  • Method and apparatus for traffic control of dynamic denial of service attacks within a communications network
    Patent number: 8089871
    Abstract: A method and apparatus for providing traffic management for distributed denial of service (DDOS) traffic. Within a communications network, a DDOS detection system monitors network traffic to identify traffic that is designed to attack a particular server within the network and their entry points into the network. A traffic routing control unit is requested to deny service to the DDOS traffic. By selectively manipulating the routing information propagated to network edge routers, the traffic that is denied service is limited to mostly DDOS traffic and is routed to a cleaning center or a null address in the most effective fashion.

  • Management of ATM virtual circuits with resources reservation protocol
    Patent number: 6021263
    Abstract: A method and apparatus for use in a network utilizing Internet Protocol (IP), Resource Reservation Protocol (RSVP), and Asynchronous Transfer Mode (ATM) protocol is provided. An intelligent policy mapping database (PMD) accessible at the network level by both the RSVP and ATM protocol stacks maps RSVP parameters to ATM parameters with input from factors outside of the RSVP or ATM protocol stacks, e.g., general customer data. With the basis of customer data or other information outside of the RSVP and ATM protocol stacks, a network reservation message to the PMD contains RSVP flow specifications which are mapped to correlated ATM Quality of Service (QoS) parameters.
