While I'm making a bit of an assumption, if we can't support that rate, how would we ever get to 5M in 20 years? > Actually, quite a few people are worried that a 5M prefix Internet is > a possibility.

I have no worry. 1 order of magnitude growth in 20 years is way below the rate computing power and bandwidth are increasing. Heck, I think a 50 million entry table in 20 years is well within the advances in hardware we will see in that time. > Glad to see you are thinking of an lifespan of more than just a few > years. Indeed, I think many are thinking of even longer time frames. Which is excellent. I think a 50-100 year planning window may be pushing the limits of what we can achieve, but I'm all for trying! -- Leo Bicknell - bicknell at ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request at tmbg.org, www.tmbg.org -------------- next part -------------- A non-text attachment was scrubbed...
