A simple explanation As a simple explanation contrasting Network Neutrality NN and quality of service QOS I suggest we use a highway analogy Network neutrality is like a highway with multiple lanes all being used equally anytime and at the same high speed limit Quality of service is like a highway where each car requires a special license plate i e cost to drive in the fast or slow lane Each have their advantages and disadvantages NN can have traffic jams if everyone uses the highway simultaneously thus ruining just in time deliveries but when traffic flows everyone travels at the maximum speed QOS can insure just in time deliveries by creating a clear fast lane but others are relegated to crowded lanes with slower speed limits Since the fast lane is more expensive large use commercial and the wealthy will find travel easier and worth the price while the small use drivers and the cost conscious will have longer commutes The NN highway designers say forget all those licenses regulations and special lanes let s ramp up the speed limit add more lanes and stick more people in each car until the traffic jams go away Everybody will have the same commute time The QOS highway designers say why spend all that money on unneeded road improvements when the highways are empty except for the occasional traffic jam that a little regulation and traffic signs can eliminate It reduces to do you want a toll road or a freeway
