English abstract:
Internet service providers can discriminate traffic in certain
ways, e.g., by the used protocol or application. This leads
to advantages for providers, but also harms the freedom and
innovation in the Internet. However, ISPs currently use a
variety of technical measures. Some can be seen as questionable regarding net neutrality { an important topic in
legal and economic discussions. These methods are often
neither technically identified nor continuously monitored,
which prevents an informed discussion about the legitimacy
of such methods. In this paper, we design and implement
an open-source framework for monitoring such techniques
within a country. Compared to other projects, we are able
to fully control the client and server endpoint and therefore
analyze network behavior in depth. We implement 17 different metrics that cover a wide range of the network spectrum.
We test basic network features on transport layer as well as
specific application layer protocols. We then use this frame-
work to monitor five different Internet products in Austria
over the time span of more than one year. We evaluate the
results from our three measurement periods of three months
each and find different questionable methods in place. This
includes e.g., middleboxes used for various protocols, mon-
etization of DNS results and different behavior for special
DNS queries. However, many metrics show that currently no
questionable techniques are used.
