The PAADDoS project’s goal is to defend against large-scale DDoS attacks by making anycast-based capacity more effective than it is today. Anycast use Internet routing to associate users with geographically close sites of a replicated service. During DDoS, anycast sites can provide capacity to absorb an attack, and they can be used to isolate the attack to part of the network.
We will work toward our goal of improving anycast use during DDoS by (1) developing tools to map anycast catchments and baseline load, (2) develop methods to plan changes and their effects on catchments, (3) develop tools to estimate attack load and assist anycast reconfiguration during an attack. and (4) evaluate and integration of these tools with traditional DoS defenses.
We expect these innovations to improve service resilience in the face of DDoS attacks. Our tools will improve anycast agility during an attack, allowing capacity to be used effectively.
