I doubt we want to move away from those concepts.
I think we all do - except technology is not there yet. Just imagine if over a single piece of fiber you will get infinite bandwidth delivered over unlimited modulation frequency spectrum ... IMHO till real true optical switching is a commodity we are stuck with statistical multiplexing. But optimistically I think time will come when you will be able to setup end to end optical paths in true any to any fashion with real end to end resource guarantees. Then next generations will be looking at current routers like we look today at strowger telephone switches :) Cheers, R. PS. All of the current attempts to turn IP statistical multiplexing into network slicing or deterministic networks are far from scale or practical deployments (IMO).

I doubt we want to move away from those concepts. We rely on many services today delivered over the public Internet that virtualize and still perform. Even good ol' video streaming, which was predicted to break the Internet. So not sure what applications are driving the demand for "greater QoS" on 5G networks, in real terms. Mark.
