Abstract
A network device and a packet replication method are provided. The network device includes a classification engine, a forwarding engine, and a packet replication device. The packet replication device includes an interface circuit, a replication control circuit, and a storage unit. The interface circuit retrieves a packet of a flow from the forwarding engine and correspondingly outputs a replicated packet to the replication control circuit. The replication control circuit calculates a current rate corresponding to the replicated packet, checks a flow table for a cumulative number of replicated packets of the flow, and determines, according to the current rate and the cumulative number of replicated packets, to forward the replicated packet. The storage unit stores the flow table. The replication control circuit transmits the replicated packet to at least one application engine through at least one communication port for security inspection.
