Slashdot Mirror
Net Speed Record Smashed
BrianWCarver writes "The BBC is reporting that scientists have set a new internet speed record by transferring 6.7 gigabytes of data (the equivalent of 4 hours of DVD-quality movies) across 10,978 kilometres (6,800 miles), from Sunnyvale in the US to Amsterdam in Holland, in less than one minute. Average speed: more than 923 megabits per second, or more than 3,500 times faster than a typical home broadband connection. The data was sent across the Internet2 network. Stanford Linear Accelerator Center (Slac) Computer Services participated in the record-breaking event. Slac has an interest in such high-speed transfers as they have accumulated the largest known database in the world, which grows at one terabyte per day."
If I have anything to do with it my broadband will NOT be 3500 times slower.....I'm moving to amsterdam!

I'd like to know what media they used that could write that much information in 1 minute.
You just got to love how all internet trafic of today is measured in movies. ;)
ahh, it actually was 4 hours of DVD-quality movies...
It's supposed to be completely automatic, but actually you have to press this button.
The best part is since internet2 is a private network, no mainstream users are going to benefit from it's incredible speed. Hooray!
Stanley Feinbaum, professional journalist and master debater! God bless the USA!
They transferred all this data over Internet2 and the writeup says "...set a new internet speed record ...". Isn't that cheating?
That's like saying "Our new car can go 6000 mph! (on a conveyer belt moving at 5950 mph).
Tommorrows headline on slashdot?
If they are using that much bandwidth they must be pirating something.
I've said that no transmission method of bandwidth will ever exceed, in my lifetime, the bandwidth of a station wagon full of backup tapes.
"A simple calculation will make this point clear. An industry standard 8mm video tape (e.g. Exabyte) can hold 7 Gigabytes. a box 50x50x50 cm can hold about 1000 of these tapes, for a total apacity of 7000 Gigabytes. A box of tapes can be delivered anywhere in the US in 24 hours by Federal Express and other companies. The ffective bandwidth of this transmission is 56,000 gigabits/86400 sec or 648 Gbps, which is 1000 times better than the high-speed version of ATM (622 Mbps). If the destination if only an hour away by road, the bandwidth is increased to over 15Gbps."

Yes, OC192 is faster, but I've never heard of a single computer being able to push that much data that fast over a single connection.
A few years ago SGI did a test where they leased a piece of cross-country dark fibre for a day and ran GSN over it. That's a single connection-- using ST, not TCP-- from one computer to another computer, RAM to RAM. They pegged over 790 MB/s (that's a big B, as in megabytes per second), and sustained it for hours. And, just to reiterate, this was from one computer to another computer, without any fancy-schmancy multiplexing or anything. This was the ST equivalent of a single FTP transfer.
I can't find any documentation of this test on the web, but I saw it with mine own eyes. One end of the connection was in Herndon, VA, (where I was) and the other was out west someplace.
The SLAC test did 900+ Mb/s over a switched network, which is darned impressive. It's undoubtedly a record for a public switched connection. But don't go thinking it's an absolute land speed record or anything like that.
