Cornstarch effect: intensifying flow resistance for increasing DDoS attacks in autonomous overlays

Abstract

Overlay networks are vital to the continued evolution of web services and content distribution. We propose a reactive mechanism to mitigate flooding attacks in overlay networks. Our approach enhances detection and filtering capability in accordance to the size of an attack. As the DDoS traffic flow increases, we intensify detection and scrubbing in a decentralized manner. Flow resistance increases to minimize penetration and attack flows from reaching their destination. We demonstrate their effectiveness in simulations.
