    摘要： A system and method of protocol and frame classification in a system for data processing is disclosed, including, analyzing a portion of the, packet or frame according to predetermined tests, and storing characteristics of the packet for use in subsequent processing of the frame. The characteristics are preferably obtained with hardware, which does so quickly and in a uniform time period. The stored characteristics of the packet are then used by the network processing complexes in further processing of the frame. The processor is preconditioned with a starting instruction address or cede entry point and the location of the beginning of the layer 3 header as well as flags for the type of frame.

    摘要： A system and method of protocol and frame classification in a system for data processing (e.g., switching or routing data packets or frames). The present invention includes analyzing a portion of the packet or frame according to predetermined tests, then storing key characteristics of the packet for use in subsequent processing of the frame. The key characteristics for the frame (or input information unit, such as the type of layer 3 protocol used in the frame, the layer 2 encapsulation technique, the starting instruction address and flags indicating whether the frame uses a virtual local area network, preferably using hardware to quickly and in a uniform time period. The stored key characteristics of the packet are then used by the network processing complexes in its further processing of the frame. The processor is preconditioned with a starting instruction address and the location of the beginning of the layer 3 header as well as flags for the type of frame. That is, the instruction address or code entry point is used by the processor to start processing for a frame at the right place, based on the type of frame. Additionally, additional instruction addresses can be stacked and used sequentially at branches to avoid additional tests and branching instructions.

    摘要： A system and method of data flow management, particularly in a multiple network processor architecture where a plurality of independent processing units are simultaneously processing information from different frames of input information. The present invention includes first-in-first-out files identifying the individual frames and correlating the frames with the processor to which the frames have been assigned for processing as well as a first-in-first-out file of processed frames for each processor to allow the frames to be processed independently, then reassembled into the same order as the frames had been received without communication between the independent processors. Additionally, the present system supports newly-created frames as well as the concept of flushing the system without regard to frame order whereby frames are sent out to the network as the processing is completed without regard to input order, overriding the system of putting the output frames in the same order as the input frames were received from the network.
