So let me put this another way: I agree with Sean's original comment that adding more bandwidth makes networks better, but only on condition that you know how to use it.
Someone who built a rather good network used to say something along the lines of "You are confused. QoS does not stand for Quality of Service. It stands for Quantity of Service. 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.
Yes but... I seem to recall a few things about the network you are referring to (the "You are confused" is kindof a tip-off :P), and one of those things was the complete and total meltdown with every fiber cut. Sometimes you can win the battle with quantity of service, and sometimes you just don't have a choice in the matter... Why throw away the ability to keep your network alive in the event of fiber cuts, DoS, or just the realities of business, because of engineering religion... -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
