What are the Open Internet rules?

Adopted by the FCC in late 2010, the Open Internet regulations are supposed to provide a set of rules to ensure that broadband service providers preserve open access to the Internet.

There are three main rules at the heart of the regulation. The first required that broadband providers, whether they're fixed-line providers or wireless operators, are open and transparent to their customers and to the services using their networks about how they manage congestion on the systems.

The second rule prohibited broadband operators from blocking lawful content on their networks. Here, there's some difference in strictness depending on whether the provider deals in fixed-broadband or wireless services. Fixed-broadband providers, such as cable operators and DSL providers, have abided by a more stringent set of rules, and wireless operators adhered to a less strict version of the rules.
And the third rule, which applied only to fixed-broadband providers, prohibited "unreasonable" discrimination against traffic on their networks.
