Abstract (en)
[origin: WO2005109788A2] The present invention provides a packet processing device and method. A parsing processor provides instruction-driven content inspection of network packets at 10-Gbps and above with a parsing engine that executes parsing instructions. A flow state unit maintains statefulness of packet flows to allow content inspection across several related network packets. A state-graph unit traces state-graph nodes to keyword indications and/or parsing instructions. The parsing instructions can be derived from a high-level application to emulate user-friendly parsing logic. The parsing processor sends parsed packets to a network processor unit for further processing.
