How Does CN 25 : TCP Congestion Control with Example Work?

TCP Congestion Control is like when kids on a slide learn to share so everyone can go down smoothly.

Imagine you're playing a game where you send toy cars down a track from one end of the room to the other. Each time a car reaches the end, it sends back a signal saying "I made it!" This helps you know how many cars you can keep sending without them all getting stuck in traffic (or crashing into each other).

Congestion control is like figuring out how many toy cars you should send at once so the track doesn’t get too crowded. If you send too many, they’ll slow down or stop, just like when too many cars on a road cause traffic jams.

There are different ways to do this, and one common way is called Additive Increase / Multiplicative Decrease (AIMD). It’s like if you start by sending one more car every time the track is clear, but if things get backed up, you send fewer cars all at once, it's a balance between patience and speed.

So, TCP Congestion Control helps keep the flow smooth, just like how kids on a slide learn to take turns so everyone can have fun!
