want to send some packets to pox controller connected with mininet

Question

我是 pox 控制器的新手，想编写一个代码，其中交换机将向控制器发送一些数据包，而控制器将向交换机发送 hello 数据包

Answer 1

If you want TCP packets with mininet you can use Python to setup a simple HTTP server and perform a wget like opening the page hosted there

Assuming you start mininet with

sudo mn --controller remote

Then you have 2 hosts h1, h2. Use h1 to run a simple http server and h2 to read the site from that server

mininet> h1 python -m SimpleHTTPServer 80 &
mininet> h2 wget -O - h1
