Internet-Wide Measurement of Network Layer Disruption


Augur provides a method and accompanying system that utilizes TCP/IP side channels to measure reachability between two Internet locations without directly controlling a measurement vantage point at either location. Using routers with globally incrementing IP ID counters, coupled with techniques to ensure safety by not implicating individual users, we develop scalable, statistically robust methods to infer network-layer filtering, and implement a corresponding system capable of performing continuous monitoring of global Internet disruption.


All the data collected from the Observatory is publicly available, including metadata.


Augur was presented at the 2017 IEEE Symposium on Security & Privacy.
