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 method and structure for determining when a frame of information comprised of one or more buffers of data being transmitted in a network processor has completed transmission is provided. The network processor includes several control blocks, one for each data buffer, each containing control information linking one buffer to another. Each control block has a last bit feature which is a single bit settable to “one” or “zero” and indicates when the data buffer having the last bit is transmitted. The last bit is in a first position when an additional data buffer is to be chained to a previous data buffer indicating an additional data buffer is to be transmitted and a second position when no additional data buffer is to be chained to a previous data buffer. The position of the last bit is communicated to the network processor indicating the ending of a particular frame.

摘要： Data structures, a method, and an associated transmission system for multicast transmission on network processors in order both to minimize multicast transmission memory requirements and to account for port performance discrepancies. Frame data for multicast transmission on a network processor is read into buffers to which are associated various control structures and a reference frame. The reference frame and the associated control structures permit multicast targets to be serviced without creating multiple copies of the frame. Furthermore this same reference frame and control structures allow buffers allocated for each multicast target to be returned to the free buffer queue without waiting until all multicast transmissions are complete.

摘要： A method and structure for determining when a frame of information comprised of one or more buffers of data being transmitted in a network processor has completed transmission is provided. The network processor includes a plurality of control blocks, one for each data buffer, each containing control information to link one buffer to another for transmission. Each of the control blocks has a last bit feature which is a single bit and indicates when the data buffer having the last bit is transmitted. This last bit feature is a bit which can be set to either zero or one. The last bit feature is in a first position when an additional data buffer is to be chained to a previous data buffer indicating an additional data buffer is to be transmitted and a second position when no additional data buffer is to be chained to a previous data buffer. The position of the last bit feature is communicated to the network processor to indicate whether the transmission of a particular frame is ended and a new frame is to be transmitted.
