Nonblocking minimal spanning switch

Okay kiddo, have you ever played with a bunch of train tracks and toy trains? Imagine you have a lot of tracks and you want to make sure that each train can go from one end of the track to another without crashing into each other. That's what we call a "switch" in computer networking.

Now imagine you have a LOT of toy trains and tracks, and you need to find the shortest path for each train to get from one end of the track to another. That's what we call a "minimal spanning switch" in computer networking.

But sometimes, some of your trains might get stuck or have to wait for other trains to pass through. That's what we call a "blocking switch." However, with a "nonblocking" switch, all of your trains can travel through the tracks at the same time without getting stuck or causing accidents.

So basically, a nonblocking minimal spanning switch helps a lot of data or information travel through a network at the shortest possible route without getting stuck or causing problems. It's like having a lot of toy trains travel through a lot of train tracks without getting stuck or crashing into each other.
