  • System using stream specification and action specification stored in policy cache to process the flow of data packets by appropriate action processor
    Patent number: 7006502
    Abstract: A hardware-based policy engine that employs a policy cache to process packets of network traffic. The policy engine includes a stream classifier that associates each packet with at least one action processor based on data in the packet, and the action processor further acts on the packets based on the association determined by the stream classifier.

    Abstract: A method and apparatus for responding to denial of service attacks. Rather than a firewall or other device either denying all new session requests or denying no new session requests (and, albeit, dropping then-pending session requests), new session requests are selectively passed to the device.
