Abstract:
Methods and systems for improving accuracy, speed, and efficiency of context-aware pattern matching are provided. According to one embodiment, a packet stream is received and pre-matched by an acceleration device with one or more conditions to identify packets meeting the one or more conditions. The acceleration device then correlates at least one identified packet based on the one or more conditions to generate matching tokens of the packet that meet the one or more conditions and sends, to one or more processors of the acceleration device, the matching tokens along with identifiers of the one or more conditions so that the processors can process the matching tokens and the identifiers of the one or more conditions based on one or more of context aware string matching, regular expression matching, and packet field value matching to extract packets that match context of the one or more conditions.
