Abstract
A network router includes a plurality of interfaces configured to send and receive packets, and a routing component comprising: (i) a routing engine that includes a control unit that executes a routing protocol to maintain routing information specifying routes through a network, and (ii) a forwarding plane configured by the routing engine to select next hops for the packets in accordance with the routing information. The forwarding plane comprises a switch fabric to forward the packets to the interfaces based on the selected next hops. The network router also includes a security plane configured to apply security functions to the packets. The security plane is integrated within the network router to share a streamlined forwarding plane of the routing component.
