The right to prioritize traffic isn't a right that they should have. Selling higher priority across the backbone to the highest bidder leaves everyone else to fend for themselves on what's left. It causes a false scarcity that will drive cost. Bandwidth will become commodity and cost will be influenced much the same way other commodities are. I don't care what a provider does within their network. Its their business. But that is where that influence should end, at the provider edge. Do all the custom queueing you want to that point, but let the traffic go thru the backbone like it always has.
Its like getting on a city bus and expecting that you will have the same seat and never having any one sitting around you. Its public transport. If a company wants a private network, with priority built in end-to-end they can build one that way. I have worked with many corporations that do just that. But don't use the public city bus system if you are expecting a limousine ride. It just doesn't work that way, and it shouldn't. I have worked with companies whose yearly budgets for circuits are in the millions of dollars a year, so they can secure their network end to end. That is the cost of doing business. Yeah, they could do it cheaper with vpn tunnels thru the internet, but they are subject to slowdowns just like everybody else. They understand of you take the public bus, you share. You don't want to share, get yourself a limousine.
