Sure. And the point I was trying to make is that it's better to reserve 
bandwidth than skipping a frame, but IP doesn't support that.

Yep. And I'm saying that the primary reason people don't use TCP is to 
compensate for a lack of things like bandwidth allocation and routing 
assurance. Nobody used TP4 over a network that will work fine with TP0.
