Most comemrcial routers HAVE been switches for the last 20 years. The
first packet to come through would be routed by the cpu, but the result
of that routing table look up would be sent to an interface cache and
all the packets for the same destination after that would be switched
directly by the interface hardware, leaving the CPU alone.
I think that what they meant by this is that the routers nowadays have
to do policy routing and load-balancing, that is inspect up to the
application layer before deciding where to send the packets, rather than
just based on the destination address.
