What is Network function virtualization (NFV)?

Network function virtualization (NFV) is like having a toy box that can change its contents whenever you want, no need to buy new toys every time.

Imagine your favorite toy box is in the middle of your room. Normally, if you want to play with a robot, you have to take out the robot and put away whatever was there before. But with NFV, it's like having a magic remote control that lets you instantly switch between different toys, or network functions, without touching anything.

Network functions are like special helpers in a computer network. They help data travel from one place to another, just like how your toy box helps you play different games. In the old days, these helpers had to be physical machines, like big robots that couldn’t move or change. But with NFV, these helpers can live inside a regular computer, and you can turn them on and off like switching between toys.

This means networks can be more flexible and easier to manage, just like how your toy box makes it fun to play all day long!
