  • Publication number: 20110310892
    Abstract: Systems, devices and methods for improving network performance are disclosed. In particular, in one embodiment, a method of processing data packets in an electronic network is provided. The method includes receiving data packets at a receive stack of an electronic network device and creating a first packet from at least a portion of each of the set of data packets. The first packet includes an indicator that the first packet is a first packet type. The creation of the first packet includes saving a first header of the plurality of data packets, modifying the first header with information from each of the set of data packets, and concatenating the set of data packets.

  • Patent number: 8848713
    Abstract: Systems, devices and methods for improving network performance are disclosed. In particular, in one embodiment, a method of processing data packets in an electronic network is provided. The method includes receiving data packets at a receive stack of an electronic network device and creating a first packet from at least a portion of each of the set of data packets. The first packet includes an indicator that the first packet is a first packet type. Additionally, the method includes passing the first packet to one of a bridge and IP layer of the receive stack. A first packet inhibitor at the one of the bridge and IP layer is bypassed upon recognizing the first packet as a first packet type. The first packet is routed to a transmit stack of the electronic network device from the one of the bridge and IP layer.

  • Patent number: 7512128
    Abstract: A kernel data transfer method and system for transmitting multiple packets of data in a single block of data presented by application programs to the kernel's network subsystem for processing in accordance with data transfer parameters set by the application program. The multi-packet transmit system includes logic that allows header information of the multiple packets of data to be generated in a single buffer and appended to a second buffer containing the data packets to be transmitted through the network stack. The multi-data transmit system allows a device driver to amortize the input/output memory management related overhead across a number of packets. With some assistance from the network stack, the device driver needs to only perform the necessary IOMMU operations on two contiguous memory blocks representing the header information and the data payload of multiple packets during each transmit call.
