Net neutrality is a principle proposed for user access networks participating in the Internet that advocates no restrictions on content, sites, or platforms, on the kinds of equipment that may be attached, and on the modes of communication allowed, as well as communication that is not unreasonably degraded by other traffic.
The principle states that if a given user pays for a certain level of Internet access, and another user pays for a given level of access, that the two users should be able to connect to each other at the subscribed level of access.
Neutrality proponents claim that telecom companies seek to impose a tiered service model in order to control the pipeline and thereby remove competition, create artificial scarcity, and oblige subscribers to buy their otherwise uncompetitive services. Many believe net neutrality to be primarily important as a preservation of current freedoms. Vinton Cerf, considered as a "father of the Internet" and co-inventor of the Internet Protocol, Tim Berners-Lee, creator of the web, and many others have spoken out in favor of network neutrality.
Opponents of net neutrality characterize its regulations as "a solution in search of a problem", arguing that broadband service providers have no plans to block content or degrade network performance. In spite of this claim, certain Internet service providers (such as Comcast) have intentionally slowed peer-to-peer (P2P) communications. Still, other companies have acted in contrast to these assertions of hands-off behavior and have begun to use deep packet inspection to discriminate against P2P, FTP and online games, instituting a cell-phone style billing system of overages, free-to-telecom "value added" services, and bundling. Critics of net neutrality also argue that data discrimination of some kinds, particularly to guarantee quality of service, is not problematic, but is actually highly desirable. Bob Kahn has called the term net neutrality a "slogan" and states that he opposes establishing it.
