基于鸟类载体的网际协议

RFC1149, 2549, 6214

基于鸟类载体的网际协议(A Standard for the Transmission of IP Datagrams on Avian Carriers)，其QoS(IP over Avian Carriers with Quality of Service)，其IPv6适配(Adaptation of RFC 1149 for IPv6)，ietf官方网站一本正经有发布。
🕊

The IP datagram is printed, on a small scroll of paper, in
hexadecimal, with each octet separated by whitestuff and blackstuff.
The scroll of paper is wrapped around one leg of the avian carrier.
A band of duct tape is used to secure the datagram’s edges. The
bandwidth is limited to the leg length. The MTU is variable, and
paradoxically, generally increases with increased carrier age. A
typical MTU is 256 milligrams. Some datagram padding may be needed.

Upon receipt, the duct tape is removed and the paper copy of the
datagram is optically scanned into a electronically transmittable
form.

—from RFC1149

RFC1149提到：所传输的数据打印在纸上，然后绑在鸟（比如鸽子）腿上，带宽受限于鸟腿长度。MTU大致和鸟的岁数成正相关。

RFC1149发布于１９９９年，那时候还没有小Ｕ盘。若搁现在，把Ｕ盘绑在鸽子腿上进行数据传输，带宽即增加Ｎ个数量级。

当然， RFC1149发布日期是4月1日😁，其他两个标准也是4月1日发布的。
