Reading RFCs for Fun
Posted on 2015/01/16 by shanmoon
Whenever I am having a bad day, I like to read RFC 1149 – A Standard for the Transmission of IP Datagrams on Avian Carriers which describes how “Avian carriers can provide high delay, low throughput, and low altitude service.” It contains gems like “Multiple types of service can be provided with a prioritized pecking order” and “An additional property is built-in worm detection and eradication.”
This RFC was actually implemented and tested by the Burgen Linux Group (read more here), although the ping log seen below does indeed show it is a high delay implementation. If you are technically inclined, read it here for a good laugh and the implmentation details here.
