What is Net Neutrality?

Net neutrality is also called network neutrality. In general, it is defined as a network design principle. It means that people can access to network equally, and the principle prohibits providers from offering discriminatory the Internet provision. For example, the Internet Service Providers cannot provide service plans known as tiered service whose price is different according to the user’s choice of quality of service levels. The term “Network Neutrality” was imported from Europe to the U.S. around 2003 when the FCC started defining the residential DSL as an Information Service.
Net neutrality is also a current controversial issue. Proponents agree the principle, saying that the Internet is communication media that is important for societies, and the information service should be accessed equally under special treatment of the law. On the contrary, other critics say that net neutrality would prevent the providers from offering high quality of service.
