Explain like I’m five: What is a SDN (Software Defined Networking)

Imagine you have a toy train set. Normally, you’d manually arrange the tracks, decide where the train goes, and adjust any obstacles. It’s a bit cumbersome, right?

Now, imagine if you had a magical remote control that could instantly change the layout of the tracks, direct the train anywhere, and move obstacles with a simple push of a button. This remote control gives you a much easier and flexible way to manage the train set.

In the world of computer networks, SDN (Software Defined Networking) is like that magical remote control. Instead of manually setting up and managing network devices (like routers and switches) one by one, SDN lets you control and adjust the entire network using software. This makes managing networks more flexible and efficient.
