The PAADDoS project’s goal is to defend against large-scale Distributed Denial-of-Service (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) developing methods to plan changes and their effects on catchments,
and (3) developing tools to estimate attack load and assist anycast reconfiguration during an attack.
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.
PAADDoS is a joint effort of the ANT Lab
involving USC/ISI (PI: John Heidemann)
and the Design and Analysis of Communication Systems group
at the University of Twente (PI: Aiko Pras).
PAADDoS also builds on our collaboration with SIDN Labs.
PAADDoS has websites at USC and U. Twente.
PAADDoS is supported by
the DHS HSARPA Cyber Security Division
via contract number
and by NWO.
