  • Method 1 is the classical method to deploy a custom topology in Mininet. You can specify in the same command the controller, like this :

    sudo mn --custom ~/mininet/custom/filename.py --topo mytopo --controller=remote,ip=[CONTROLLER_IP],port=6633

    or if you don't, Mininet will use the default.

  • Method 2 executes the [FILENAME] file. Note that here you have to specify the controller which you will use inside the python script. This is the difference with Method 1.

  • Method 3 makes the [FILENAME] file executable with the first command, and then executes it. It is the same as Method 2.
