High-Speed Inter-domain Fault Localization

Explore a 19-minute IEEE conference talk on high-speed inter-domain fault localization presented at the 2016 IEEE Symposium on Security & Privacy. Delve into Faultprints, the first secure data-plane fault localization protocol designed for inter-domain settings. Learn how this innovative approach enables precise localization of malicious network links that drop, delay, or modify packets. Discover the implementation details of Faultprints on a software router, leveraging the AES-NI module of Intel CPUs for enhanced efficiency. Examine the protocol's performance in real-world scenarios, including its impressive forwarding speed of 116.95 Gbps and goodput of 94 Gbps on commodity hardware. Gain insights into Faultprints' high failure localization rate and low communication overhead. The presentation covers an introduction to the topic, previous approaches, fault localization techniques, defense against storage exhaustion attacks, and a discussion of the protocol's advantages and limitations.
