Abstract
A network device to detect large flows includes a card to receive packets of flows. The device includes a large flow detection module including a serial multiple-stage filter module including series filter modules including a lead filter module and a tail filter module. Each filter module includes counters. The serial filter module is to serially increment the counters to reflect the flows, and is to increment counters that correspond to flows of subsequent filter modules only after all counters that correspond to the flows of all prior filter modules have been incremented serially up to maximum values. The serial filter module is to detect flows that correspond to counters of the tail filter module that have been incremented up to maximum values as the large flows. The large flow detection module includes a lead filter removal module to remove the lead filter module from the start of the series.
