I fully agree with that angle and the sentiments expressed in rfc4984.
However, although of course I'm not a router vendor, if big data (tm) and
scalability is a problem that can be solved on other planes we should be
able to attack the routing problems as well. Maybe the current solutions
don't fit the problems anymore. It would probably mean departing from the
current router architectures and looking at much more parallel modular
architectures all highly parallel and using where possible a lot of
off-the-shelf components, e.g. where one engine does the control plane
work and only does updating, policing, flow tagging/labeling and a data
plane engine only forwards traffic. Of course this is hugely over
simplified, we're getting very close to OT here as it is already :-)
(don't forget in the high volume hardware market we've reached some kind
of limit on speed as well, it'll be more about parallel processing now &
next)

> I tell you, widespread PI adoption is poison for the network.
Maybe, maybe not. If I read things correctly, the suggestion is to take
the business side of things into account as well. It's kind of curious
that this should stop at the (core) infrastructure side. The businesses
and people that are actually using the Internet are equally if not more
important. Since 2007 a lot of things have changed once again or maybe
evolved further; people and businesses have grown even more dependant on
Internet connectivity as could only have been expected. PI is a necessity
for a lot of businesses, large _and_ small(er). I get a feeling the whole
discussion is still only a technical one as itpasses by the actual
Internet users (companies). If there is an element of the business, most
of the people involved only argue on behalf of the (big) ISP side.
