| "From now on, we should make this a primary distinction between switch | and a router: If a device has vertical line cards, it is a router, if | horizontal, it is a switch, unless there are two or more vertical slots | within any horizontal slot plane, then it is, in fact, a router." | | How does that sound?

Like the start of some new RFC :-)

which way is up? perhaps you had better state the problem in terms of X,Y,Z coordinates at a minium. Adding the fourth vector, time, may be useful as well; e.g. "... it was a router last night..."

maybe polar coordinates are better situated for distance vector protocols?
