  • Stateful firewall protection for control plane traffic within a network device
    Patent number: 8020200
    Abstract: A network device receives control plane packets and data plane packets from a network. The network device includes a forwarding component that forwards the data plane packets in accordance with routing information maintained by a routing component. The forwarding component directs the control plane packets to a firewall component that processes the control plane packets to apply firewall services and detect network attacks. After processing, the firewall component loops the control plane packets back to the forwarding components for forwarding to the routing component. The firewall component may be a security service card.
