Network neutrality ("net neutrality" or "Internet neutrality") refers to a broadband network free of restrictions on the kinds of equipment that may be attached and the modes of communication allowed, and where communication was not unreasonably degraded by other communication streams. The principle of net neutrality and regulations designed to support the neutrality of the Internet have been subject to many debates. Since the early 2000s, advocates of net neutrality rules have warned of the danger that broadband providers will use their power over the "last mile" to block applications they do not favor, and also to discriminate between content providers (e.g. websites, services, protocols), particularly competitors. Neutrality proponents also claim that telecom companies seek to impose the tiered service model more for the purpose of profiting from their control of the pipeline rather than for any demand for their content or services. Others have stated that they believe "net neutrality" to be primarily important as a preservation of current freedoms. As co-inventor of the Internet Protocol Vint Cerf has stated, "The Internet was designed with no gatekeepers over new content or services. A lightweight but enforceable neutrality rule is needed to ensure that the Internet continues to thrive."
