Abstract

A packet filter (2500) for incoming communications packets includes extractor circuitry (2510) operable to extract data from a packet, and packet processor circuitry (2520) operable to concurrently mask (3010) the packet data from the extractor circuitry (2510), perform an arithmetic/logic operation (3020) on the packet to supply a packet drop signal (DROP), and perform a conditional limit operation and a conditional jump operation (3030).
