Network neutrality (also net neutrality, Internet neutrality) is a principle proposed for residential broadband networks and potentially for all networks. A neutral broadband network is one that is free of 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 one where communication is not unreasonably degraded by other communication streams.
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 that given rate of access.
Though the term did not enter popular use until several years later, since the early 2000s advocates of net neutrality and associated rules have raised concerns about the ability of broadband providers to use their last mile infrastructure to block Internet applications and content (e.g. websites, services, protocols); particularly those of competitors. In the US particularly, but elsewhere as well, the possibility of regulations designed to mandate the neutrality of the Internet has been subject to fierce debate.
Neutrality proponents claim that telecom companies seek to impose a tiered service model for the purpose of profiting from their control of the pipeline to remove competition, create artificial scarcity, and buy their otherwise uncompetitive services. Many believe net neutrality to be primarily important as a preservation of current freedoms. Vinton Cerf, co-inventor of the Internet Protocol, Tim Berners-Lee, father of the web, and many others have spoken out strongly in favor of network neutrality.
Opponents of net neutrality include large hardware companies and members of the cable and telecommunications industries. Critics characterised net neutrality regulation 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 have intentionally slowed peer-to-peer (P2P) communications. Others have done exactly the opposite of what Telecom spokespersons claim 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 anti-competitive tying ("bundling").
Critics also argue that data discrimination of some kinds, particularly to guarantee quality of service, is not problematic, but highly desirable. Bob Kahn, Internet Protocol's co-inventor, has called "net neutrality" a slogan, and states that he opposes establishing it, warning that "nothing interesting can happen inside the net" if it passes: "If the goal is to encourage people to build new capabilities, then the party that takes the lead in building that new capability, is probably only going to have it on their net to start with and it is probably not going to be on anybody else's net."
However, he also said "by virtue of doing that, you tend to fragment the net. And anything that will tend to fragment the net I'm opposed to, provided it's not an incremental evolution of a new technology that's happening."
