摘要：Apparatus for detecting a pattern in a data stream comprises a patternmatching device for receiving the data stream. The pattern matching device comprisesone or more rule engines, each rule engine operating under a plurality of state transitionrules encoding a plurality of patterns, a first state transition rule including a wildcard
state component and a wildcard input component, a second state transition ruleincluding a wildcard state component and a specified input component, and a third statetransition rule including a specified state component and a specified input component,the first, second and third rules having differing priorities, and at least one state
transition rule including an output component indicating a pattern match. The apparatusis arranged to pass the data stream to each rule engine, and is further arranged tooutput a signal indicating a pattern match when a state transition rule indicates a patternmatch.
