JurisNN: Judging traffic differentiations as network neutrality violations according to the regulation

Network Neutrality (NN) is a principle that is not taken for granted on the Internet. Instead, it must be enforced by regulation that defines which Traffic Differentiation (TD) practices are allowed or prohibited from being adopted by ISPs. Thus, the regulation is the proper source of NN definitions to design solutions for detecting NN violations. However, the regulation set by legislators is valid within a geographical area named jurisdiction. Therefore, as an end-to-end network path may traverse multiple jurisdictions, distinct NN definitions along with this path must be considered. Thus, to be effective, solutions based on the regulation must consider where in the end-to-end network path the TD was deployed to evaluate the proper NN definitions stated there. We propose a solution named JurisNN that implements the functionalities required to judge TDs as NN violations considering the regulation. To evaluate the JurisNN judgments, we use TD information collected by a state-of-the-art solution to assess whether this information is enough to judge TDs as NN violations by analyzing the conclusiveness of the results (the TD is an NN violation or not). The results show that to help the signaling of NN violations according to the regulation solutions need both to collect the network paths traversed by tests and to pinpoint where the TD was deployed with better accuracy.
