IP over Avian Carriers

On 28 April 2001, IPoAC was implemented by the Bergen Linux user group, under the name CPIP (Carrier Pigeon Internet Protocol). They sent nine packets over a distance of approximately , each carried by an individual pigeon and containing one ping (ICMP echo request), and received four responses. during debates about HADOPI. == Risks ==

In December 2005, a Gartner report on bird flu that concluded "A pandemic wouldn't affect IT systems directly" was humorously criticized for neglecting to consider RFC 1149 and RFC 2549 in its analysis. Known risks to the protocol include: • Carriers being attacked by birds of prey. RFC2549: "Unintentional encapsulation in hawks has been known to occur, with decapsulation being messy and the packets mangled." • Carriers being blown off course. RFC1149: "While broadcasting is not specified, storms can cause data loss." • The absence of viable local carriers. RFC6214: "In some locations, such as New Zealand, a significant proportion of carriers are only able to execute short hops, and only at times when the background level of photon emission is extremely low." This describes the flightless and nocturnal nature of kiwi. • Loss of availability of species, such as the extinction of the passenger pigeon. • Disease affecting the carriers. RFC6214: "There is a known risk of infection by the so-called H5N1 virus." • The network topologies supported for multicast communication are limited by the homing abilities of carriers. RFC6214: "... [carriers] prove to have no talent for multihoming, and in fact enter a routing loop whenever multihoming is attempted." • Carriers are susceptible to the man in the middle attack. == Other avian data transfer methods ==

Rafting photographers already use pigeons as a sneakernet to transport digital photos on flash media from the camera to the tour operator. Over a distance, a single pigeon may be able to carry tens of gigabytes of data in around an hour, which on an average bandwidth basis compared very favorably to early ADSL standards, even when accounting for lost drives. On March 12, 2004, Yossi Vardi, Ami Ben-Bassat, and Guy Vardi sent three homing pigeons a distance of , "each carrying 20–22 tiny memory cards containing 1.3 GB, amounting in total of 4 GB of data." An effective throughput of was achieved. The purpose of the test was to measure and confirm an improvement over RFC 2549. Winston beat the data transfer over Telkom's ADSL line, with a total time of two hours, six minutes and 57 seconds from uploading data on the microSD card to completion of download from the card. At the time of Winston's victory, the ADSL transfer was just under 4% complete. In November 2009, the Australian comedy/current-affairs television program Hungry Beast repeated this experiment. The Hungry Beast team took up the challenge after a parliament session wherein the government of the time criticised the opposition for not supporting telecommunications investments, saying that if the opposition had their way, Australians would be doing data transfer over carrier pigeons. The Hungry Beast team had read about the South African experiment and assumed that, as a developed Western country, Australia would have higher speeds. The experiment had the team transfer a 700 MB file via three delivery methods to determine which was the fastest: a carrier pigeon with a microSD card, a car carrying a USB stick, and a Telstra (Australia's largest telecom provider) ADSL line. The data was to be transferred from Tarana in rural New South Wales to the western-Sydney suburb of Prospect, New South Wales, a distance of by road. Approximately halfway through the race, the internet connection unexpectedly dropped and the transfer had to be restarted. The pigeon won the race with a time of approximately 1 hour 5 minutes, the car came in second at 2 hours 10 minutes, while the internet transfer did not finish, having dropped out a second time and not coming back. The estimated time to upload completion at one point was as high as 9 hours, and at no point did the estimated upload time fall below 4 hours. A similar pigeon race was conducted in September 2010 by tech blogger (trefor.net) and ISP Timico CTO Trefor Davies with farmer Michelle Brumfield in rural Yorkshire, England: delivering a five-minute video to a BBC correspondent 75 miles away in Skegness. The pigeon (carrying a memory card with a 300 MB HD video of Davies having a haircut) was pitted against an upload to YouTube via British Telecom broadband; the pigeon was released at 11:05 am and arrived in the loft one hour and fifteen minutes later while the upload was still incomplete, having failed once in the interim. ==See also==
