Abstract
A network security device includes a network flow statistics processing engine to process network flow information related to network flows. The network flow statistics processing engine includes a first processing stage performing per-flow information aggregation and a second processing stage performing per-destination system component information aggregation, with each processing stage implementing a threshold-based data export scheme and a timer-based data export scheme. In this manner, up-to-date flow information is available to peer system components regardless of the varying flow rates of the network flow.
