ABSTRACT:
A method for searching network messages for pre-defined regular expressions is disclosed. A plurality of pre-defined regular expressions are stored in a content-addressable memory (CAM). A network message or selected portion thereof is inputted to the CAM for comparison with all of the regular expressions stored therein, the comparison with all CAM entries being done at the same time. An output is returned from the CAM. In response to the output from the CAM, identifying an action to be applied to the given network message or portion thereof that corresponds to a CAM entry matching the inputted network message or selected portion thereof.
