摘要： A method for performing a lookup for a packet in a computer network are disclosed. The packet includes a header. The method includes providing a parser, providing a lookup engine coupled with the parser, and providing a processor coupled with the lookup engine. The parser is for parsing the packet for the header prior to receipt of the packet being completed. The lookup engine performs a lookup for the header and returns a resultant. In one aspect, the lookup includes performing a local lookup of a cache that includes resultants of previous lookups. The processor processes the resultant.

摘要： Systems and methods for implementing multi-frame control blocks in a network processor are disclosed. Embodiments include systems and methods to reduce long latency memory access to less expensive memory such as DRAM. As a network processor in a network receives packets of data, the network processor forms a frame control block for each packet. The frame control block contains a pointer to a memory location where the packet data is stored, and is thereby associated with the packet. The network processor associates a plurality of frame control blocks together in a table control block that is stored in a control store. Each table control block comprises a pointer to a memory location of a next table control block in a chain of table control blocks. Because frame control blocks are stored and accessed in table control blocks, less frequent memory accesses may be needed to keep up with the frame rate of packet transmission.

摘要： Systems and methods for implementing counters in a network processor with cost effective memory are disclosed. Embodiments include systems and methods for implementing counters in a network processor using less expensive memory such as DRAM. A network processor receives packets and implements accounting functions including counting packets in each of a plurality of flow queues. Embodiments include a counter controller that may increment counter values more than once during a R-M-W cycle. Each time a counter controller receives a request to update a counter during a R-M-W cycle that has been initiated for the counter, the counter controller increments the counter value received from memory. The incremented value is written to memory during the write cycle of the R-M-W cycle. A write disable unit disables writes that would otherwise occur during R-M-W cycles initiated for the counter during the earlier initiated R-M-W cycle.

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.
