ABSTRACT:
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.
