IT人一般都知道RFC一般是很牛的文档，因特网的很多基础协议是基于各个RFC的.不过偶然一个机会，偶

发现了RFC1149(http://tools.ietf.org/html/rfc1149)，居然是90年提出来的，现在看起来，很有趣.

这个RFC目标主要是怎么解决"Transmission of IP Datagrams on Avian Carriers"，就是利用鸟类(如信

鸽)作为IP包载体，建立点对点的IP通讯，哈。基本方法如下：

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 arrier 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.

也就是说，把IP包数据以16进制的方式打印在一小卷纸上，然后绑在鸟类(信鸽)腿上，让鸟类传输IP包，

这样在两端建立起一个IP通讯通道.另外文档指出：“带宽取决于鸟类(信鸽)腿的长度”.
