More like, ipv4 is going explode the routing table in the next 5 years? On a percentage basis v6 is in fact growing faster. but one of these things is growing at 1k-2kprefixes a week and the other is ~ 2k prefixes total. It's plausible that you need 500k v4 dfz routes at or before 2012 that would be right on schedule from the 250k mark... Fitting a curve to the v6 table growth is an interesting experiment in modeling your expectations. I think it's an excellent opportunity for a synthetic futures market. > The > manufacturers still seem to think low traffic routers don't need much > memory or CPU. > What projections are you using regarding the default free zone over the > next 5 years when picking new hardware?
