Is that really that significant a problem? Moore's Law should have dealt with memory and processing power issues severalfold in the time since IPv6 rollout was called for.
It strikes me that it's more likely a lack of strategic investment in infrastructure.
- jauer 13y agoGenerally speaking even now you can't do route lookups fast enough to handle provider traffic volume with current general-purpose CPUs (although it seems to be on the edge of possible). Instead routes are loaded into special ASICs (TCAM: http://en.wikipedia.org/wiki/Content-addressable_memory http://en.wikipedia.org/wiki/Content-addressable_memory) that seem to not follow Moore's Law, be it due to low volume or other limitations (perhaps not technical). Routers using TCAM seem to max out between 1-2M routes (divided across v4, v6, MPLS, etc). More recent routers are using slightly more flexible processors so there's some hope but the router product cycle is fairly lethargic.
