What do you call Arista? Also there is a lot of interesting "virtual appliance" networking going on.

I agree the right choice today is almost certainly a C or J router and probably C or A switches, but e.g. hardware load balancers like F5 seem to be losing out to software in most deployments (increasingly).

I built a decent sized network with Zebra 15y ago, which was pretty obviously the wrong tech, but interesting.
