Innovation, Regulation, and The Internet: "The network is designed not to know these differences, but simply to take the packet offered and route it as it is addressed. This doesn't mean that users can't discriminate. The point of end-to-end is not that everything goes; it is to locate the power to discriminate in the users--they choose--and to remove that power from the network. The principle thus regulates the power to discriminate. It requires that the network have none."
