Status of This Memo โจ
okay so this memo describes an experimental method for wrapping IP datagrams up in avian carriers ๐ฆ (birds, bestie). it's mainly useful in Metropolitan Area Networks ๐๏ธ. it's an experiment, NOT a recommended standard, so don't treat it like one ๐ . distribution of this memo is unlimited ๐ซถ.
Overview and Rational ๐๏ธ
ngl, avian carriers are giving high delay, low throughput, and low altitude service ๐. the connection topology is limited to a single point-to-point path for each carrier, used with standard carriers ๐ฆ. but you can run lots of carriers without much interference between them, except in early spring ๐ธ. that's because they get 3D ether space to fly around in, unlike the 1D ether IEEE802.3 is stuck with ๐ค. the carriers also have an intrinsic collision avoidance system, which boosts availability ๐.
unlike some network technologies, like packet radio, you're not limited to line-of-sight distance ๐ง. and connection oriented service is available in some cities, usually based on a central hub topology ๐.
Frame Format ๐
the IP datagram gets printed on a small scroll of paper in hexadecimal ๐. each octet is separated by whitestuff and blackstuff ๐ค๐ค. the scroll is wrapped around one leg of the avian carrier ๐ฆต. then a band of duct tape holds the datagram's edges down ๐ฉน. the bandwidth is limited to the leg length, so it is what it is ๐ . the MTU is variable, and paradoxically, it generally goes UP as the carrier gets older ๐. a typical MTU is 256 milligrams โ๏ธ. some datagram padding may be needed โจ.
upon receipt, the duct tape comes off ๐ญ, and the paper copy of the datagram gets optically scanned into an electronically transmittable form ๐.
Discussion ๐งโโ๏ธ
multiple types of service can be provided with a prioritized pecking order ๐. there's also built-in worm detection and eradication, which is honestly iconic ๐ฅ. because IP only guarantees best effort delivery, losing a carrier can be tolerated ๐ซ . over time, the carriers are self-regenerating ๐ฑ. broadcasting is not specified, and storms can cause data loss โ๏ธ. there is persistent delivery retry, until the carrier drops ๐ฆ. audit trails are automatically generated, and you can often find them on logs and cable trays ๐.
Security Considerations ๐
security is not generally a problem in normal operation ๐, but special measures must be taken (such as data encryption) when avian carriers are used in a tactical environment ๐จ. no cap, don't skip this part ๐ญ.
