often what seems to happen is what we call "curve ball routing,"
though i am sure you cricket players have a different term.
new routing propagates in sort of a wave front. packets proceed
from source on old routing information until they reach a router to
which new information has propagated, and then they proceed on new
we have empirical reason to suspect that a packet can pass through
more than two (old and new) routing information states enroute to a
and credit should also go to tim, morley, jun, and a couple of
