Abstract

A network security appliance uses a switch to switch packets between cores configured for fast path processing and slow path processing. The switch duplicates packets for delivery to the slow path processing cores, eliminating the need for the fast path processing cores to expend processor resources on packet duplication. The switch can use IEEE 802.1ad Q-in-Q VLAN tags in the packet to perform the switching and packet duplication. Slow path processing cores may also broadcast packets to other slow path processing cores via the switch.
