Abstract

Mapping the topology of the internet is a challenge in itself, and studying its dynamics is even more difficult. However, achieving this would provide key information on the nature of the internet, crucial for modeling and simulation. Moreover, detecting anomalies in the dynamics is a key issue for security. A new measurement approach is introduced here that makes it possible to capture the dynamics of the internet at a scale of a few minutes in a radar-like manner. By conducting and analyzing large-scale measurements of this kind, we rigorously and automatically detect events in the observed dynamics, which is totally out of reach using previous approaches.
