Deep Packet Inspection and its Effects On Net Neutrality

Deep packet inspection (DPI) is becoming increasingly important as a means to classify and control Internet traffic based on the content, applications, and users. Rather than just using packet header information, Internet Service Providers are using DPI for traffic management, routing and security. But by being able to control traffic by content, a growing number of public policy makers and users fear ISPs may discriminately charge more for faster delivery of their data, slow down applications or even deny access. They cite such practices as endangering the principle of net neutrality; the premise that all data on the Internet should be treated equally. The existing literature on DPI and net neutrality is sizeable, but little exists on the relationship between DPI and net neutrality. This study examines the literature, develops a research methodology and presents results from a study on the challenges of DPI in regards to privacy and net neutrality. The findings show that although most users are unaware of DPI technology, they feel strongly that it places their privacy at risk
