Resumen
Nowadays the discussion about network neutrality is more and more necessary, many
countries are debating norms and laws to establish how the data traffic must be treated by the
ISP. In this context, it is important understand the techniques, motivations and the types of traffic
discrimination that can be realized by the ISP. From this knowledge, this Master dissertation
presents an agnostic method to detected the network neutrality breaking in a controlled environment.
Being an agnostic method for neutrality breaking detection, independently of the protocol,
application, service, packet size or any other information of the flow, this method works in
the same way. Other important factor is the utilization of multiple performance metrics (latency,
jitter, throughput and packet loss) to identify the neutrality breaking. The proposed method also
is capable to distinguish between traffic discrimination and natural degradation forms. All the
captured samples of each metric were transformed in an index with value between 0 (zero) and
1 (one), a simple statistic process (CEP) was used in the indexes transformation. To evaluate
the method, a controlled environment was developed with four different scenarios. In these
scenarios, the router simulates the configuration policies of an ISP. The simulations were of
neutral traffic, with packet discarding, with traffic shaping and with the router delaying the
packets. With the obtained results was possible evaluate that the proposed agnostic method
demonstrated itself effective in all tested scenarios.
