I can't tell if you're being sarcastic or not. Cisco routers, at least at the level I've been exposed to, don't have particularly good switching times. In point of fact, switching an IP header through a few-hundred-thousand-entry routing table is something that any desktop CPU can do in a microsecond or so. Companies like Cisco have managed to convince a lot of people that routers are these hugely complicated devices. They aren't.

The hardware side of long haul fiber networking is where the voodoo is. Routing? Not so much.
