Where's your evidence. You have none because you are making a claim that is demonstrably false.
So you're under the delusion that what you do at home is exactly the same as what a Telecom provider does, just bigger? You're not even playing in reality with your comments at the moment.
Really? How have I NEVER run into that fact in the twenty years I've spent building and protecting the Internet? We never discussed it in my Bachelors program, Masters program, any of the dozen certifications I have, any of the publications I've been in... WOW, you REALLY blew my mind... If you are going to talk down to people demonstrating how little you know on the subject, make you have supporting evidence.
Ya think?
Then why do ISPs/Telecom providers spend millions (tens of millions) of dollars doing that? Why do they buy $100,000 routers that have that capability? Why do I spend my time working with architects solving problems related to using QoS, CoS, VoIP traffic. You are out of your depth and have NO idea what you are talking about. You STILL haven't provided evidence to support your claims. Stop, you don't know what you are talking about.
Let's continue your example. Assume two vehicles approach the bottleneck at the same time. One is a Sunday driver just tooling around neighborhoods. The other is the Ambulance you are in having a heart attack. Who do you want to go through the bottle neck first? The Sunday driver on his way to nowhere in particular, or you?
THAT IS QUALITY OF SERVICE. The higher priority gets through. WHY is it higher priority? Because it has a schedule to keep. It's more important because if the packet containing audio doesn't get through in time, it's worthless (or dead). GET IT NOW. Just because two different passengers travels by car, that does NOT mean that the passengers have the same value.
And I'd like to point out your argument has contradicted your argument. Earlier you said we were only using 1% of capacity, now you say we are nearing capacity. You just lost this argument.
And now you change your argument back. No, I'm sorry, you don't get to flip flop (you're spouting nonsense with no evidence, so I guess it doesn't really matter).
You obviously don't understand that it costs LOTS of money to increase the amount of hardware that the network uses. So providers use MPLS, VoIP, VPLS, Metro Ethernet.... Tech you obviously have no understanding of. Yes, there's fiber too... So what. Why shouldn't an ISP use all technology at their disposal to maximize the value of their network? Shareholders don't like it when you spend money on hardware unnecessarily.

You are the one making absurd claims. YOU are the one required to provide evidence, something you have failed to do. No, you don't get to shift the burden of proof. At this point I have no doubt you are WAY out of your depth. This has been fun. Come back with something to support your claims.
