Abstract
A network security device receives a traffic flow through an input port from a source device and forwards the traffic flow through a primary output port to a primary switch. The network security device switches from the primary output port to a backup output port when determining that the traffic flow fails to be forwarded by the primary switch to a destination device, and forwards the traffic flow through the backup output port to a backup switch. The traffic flow that is forwarded from the primary switch to the destination device is changed to be forwarded through the backup switch to the destination device.
