Mbone

Okay kiddo, imagine you want to have a video call with your friend who lives far away. But you not only want to see your friend's face, you also want to see what's going on around them. Like if they have a pet you can say hi to or if they're sitting in a cool park.

Now, imagine many people want to do that at the same time, like a whole class of kids want to have a virtual field trip to the zoo. It would be difficult to handle all the video streams separately, wouldn't it?

That's where the mbone comes in. MBone stands for "Multicast Backbone". It's like a big network street that allows many video streams to travel at the same time, so your video can join others and all go to the same destination in a more organized way. Think of it like a big bus that carries many kids together to the zoo.

Using mbone means you don't have to send the same video stream multiple times to each person who wants to see it, which saves time and resources. It also makes it easier to join or leave the video call, like getting on and off a bus.

So, in a nutshell, mbone is a special way of sending video and audio over the internet that allows many people to share the same stream and join or leave easily. It's like a virtual bus that makes group video calls smoother and more manageable.
