Over the past ten years, the debate over “network neutrality” has remained one of the central debates in Internet policy. Governments all over the world have been investigating whether legislative or regulatory action is needed to limit the ability of providers of Internet access services to interfere with the applications, content and services on their networks.
In addition to rules that forbid network providers from blocking applications, content and services, rules that forbid discrimination are a key component of any network neutrality regime. Non-discrimination rules apply to any form of differential treatment that falls short of blocking. Policy makers who consider adopting network neutrality rules need to decide which, if any, forms of differential treatment should be banned. These decisions determine, for example, whether a network provider is allowed to provide low-delay service only to its own streaming video application, but not to competing video applications; whether network providers can count only traffic from unaffiliated video applications, but not their own Internet video applications towards users’ monthly bandwidth cap; or whether network providers can charge different Internet access charges depending on the application used, independent of the amount of traffic created by the application.
