Abstract
A network router includes interfaces to receive packets, a routing engine that executes a routing protocol to maintain routing information specifying routes through a network, a packet forwarding engine forward the packets to the interfaces in accordance with the routing information, one or more advertising engine service cards comprising a packet inspection engine and an advertising engine control unit, and a set of dynamic filters that identify packets for inspection by the packet inspection engine based on characteristics of the packet. The filters direct any matching ones of the packets from the packet forwarding engine to the packet inspection engine within the advertising engine service card, and the packet inspection engine analyzes the packets to extract information from the packets based on configured advertising engine policies. The advertising engine control unit outputs commands to dynamically add and delete filters from the set of dynamic filters.
