Computer network top-down method [Experiment 1]

Experiments Overview

Software installation package wireshark .

在以前，包分析软件非常昂贵，wireshark的出现改变了这一局面，让我不禁再一次高呼开源万岁！

Once downloaded, the document reference experiment, step by step, a very simple experiment, similar to the book Preface, let us know wireshark software, and use it to view an HTTP GET request.

后续的实验会介绍套接字编程以及各种网络协议

Some experiments of a quiz:

1. List 3 different protocols that appear in the protocol column in the unfiltered
   packet-listing window in step 7 above.

答：TCP、HTTP、DNS、UDP、ARP ...... and so on

2. How long did it take from when the HTTP GET message was sent until the HTTP
   OK reply was received?

A: As shown, about 0.29s.
