Abstract
Network packet forwarding systems and methods are disclosed to push pre-processing tasks to network tap devices. In certain embodiments, packet flows from multiple monitoring points within a packet network communication system are monitored by a plurality of network tap devices to generate tapped packet flows associated with monitored network traffic flows. The tapped packet flows are transmitted from each network tap device to a tap controller, and the tap controller generates pre-processing rules based upon the tapped packet flows. Control messages including the pre-processing rules are then transmitted from the tap controller to the network tap devices, and the tapped packet flows are pre-processed at the network tap devices using the pre-processing rules to generate pre-processed packet flows. These pre-processed packet flows are then transmitted back to the tap controller where they are further processed and output to one or more destination devices.
