I guess people are still spectacularly missing the real point. The point isn't that the latest generation hardware cpu du jour you can pick up from the local hardware store is doubling processing power every n months. The point is that getting them qualified, tested, verified, and then deployed is a non trivial task. We need to be substantially behind moores observation to be economically viable. I have some small number of route processors in my network and it is a major hassle to get even those few upgraded. In other words, if you have a network that you can upgrade the RPs on every 18 months, let me know. /vijay John Paul Morrison, CCIE 8191 > > A better comparison would be with a Playstation or Nintendo, > > Leo Bicknell wrote: > > In a message written on Thu, Aug 09, 2007 at 04:21:37PM +0000, [EMAIL > PROTECTED] wrote: > > (1) there are technology factors we can't predict, e.g., > moore's law effects on hardware development > > Some of that is predictable though.
