Umm, can we please be careful and distinguish between 'routing', in the sense
of 'path selection', i.e. the (distributed, in the current architecture)
computations which select source->destination paths; and 'forwarding', the
process (necessarily in a single switch) of getting a packet in, selecting
its next hop (based on the output of the path selection), and sending it
out?
I know 'routing' is somewhat ambiguous, because one would think it's what
'routers' do - which also includes 'forwarding' - which is why I use the
term 'path selection' or 'path computation' a lot, to make it explicit
that it's that kind of 'routing' I am thinking of.
I reallly don't care what terminology gets used, as long as i) it is precise,
and ii) people agree on it. So if people want to use some other, less
ambiguous term, for what I have called 'path selection', that would be fine
with me.

PS: The 'routing' in RRG is of course the 'path selection' meaning.
