The issue isn't in storing hundreds of thousands, millions, or tens of millions of routes. This is, all things considered, a piece of cake. The issue is getting the route out of storage, for each packet coming through the router, at a rate of millions of packets per second for each core router. Each IP core router is doing about the same lookup work as the whole combined PSTN network is for all of its freely routed numbers. It is, or should be, quite viable... but not easy, as we've all found. -george william herbert [email protected] |
