Why Leaf Spine design architecture chosen for next generation data centers ? Why three tier design architecture is not being used for data centers ? What was the limitation of old design which restricts it to be used for data centers ?

What is the different between leaf switches and spine switches ?

I saw these two terms while reading 5G core network related material. Can someone please explain the difference between these two terms ? I also want to know due to position of these switches in data center there names are different or actually they are different kinds of hardware switches and different type of functions are performed by these two ?

Difference between running OVS (Open vSwitch) in user space and kernel space ?

Open V Switch is a soft switch and it can work same as normal switch or even more things it can do compare to normal switch.

I want to know can I run the same switches in kernel mode also and if yes it is possible then how I can and what could be the reason for doing so ?
