IP over Avian Carriers

In data processing IP over Avian Carriers ( IP on Avian Conveyers ) is a method of transport of traffic IP (Internet Protocol) by birds such as carrier pigeons. IP over Avian Carriers was initially described in the RFC 1149 like a humorous document ordered by the Internet Engineering Task Force . This one was written by D. Waitzman and was carried out for fish of April of 1990.

Ten years later, on April 28th, 2001, IP over Avian Carriers was implemented by the Bergen Linux User Group. They sent 9 packages on an approximate distance from 5km, each one carried by only one pigeon and containing a ping (ICMP Echo Request) and received 4 answers. With a percentage of lost packages of 55%, and a response time between 3000 and 6000 seconds, IP over Avian Carriers thus does not seem suitable to be employed in traditional networks IP.

Waitzman improved the description of its protocol in the RFC 2549, IP over Avian Carriers with Quality off Service (April 1st, 1999).

Comparison of band-widths

Thanks to the development of technologies with memory flash, the transfer of information by carrier pigeons could have an advantage compared to the traditional means of transfer, on the condition of tolerating the latency time in exchange of this very high band-width. For example, for a distance of more than 50km a pigeon can carry more 10Go data in approximately 1 hour, which can be much faster than a traditional connection ADSL. But one has to expect losses of data. In addition if the pigeons would be used for that, the communication will not thus be done more by IP.
