i get the impression that routers are hard to configure well, particularly used in "complex" ways. isn't there some hardware startup looking at fixing this? i can't remember the name, but thought i had read about it here before.

naivley, it seems like the configuration is at too low a level - individual routers - and that there should be higher level coordination with support for simulating different conditions. or does that already exist? what's state of the art for places like google to manage routers?
