Something to wish for

The European Organisation for Nuclear Research, CERN, said the feat, doubling the previous top speed, was achieved in a nearly 30-minute transmission over 7,000 kms of network between Geneva and a partner body in California.

CERN, whose laboratories straddle the Franco-Swiss border near Geneva, said it had sent 1.1 Terabytes of data at 5.44 gigabits a second (Gbps) to a lab at the California Institute of Technology, or Caltech, on October 1.

This is more than 20,000 times faster than a typical home broadband connection, and is also equivalent to transferring a 60-minute compact disc within one second -- an operation that takes around eight minutes on standard broadband.

Using current technology, a DVD -- or digital video disc -- film of some 90 minutes length takes some 15 minutes to download from the Internet.

Olivier Martin of CERN, which is also the European Laboratory for Particle Physics and home to a hugely ambitious particle-smashing project to unravel the fundamental laws of nature, hailed the feat as a milestone.

It would bring closer researchers' final goal of abolishing distance and making collaboration between scientists around the world efficient and effectively instantaneous, he said.

Harvey Newman of Caltech, another of the world's major research centres, said the achievement boosted hopes that systems operating at 10 gigabits per second "will be commonplace in the relatively near future."

It'll be a lonnnnggg time before we see this.

Has anyone ever downloaded a 60 min CD in 8 minutes using "standard broadband"? (I know they're probably talking about America but according to my calculation it ain't possible, about 3 hours on a 512kb/s). I assume they mean about 650 MB.

i think by standard broadband they mean the maximum speeds dsl can achieve where DSL is the the normal broadband.
They obviously had to create a new type of system to transfer data at those speeds.

I'm not sure where you got 3 hours from. 512kb/s is about 3MB a minute - that's make about 20 minutes for a CD, or close enough to 8 if you get a CDs worth of songs in MP3 format.

(Of course, actually getting 512kb/s is another matter).

Correct me if I'm wrong but it's 8 bits in a byte isn't it. So theoretically that's:
60 kB/s
3.6 MB/min
216 MB/hr

I was basing my calculation on a 650 MB file which would take about 3 hours. That's assuming I haven't messed anything up. Of course now that I think about it an average music CD is about 60 MB so that'd take about 17 min (at 512kb/s).

is about 3MB a minute - that's make about 20 minutes

I think you'll find that 3MB x 20minutes = 60MB = 180MB /h
which = about 4 hrs for a CD.
This ties in to my download speeds

3MB a minute for 20 minutes is 60MB. You meant 200 minutes. Either way, this new system is hella fast...

I was just checking if anyone was paying attention - (yeah, right )

Sorry about that - I'm not sure what I was thinking of when I calculated that 20minutes at 3MB/min would give you 600MB. It must have been something I ate.

of course of course, i just wanted to show that i was awake

16 seconds for a meg at full 64kilobytes a second. it would take 10400 seconds for a full 650 megabyte CD. At maximum speed for standard DSL connections is about 10 MegaBits, this would make it 20 times faster than the standard 512 making the download time one 20th of 10400 which is 520 seconds or 8 minutes and 40 seconds.

i thought vDSL could go to 50mbit or something?
Tho that wouldnt really be standard dsl
