Simple question. Where is "fair dropping" that different from "fair 

I'm with you that we try to obviate the need of some reasonable resource 
management in the Internet. However: When you require some "fair 
dropping" mechanism, you could simply use the same implementation and 
instead of scheduling n flows in a round robin manner like this: "Each 
turn, one flow is served and n-1 packets are dropped" frame as "Each 
turn, one flow is served and the other n-1 flows wait." And then you 
have the fair queueing approach which already well exists. And which you 
reject because it would be too expensive.
