NetSim doesn't implement a topology discovery protocol for SDN.
Instead in SDN, the following configurations are done to set the controller device and in the client devices that are to be controlled:
- In the device to be configured as an SDN controller, the SDN_Controller option is set to true
- In the client devices to be controlled by the device configured as the controller,
- SDN_Controller option is set to false
- SDN_Controller_DeviceName option is set to the name of the device that is configured as the controller (For Eg: Wired_Node_3)
So after configuring the above settings, the controller is able to have the complete picture of the whole network that comes under its control, even if it is not directly connected to all the devices in the network.
