Dave from London please post only English comments. I have no idea which language has been used in his posting.
rob, london,
I think you need to learn to distinguish GB (gigabyte) from Gb(gigabit). The transfer speeds you quote throughout your article are eight times the actual claims of the Japanese.
neil f, Harrow,
Please, all jounalists, stop referring to the transmission medium as a "fibre optics system" . It is a "optical fibre system" .
L Hayball, Nottingham,
the guy below thinks he knows it all(what a gimp)!
i read the essay bout this and it reminds me how artist shem booth made the painting light emission reality matrix, The paintings about in the future post electric era were a communication grid across the universe which is faster than light(or a different method not, did anyone see the film stealth were there AI computer runs at 10 Tera bytes pr second
were not far away from that, although im sure area 51 that stuff ;)
Dave, London, uk
Ermm ... I think you're getting your bits and your bytes mixed up here. The speed record they have set is 9.08 Gb/s ... the lower case 'b' meaning it is actually 8 times slower than 9.08GB/s. However, the rest of the facts in the article make sense dispite this.
