Much of the advocacy of legislatively-mandated network neutrality is based on a simple fallacy - namely, that differing charges to suppliers of content to the Internet for correspondingly differing speeds of delivery are inherently discriminatory. They are not; and an attempt to prohibit them would prevent the Internet's offering a full range of services, with widely diverging tolerances for latency. Preservation of the open end-to-end character of the Internet may well, however, require vigilant prohibition of vertical squeezes and other unfair methods of competition and authority of an antitrust agency to compel interconnections.
