IP over Avian Carriers or RFC 1149 is a humorous Request for Comments document issued by the Internet Engineering Task Force. It describes how Internet Protocol traffic may be carried by homing pigeons. It was written by D. Waitzman and released on April Fool's Day 1990, one of the April 1st RFCs.
RFC 1149 was actually implemented by the Bergen Linux User Group.
Waitzman described an improvement of his protocol in RFC 2549, IP over Avian Carriers with Quality of Service, (April 1, 1999).
