Research on the net neutrality: The case of Comcast blocking

Net neutrality has caused a raging concern about Internet's open, accessible and innovative features. This paper summarizes the concept and origination of net neutrality, as well as the typical opinions of the proponents and opponents on net neutrality. It takes Comcast as an example, analyses the reason and measurement that Internet Service Providers (ISPs) enforced discriminatory access and blocking. We argue that peer-to-peer (P2P) softwares don't harm the whole quality of Internet; they just transfer the pressure from Content Providers (CPs) to ISPs. And the only loss caused by P2P protocols is that ISPs can't get premium revenues from CPs. We suggest that net neutrality should be preserved and regulated. Meanwhile, the government should stimulate the investment incentives of ISPs to encourage the deployment and optimization of new broadband network. If market forces can't achieve this goal, some market measures would be necessary.
