Summer School on Internet Path Transparency Measurements

On June the 11th the Electronics Research Group hosted the MAMI Summer
School on Internet Path Transparency Measurements in Aberdeen, Scotland.
This consisted of a few hands-on workshops, with participation
both on-site and remote via video conference.

The summer school started with Korian and Justin demonstrating Tracebox
through a variety of topologies. The participants then worked on their
own trying to uncover middleboxes and hidden topologies using a variety
of tools, including tracebox and paris-traceroute.

To follow, the history and development of PATHspider were presented by
Iain Learmonth, one of the creators of PATHspider. Iain also delivered
an interactive Scapy tutorial followed by teaching students how to use
Scapy to create PATHspider plugins using the Evil Bit as an example.
The participants ran plugins against a list of real targets and produced
results.

To finish off, Brian Trammel delivered a presentation on the PTO (Path
Transparency Observatory), and helped the participants upload to it the
results they collected in the previous session. The participants then
learned how to query the PTO in order to examine the data they just
uploaded. In an interesting twist of events, the measurements found ECN
manipulation by a middlebox in the eduroam network in Aberdeen – mission
accomplished!
