ABSTRACT:
A method for controlling a denial of service attack involves receiving a plurality of packets from a network, identifying an attacking host based on a severity level of the denial of service attack from the network, wherein the attacking host is identified by an identifying attack characteristic associated with one of the plurality of packets associated with the attacking host, analyzing each of the plurality of packets by a classifier to determine to which of a plurality of temporary data structures each of the plurality of packet is forwarded, forwarding each of the plurality of packets associated with the identifying attack characteristic to one of the plurality of temporary data structures matching the severity level of the denial of service attack as determined by the classifier, requesting a number of packets from the one of the plurality of temporary data structures matching the severity level by the virtual serialization queue, and forwarding the number of packets to the virtual serialization queue.
