项目需要使用到了 dummynet，一般是用来控制流量，带宽，延迟，丢包率什么的，废话不说，直接进入安装流程
1.下载dummynet 的源代码（source code）
http://info.iet.unipi.it/~luigi/dummynet/#3d2a
点选左边Availability,点选source code 下载
2.下载完解压缩，在readme里其实有完整的安装指南，在这里我复制过来并翻译一下
注意，这是直接使用已经build好的exe文件，如果要自己build代码，可以参看readme下面的build
Windows:
A pre-built version is in binary/ and binary64/ directories. 32位和64位都是适用的
INSTALL THE NDIS DRIVER
- open the configuration panel for the network card in use 控制面板，打开网络和共享中心
(right click on the icon on the SYSTRAY, or go to
Control Panel -> Network and select one card) 在你正在使用的网卡上点右键-》属性-》安装-》服务-》添加
- click on Properties->Install->Service->Add
- click on ‘Driver Disk‘ and select ‘netipfw.inf‘ in this folder 打开你下载的source code的目录解压，打开binary文件夹，添加netipfw.inf，然后会要你选ipfw
- select ‘ipfw+dummynet‘ which is the only service you should see .sys,也在这个binary目录下，然后确定就OK
- click accept on the warnings for the installation of an unsigned
driver (roughly twice per existing network card)
Now you are ready to use the emulator. To configure it, open a ‘cmd‘ 最后你可以在cmd下测试ipfw.exe或者用test.bat测试
window (REMEMBER to run it as Administrator)
and you can use the ipfw command from the command line.
Otherwise click on the ‘TESTME.bat‘ which is a batch program that
runs various tests.
