    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： A solution for managing a communications connection, in which one or more acknowledgements are filtered is provided. In particular, data can be obtained for forwarding to a remote device, and at least some of the data can be communicated for processing on the remote device. Subsequently, an acknowledgement is received for the at least some of the data, and a determination is made as to whether to forward the acknowledgement based on an optimization configuration. The invention can include several checks to ensure that any acknowledgement that should be forwarded for further processing is properly forwarded. In one embodiment, the invention is implemented on a network adapter, and enables numerous acknowledgements that are received by the network adapter for a large send data packet to be filtered and not provided to a protocol stack.

    摘要： A method and system for reducing the lookup time in packet forwarding on computer networks. A first lookup is performed in a memory tree to find a first protocol forwarding entry in the memory tree. The forwarding entry includes first protocol (e.g., EGP) information and cached associated second protocol (e.g., IGP) information. Both EGP and IGP information are retrievable with the first lookup and used in the determination of an EGP route for the data packet. If the cached IGP information has been invalidated due to address updates, a second lookup can be performed to find an original IGP entry in the memory tree, the information from which can be cached in the EGP forwarding entry if a background maintenance task has finished designating all the EGP entries as having out-of-date caches.

    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.
