Researcher Runs IP Network Over Xylophones
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.
IP doesn't mean TCP/IP. The TCP half is what does the error control. Therefore, a ping wouldn't have error correction... just "appropriately replied/didn't reply appropriately"

Error detection is a Layer 2 responsibility. TCP only does sequence numbers and resends lost packets.

Sigs. We don't need no steenking sigs.
Play major chords. If a note is incorrect then the chord is dissonant and you have an error condition.
Are YOU using the TOOL, or is the TOOL using YOU? Think about it!
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."
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.

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.

"'IP on Everything." Sounds like his office is a really disgusting place.
War is one of the most horrible things a human can be exposed to. And one of the worlds largest industries.
That's a no-go -- the trademark is already registered to Apple's biological weapons division.
Because it's fun?
In California, we call it UC Berkeley.
i.e. yoo see burr clee, and even that is incorrect, as the town and the school where named after Bishop Berkeley of "if a tree falls in the forest and no one is around to hear it, does it make a sound?" fame. His name is pronounced BAR clee.

Internet Protocol over Xylophone Players (IPoXP) situates humans at the lowest layers of the Internet. Read the full paper at http://www.stuartgeiger.com/ipoxp.pdf. A project by R. Stuart Geiger, Yoon Jeong, and Emily Manders at the University of California, Berkeley. Presented at alt.CHI 2012.
Really they didn't implement IP-over-xylophone -- you cannot, because there is no provision in the IP standard for framing between packets. They implemented some as-yet-undisclosed link layer protocol, and then ran IP over it. They could just as easily have run DECNET. Since they gave no details of the link layer protocol, we don't know if it had checksum support.
Someone had to do it.
As a followon to my rfc1149 and rfc2549, I considered doing IP over black holes: if you carefully control matter being dropped into a black hole, you can modulate the huge X-ray emissions as the matter is ripped apart. This would be detectable over huge distances.
