There are two basic components to network OS, the control plane and the
data plane.  VyOs has the old V1 which is filesystem based control plane
and kernel dataplane. DaNoS has yang/netconf database based control plane
(in Go) and DPDK (or switch offload?) based dataplane.  Ubiquity redid
the control plane as well, and uses their own hardware for dataplane.

So more of "my grandfather's ax"...
