g.709

Okay kiddo, so g.709 is like a set of rules that helps people who control big networks of communication to make sure that everything is running smoothly. It's almost like a referee for the network to make sure that all the players are following the same set of rules.

When we talk about big networks of communication, we mean things like the internet or phone lines that connect people all over the world. All these networks have lots of different data and information that needs to be sent back and forth between different places. And when lots of different things are happening all at once, things can get pretty complicated.

So, to keep everything running smoothly, g.709 helps to organize all the information that needs to be sent and received across the network. It does this by assigning different colors or wavelengths to different types of data, kind of like how you might put your toys in different bins for different types of toys.

This way, everyone on the network can keep track of what data is being sent and where it needs to go, making sure everything is running efficiently and without any problems.

Overall, g.709 is just one way we can make sure that all the communication happening on big networks is organized, easy to follow, and working correctly.
