Per-flow state has > been shown to scale poorly in Internet backbones. I agree with you that it doesn't scale well to huge routers. I am certain that it would work very badly in MCI's backbone. It probably will work just fine in a small provider, though, and those are most of the guys who want to roll their own out of PCs anyway. If you want to pump half a gigabit through on a giant peering router, caches will lose, and the only thing that will do you right is real router hardware. Perry
