Abstract
An apparatus and method of protecting against a denial-of-service (DoS) attack are described. The apparatus comprises a classification engine, a meter engine, and a copy engine. The method comprises assigning a received packet to a meter based upon a classification of the network packet, determining that a DoS attack is in progress based upon a meter count, copying at least one packet from the meter to a processor; and suppressing the copying of subsequently received network packets to the processor.
