Thus spake <alex@yuriev.com>
What it means is that you don't have enough capacity so you drop packets on the floor of those who pay you less money before dropping on the floor packets of those who pay you more. At the end, you still drop packets." Having capacity *always* makes a network better.
Ah, but there are times when suboptimal paths have spare capacity but you are dropping packets on the optimal path(s) due to congestion. An "unselfish" routing model would allow you to use _all_ available capacity in the network before packets get dropped. This isn't just theory; the ISPs using an "unselfish routing" schemes today consider that a competitive advantage and thus don't publish details.
