New Internet2 Land Speed Record

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."

Land speed record

[Sycophant]

If I am not mistaken (and I could be, I suck at maths).

It traveled at about 3,345,350 KM/H, or about 5,352,560 MPH...

Does Internet2 use standard IPv6?

Why is a seperated network?

You think they are going to spend all that money on a serious research network only to let Joe Public use al, the bandwidth on pr0n?

Bandwidth Challenge SC2001

[anzha]

Every year there is a competition at the high performance conference (Supercomputing 2001 was this last one). It is entitled the 'Bandwidth Challenge'. This last year, NERSC took first place with a 3.3 gigabit/second sustained graphically represented simulation using seaborg.

Now, admittedly, it wasn't intercontinental, only from Oakland, Ca to Denver, Co....:D

good prices on workshops

[Moosifer]

Internet2 page has some events and workshops that look like they might be really good deals. I registered for the IPV6 3 day workshop at the University of Utah for only $100.00 - as long as it doesn't suck, that should be money well spent.

Some Calculations

[Traa]

The transfer rate of the new records calculates as follows: 625MB over 12,272km in 13 seconds = 590000 MB*Km/s = 0.590 TB*Km/s

When I drive home from work in a few minutes: 125TB (10^15 Synapses, Von Neumann et al.) at 85 Mph during rush hour (yeah, that manic...it's me) = 4.7 Tb*Km/s

The Boing full of DVD's calculates as follows: 4.7GB * 170.5 Cubic meters cargo space / 175 Cubic cm jewel case * 912 Km/h = 662,515Gb * 0.25Km/s = 1160 TB*Km/s

Even faster records: HDTV at 1.5Gbs

[kalgen]

The University of Washington has transmitted 1.5Gbps of HDTV across the country. I guess the new thing here is the intercontinental aspect. Here for the UW press release.

Re:It has to be said...

[AaronStJ]

Andrew Tannenbaum put it best with, "Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway."

This math is not done by me, but by Bonboard on Everything2 (search "Never underestimate the bandwidth of a station wagon full of quarter-inch tapes"):

13 Petabytes per second.

For comparison purposes, this is equivalent to about 650 strands of perfectly saturated, single-mode fiber optic cable.

This figure will, of course, vary depending on a number of factors. In order to compensate for your own rate of travel and storage media, simply fill in the blanks below to get your tally! It's fun for kids of all ages!
BW = (( WV / (TW * TL * TH ) ) * TC * WS / WL) , where

BW = bandwidth in bytes / second
WV = the volume of your station wagon, in cubic meters
TW = the width of each individual quarter-inch tape, in meters
TL = the length of each individual quarter-inch tape, in meters
TH = the height of each individual quarter-inch tape, in meters
TC = the capacity of each individual quarter-inch tape, in bytes
WS = the speed of your station wagon, in meters/sec
WL = the length of your station wagon, in meters

This figure assumes average instantaneous bandwidth down the length of the wagon; in reality, I would assume that the bulk of the data transfer would occur in the region nearest the trunk.
To get my figure, simply plug in: WV = 2.72, TW = 0.054, TL = 0.073, TH = 0.0105, TC = 35.0 * 10 ^ 9, WS = 26.8, WL = 4.75. These numbers are meant to describe a stuffed 2001 Subaru Outback doing 60MPH using 35GiB tapes of this form factor.

Re:that's fast

[Alan Partridge]

err... no it isn't. My little G4's internal SCSI array reads at sustd/peak 78/286 writes at 76/92. That's MB/sec so we're talking IRO R >600/>2200 W >600/>700. And this little array's nothing special, just a pair of Fujitsu MAJ's at 10K rpm with 4MB cache each on an ATTO UL3D twin channel host controller. Cost around a grand to install is all - there are WAY faster drives than those available now - awesome 15k rpm beasts than can top 60MB/sec sustained...
