This presentation focuses on the resiliency of the French Internet, studied from thepoint of view of network interconnectivity. We define a model for representing theBGP-level topology of the Internet which takes into account the businessrelationships between ASes, and implement an algorithm to construct such a map from publicly available routing information.The portion of the Internet responsible for the connectivity of French ASes is thenestablished, and the risk of disconnection is assessed. To this end, we identify asset of critical ASes whose suppression would disconnect other ASes from the Internet. Finally, we give some insight as to how the model could be expanded and thedifficulties this would introduce. We also give an example of how a BGP-level map ofthe Internet can be used to actively monitor the network.
