This book describes the TCP/IP protocol suite, but from a different perspective than other texts on TCP/IP Instead of just describing the protocols and what they do, we'll use a popular diagnoshc tool to watch the protocols in action. Seeing how the protocols operate in varying circumstances provides a greater understanding of how they work and why certain design decisions were made. It also provides a look into the implementation of the protocols, without having to wade through thousands of lines of source code.

ARP应答是直接送到请求端主机的，而是广播的。

The ARP reply is thus sent directly to the requesting host; it is not ordinarilly broadcast (see Section 4.8 for some cases where this rule is altered).

internet这个词第一个字母是否大写决定了它具有不同的含义。internet意思是用一个共同的协议族把多个网络连接在一起。而Internet指的是世界范围内通过TCP/IP互相通信的所有主机集合(超过1 0 0 万台)。 Internet是一个internet,但internet不等 于Internet。

IP has a simple error handling algorithm: throw away the

datagram and try to send an ICMP message back to the source.

以太网数据帧的物理特性是其长度必须在4 6～1 5 0 0字节之间，而数据帧在进入每一层协议栈的时候均会做一些封装。

当目的主机收到一个以太网帧时，就在协议栈中从底向上升，同时去掉各层协议加上的报文首部。每层协议盒都要去检查报文首部的协议标识，以确定接收数据的上层协议。这个过程称作分用。
