1. a kind of packet parsing processor, including:

  • Analytics engine, the analytics engine have the input for receiving the signal for representing network packet, and in response to parsingInstruction executes instruction the network packet packet parsing of driving;

    Stream mode unit, input of the stream mode unit with the first input/output for being coupled to the analytics engine/defeatedGo out, and the analysis state in stream mode unit storage stream of packets;

    AndState-graph unit, the state-graph unit includes multiple state diagrams, wherein each state diagram includes the transfer of multiple nodesAnd each node corresponds to a kind of state, and the state-graph unit, which has, is coupled to the second input of the analytics engine/defeatedThe input/output gone out, and for storing the analysis instruction in the state address of the node in representing state diagram, whereinAnalysis instruction is associated with the node in the state diagram, parsing shape of the analytics engine in response to the network packetState matches to execute the analysis instruction with the state of the node in the state diagram.
