==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?
