Abstract
A denial-of-service network attack detection system is deployable in single-homed and multi-homed stub networks. The detection system maintains state information of flows entering and leaving the stub domain to determine if exiting traffic exceeds traffic entering the system. Monitors perform simple processing tasks on sampled packets at individual routers in the network at line speed and perform more intensive processing at the routers periodically. The monitors at the routers form an overlay network and communicate pertinent traffic state information between nodes. The state information is collected and analyzed to determine the presence of an attack.
