Abstract
Distribution of network processing load among a set of packet processing devices is improved by employing means for eliminating, controlling, or otherwise affecting redundant packet processing operations. In one embodiment, at least two packet processing devices are present, both capable of processing data packets flowing therethrough, such as, inspecting, detecting, and filtering data packets pursuant to one or more filters from a filter set. Redundancy is controlled by providing or enabling either or both of the packet processing devices with capability for detecting during its said inspection of said data packets that, for example, one or more filters had been previously executed on said data packets by the other packet processing device, and then not executing the previously-executed filters on said data packets.
