We differ ;-). I don't think we can add anything to our arguments,
so I'd like to know what other people think - one level
vs several levels.
Since you ask: what I would like to see is a combination of something
from the LISP family combined with a hierarchical mechanism like CRIO
that allows packets for which there is no mapping yet to be delivered
through increased stretch.
The number of levels in the hiearchy would presumably be greater than
one, but this is something that the operators should figure out.
I'm not sure I've digested all the elements of your IFSD (idea for
shooting down) approach, but in general, I'm suspicious of an approach
where there is emphasis on having different levels of an hierarchy
that isn't a natural extension of the addressing hierarchy because
this requires extra effort to find out where in the hierarchy a
certain prefix is present at any given time. An approach where the
routing hierarchy is aligned with the address bits seems a more
natural choice to me. But I'm open to hearing more arguments.
