The IP over Avian Carriers ( IPoAC ), German about Internet protocol by flying carriers , is a jocular network protocol for wireless point-to-point connections by means of carrier pigeons .
It was originally specified in RFC 1149 on April 1, 1990 and expanded to include a QoS component in RFC 2549 on April 1, 1999 . An attempt to actually implement the RFC , which was intended as an April Fool's joke, took place on April 28, 2001 in Norway. Nine packages were sent over a distance of five kilometers. Each of these packets was transported by a pigeon within two hours and represented data transmission in the form of a ping . However, five of the nine responses were lost on the way, which corresponds to a loss of approx. 56%.
With RFC 6214 (April 1, 2011) the IPoAC standard was expanded to be IPv6- compatible.
description
Advantages and disadvantages are listed in the specification of the method. The experimental standard supposedly promises high latency with low throughput . Because of the 3-D routing capabilities of the carrier pigeon, any number of packets could be traveling at the same time, which, in contrast to conventional network lines, do not significantly influence each other. Another advantage over common methods such as packet radio is that the range is practically not influenced by the topography. Since the Internet protocol can compensate for packet losses on its own, the loss of a packet is bearable. Not to be neglected is that the pigeons can attack worms and other vermin on their own and also reproduce themselves. The disadvantage is that only point-to-point connections between two precisely predetermined locations are possible.

The transfer carried out by the UNIX user group in Bergen resulted in the following characteristics for the ICMP layer:

In September 2009, a South African company criticized Telkom's slow broadband connections by using a carrier pigeon to transfer data . This transported 4 gigabytes over 96.5 kilometers. The flight and the data transfer from the USB stick to the local network took two hours - during this time the ADSL connection handled just four percent of the data.
