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

        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.
    • Can it?
      that's 6,646 cd's worth of stuff in 24 hours.
      Your plane would move more than that.

      So if your destination and source media are CD, the airplane is faster.
      If it's NOT, the airplane is much slower, factoring in the time it will take to read all those cds.

    • no......

      (B = bytes, b=bits)



      625MB * 8b/1B = 5000 Mb / 401Mb/sec = 12.5 sec



      401Mb/sec * 1048576Mb/1b = 420478976b/sec



      You CAN'T derive physical speed from that. Bits travel at the speed of light, and bits per second is dependant on the lenght of time each bit lasts, in this case, a fraction of a nanosecond.

      • Well, you have a metric, which is bandwidth multiplied by distance, in this case 4.9Pbit*m/s... you can get the equivalent metric by sticking 35343 CD-ROMs worth of data in the back of a van and driving it at 100km/h down the freeway. Isn't statistics fun? :)
      • Oh yes, each bit much have lasted at least 40ms -- the time it takes light to travel 12272km in a vacuum. In an optical fiber it would take even longer. Now, if you're transmitting at 401Mbit/s, and assuming the speed of light in vacuum, each bit is just about 75cm long, which means it swoshes by an observer (such as the receiver) at about 2.5ns -- not even that is "a fraction of a nanosecond."

    Yeah, but how many Libraries of Congress is that? Until they release their accomplishment in Libraries-of-Congress-per-second, it means absolutely nothing to me, or anyone else. Right?
    • If a LOC is 10 terabytes, then 700 megs (approximately), is about .00007 Libraries of Congress. (Don't get me started about bips and bits).

      The informaton that the LOC is 10 terabytes comes from the Data Powers of Ten [caltech.edu] page. Whether or not this is entirely accurate, I'd be willing to bet that a lot of reporters and such use it as a reference. They're probably good ballpark numbers. To quote a bit from the section of the page that includes the LOC:

      Terabyte (1 000 000 000 000 bytes)
      • 1 Terabyte: An automated tape robot OR All the X-ray films in a large technological hospital OR 50000 trees made into paper and printed OR Daily rate of EOS data (1998)
      • 2 Terabytes: An academic research library OR A cabinet full of Exabyte tapes
      • 10 Terabytes: The printed collection of the US Library of Congress
      • 50 Terabytes: The contents of a large Mass Storage System
      • More accurately (and relevantly), the transfer rate of 401 megabits per second amounts to 0.00005 LOC/s, or 4.33 LOC/day. This is of course assuming the reference LOC size of 10 terabytes (not tebibytes).

    This article, I feel is more than a little vauge. What did they use to transfer? Was it just over electrical/telephone lines, or did they use optics? What kind of compression was used, and what kind of signal boosters/optical repeaters were used in sending this. All of these items could be used to affect the speed of transfer, and well, the article just doesn't say. I mean in theory, one could build a router from parallel to serial that could take data at 9.6 terabits/sec. How are they actually measuring things? Just the time between there and here? Using full optical lines, wouldn't they be able to set the record at c * the index of refraction of the fiberoptic line? It would just be a matter of putting all the data into one block of light.

    Also the article suggested only one way communication, what happens with error checking and such?

      You are speaking theoretically.

      Yes, you could send data much faster than this over fiber. We do it in labs all the time. HEck, we do it in networks over copper all the time (GigE..)

      This is an actual working network, and they send the data from Alaska to The Netherlands at 400mbps. That is fantastic.

    Assuming a perfect light speed connection and a straight path with no delays en-route...

    The data was flowing at a rate of 2.33 bits per foot which works out to 11 Megabytes in flight at all times. That's one hell of a juggling act.

  • We've already established that FedEx wins on bandwidth, now what about cost per bit.

    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?
