Abstract
A method for selectively processing a packet flow using a flow inspection engine is disclosed. The method includes receiving, by at least one hardware data plane processor component in a network packet broker, a plurality of packets associated with a packet flow, and forwarding, by the at least one hardware data plane processor component to at least one flow inspection engine, a copy of at least a portion of one or more of the initial packets of the packet flow. The method further includes providing, by the at least one hardware data plane processor component to the at least one flow inspection engine, packet flow statistical data resulting from a high throughput processing of the plurality of packets by the at least one hardware data plane processor component and generating, by the at least one flow inspection engine, metadata records using the copy at least a portion of the of the one or more of the initial packets and the packet flow statistical data, wherein the at least one hardware data plane processor component generates the statistical data from the plurality of packets independent of any instruction from the at least one flow inspection engine.
