The practice of treating all content, information and users on the internet equally is generally referred to as Network Neutrality. Network Neutrality has become an important issue in the last few years as some ISP’s have attempted to “shape” internet connections by favouring certain types of content over others. Examples include slowing down large downloads or offering VOIP only to those paying to use that specific service.
Chile, and more recently the Netherlands have recently passed legislation defending the principle of network neutrality.
A recent controversy involving network neutrality was the deal between Google and Verizon in 2010. This deal stated that prohibitions against ISPs steering traffic based on users or content excluded wireless providers. In essence, it allows for wireless ISPs to mange traffic on their network in any way they choose.
