Leo - Draw two curves, the first y=x/2, the second y=x^2 Move the value of x for y=1 for the first curve left by 2, 5 or 10 and it will still be surpassed by the second curve. You will even see this for a second curve of y=x*2 or y=x. The global routing table size HAS grown exponentially in the past. Rationalize it any way you want, blame whatever you like, but there is no known way to construct a router that can handle that kind of growth in anything but a short term, and the trend for the components in the router growth curve is simply not going to increase to a long term superlinear rate. A 10x system performance boost today just moves the x point for y=1 of fundamental curve claimed by Moore's Law to the left a few notches. Or are you claiming that routing equipment will have a fundamentally different, and larger, growth curve than other computing systems? (I think there is a basis for claiming that there are some reasons which would support a _shallower_ growth curve for routing equipment, actually). In short: are you claiming that the caeteris paribus assumption in comparing Moore's Law to global routing table size is clearly false? It would be nice to see even a partial proof of such a claim.
