ryu controller, use the command:  `ryu-manager --observe-links custom_controller.py`  \nto run the mininet script, use the command:      `sudo python3 mininet_topo_script.py`  \n\nor you can as well create a mininet topology from the terminal eg: `sudo mn --topo single,3 --mac --controller remote --switch ovsk`  \n\nMake sure to start the ryu controller first.  \nSo that way the controller can detect network devices and their links as they are instantiated   \non the mininet network (^_^
