New Internet2 Land Speed Record 338
SquadBoy writes "An international team set a new record for Internet performance by transferring the equivalent of an entire compact disc's contents across more than 7608 miles (12,272 km) of network in 13 seconds. The rate of 401 megabits per second achieved in transferring 625 megabytes of data from Fairbanks, Alaska to Amsterdam in the Netherlands is over 8000 times greater than the fastest dial-up modem."

that's the reason why that WD ATA133 drive with 8MB cache scores so great, it can burst up to 8MB at up to 133MB/sec
Not quite. The only ATA/133 drives in existance are made by Maxtor. Those 8MB cache Western Digital drives are built with ATA/100 interfaces. Not that it matters to any measurable degree, the Maxtors don't actually benchmark any better when run off of an ATA/133 controller vs an ATA/100.

But as long as you are, why aren't DVD's an acceptable format to store the data in once it arrives? I was kinda assuming that the data we wanted to transfer in the first place was on DVD... After all, what could more bandwidth be used for but movie sharing?
But whatever method I used, I could certainly do it faster than a single average hard drive. If I can fill 100 box cars with dvd's, I can buy ten thousand DVD writers, and ten thousand readers. Or hell, just buy enough hard drives to make a direct copy, ship those, and plug them in at the other end.
But now I'm curious.
Let's take a box car that is 40'x10'x15'. Not too big. Let's take a jewel case to be 6"x8"x0.5", which is slightly overestimating the volume, but the math is easier.
So all I need are a few DVD manufacturing facilities, and I'm pretty sure I can beat that.
Probably the hardest part would be finding 372 petabytes of non-redundant information to transfer. Unless you -want- a few million copies of Titanic.

For me to get time on the FedEx petabit jumbo jet costs what, $10E-10/bit? Now presume that internet 2 will have a hundred nodes, and will cost ten billion (optimistic on both counts) so about a hundred million per node or about ten million per node per year. So one second costs about 3 cents, and I get 0.4 gig for it presuming there is the demand for full utilization.
So where is the scientific reason for spending a hundred times more per bit? If it's a big shipment, I can wait for the plane. If it's a small shipment, I can wait for good old internet 1. If it's interactive, I should fly myself to the computer that's doing the crunching or upload the code to my local platform. I have yet to see a legitimate scientific application for this. Maybe there's a futuristic entertainment angle to internet 2, but should NSF be funding ultra-luxury entertainment?

Anyway, in which real-world instance does the delay of ftping or FedExing data have sufficient incremental costs that justify even the operating expense of internet 2, which is to generously presume that it actually ends up in substantial use rather than as an expensive empty pipe. (Waxahatchie anyone?)
Here's another way to look at it. If I'm running a research institution researching anything but internet 2 itself, why would I prefer an internet 2 node to the gigantic computing cluster I could afford instead right onsite?
A sensible cost-benefit analysis would have to prove that the cost of generating the bits remotely and then shipping them is substantially less than the cost of generating them locally.
If compute power gets cheaper faster than bandwidth, and since computers are pretty much indifferent to where they are located, I can't see how to formulate a sensible argument in that vein.
Why should I pay more for the pipe than the guy on the other end paid for his computer that I'm borrowing?
The only way this makes sense is if bandwidth is cheap and compute power is scarce. Correct me if I'm wrong, but this seems to me wrong on both counts.
