Researcher Runs IP Network Over Xylophones 83

joabj writes "Following up on experiments of running Internet Protocol(IP)-based networks with carrier pigeons or bongos, UofC grad student R. Stuart Geiger has demonstrated that it is possible to transmit simple ping requests across two computers using people playing xylophones. Throughput is roughly 1 baud, when the participants don't make any mistakes, or get bored and wander off. The OSI encapsulated model of networking makes this project doable, allowing humans to be inserted at Layer 1, the physical layer. Vint Cerf wasn't kidding when he used to say, 'IP on Everything.'"

    I remember doing "networking via scraps of paper" at school.

    Writing silly notes since kindergarten and then actually implementing some real protocol in computing classes.

    Then a couple of years later an LED, a bit of fibre and an LDR and we were building "fibre networks".

    Mind you, this was two decades ago.

    Looking even at the "cool" projects which come out of MIT undergrads, I get the impression that almost all children are exposed to absolutely nothing interesting whatsoever before the age of 18.

        • In the public grade schools in Hawaii, the class will share about four textbooks on any given subject, and the state mandates and actually teaches toward state tests with state lesson plans and quizzes that are frequently wrong. They mark the kids as wrong when they get things right, and then tell them "you were right but I have to mark it lower because the state's answer is X."

          And I don't mean normal smarter-than-the-test wrong, I mean things like singular v. plural.

    • I remember doing "networking via scraps of paper" at school.

      When I visited the Miraikan Museum in Odaiba, Toyko, back in ~2005 they had a mechanical IP network that routed 2 byte messages of black and white wooden balls over rails and Archimedes screws. The first byte was the "IP" address (I think there were 4 or 5 nodes) and the second byte was the message. You set up your message in the staging area of your workstation, then pulled the release lever. The balls would roll down the track past an eye that would read the colors and various gates would be opened/clo

      Speilberg made $337,700,000. This guy will die a virgin. Big difference.

      • Dude, why did you post anonymous. You would have had a great moderation war.

        Those who see the humor (and fact) in wrote you wrote would mod you up.
        Those see Spielberg as a deity and will do anything to appease him, and mod you down.
        Those who the virgin comment hits just a little too close to home would mod you down.

        My gut instinct is that you would have had at least a couple dozen moderations, and landed at a nice solid "+4 troll"

  • 1 baud seems quite slow. Using the different notes to code diffent byte values would allow you to transmit data quite quickly. If you have 8 diffferent notes, then 2 consecutive notes can do 1.6 million different combinations. That's equivalent to 3 bytes. 2 notes could easily be played in 1 second rso 3 baud would be simple. Bring it up to 32 keys and the baud rate could go up quite highroad. You just have to encode it properly.

      The baud rate is insignificant of throughput, it's not clear why it was even mentioned, especially in relation to throughput. Each note encodes 4 bits (a hex digit), so although it does run at 1 baud, the system runs at 4 bps.

      Your math is way off. With 8 notes, each encodes 3 bits; two notes allow 64 different combinations (not 1.6 million!), or 6 bits.
    • by Anonymous Coward

      1 baud means one symbol per second, not one bit per second. If there are only two symbols in the alphabet (for example two notes), then 1 baud results in 1bps, but if there are more symbols, the bitrate can be higher.

    • 8 notes is three bits each, I don't know how you got to 3 bytes from two consecutive notes...

      Even two simultaneous notes would only be six bits.

    • If you have 8 diffferent notes, then 2 consecutive notes can do 1.6 million different combinations.

      Well, no.

      Actually, 2 octal digits can do 64 different combinations.

    The article states that the musical instrument has "aluminum keys". From http://en.wikipedia.org/wiki/Glockenspiel :

    "[A glockenspiel] is similar to the xylophone; however, the xylophone's bars are made of wood, while the glockenspiel's are metal plates or tubes, thus making it a metallophone."

      And for those who slept in biology, xylem tissue transports water and dissolved nutrients, in a tree it is the wood. The word comes from the Greek xylon, which means wood. So a xylophone must be wooden.
      • Originally xylophones were all wooden, and the expensive ones still are, but many are made of synthetic material now.

        As a band director that teaches percussion it drives me nuts when people call a Glockenspiel (or bell set) a xylophone. I think it's caused by some of the toys that are available for little kids that are mislabeled.

  • Stuart Geiger has demonstrated that it is possible to transmit simple ping requests across two computers using people playing xylophones.

    Was there ever any doubt that this could be done? It's the same as that carrier pigeon IP thing - it was always going to work. Has it taught us anything new?

  • Baud is a measure of symbols per second, so it's meaningless unless the amount of information per symbol is defined.

    In this case, it turns out that a symbol is a hexadecimal value, so the data rate is about 4 bits per second.

  • With today's DSP technology, FFT algorithms, and a bank of solenoids, two computers could, in theory, transmit data via xylophones a LOT faster than one baud!

    FFT analysis on the receiving ends determines which notes are being played and when, even simultaneously. By using notes unique to each machine, both can be playing and receiving simultaneously. It would be quite noisy, but would definitely work.

    It would also be a good idea to "damp" the chimes, to dramatically reduce the audio decay rate. This would a

  • "The OSI encapsulated model of networking makes this project doable". The OSI model never made anything doable. Encapsulation was invented long before OSI came along and the seven layers never had any impact on the basic Internet protocols. The idea of "frameworks" is about as close as anyone got to anything like the OSI seven-layer cake which has always been an abomination and was never responsible for the development of anything.
