  • Publication number: 20200167300
    Abstract: A network switch includes a data bus, a register, an endpoint controller and a direct memory access controller. The endpoint controller is configured to receive a descriptor generated by a device driver of a host system, store the descriptor in the register, and transfer data between a root complex controller of the host system and the data bus. The descriptor identifies an address of a buffer in a memory of the host system. The direct memory access controller is configured to receive the address of the buffer from the endpoint controller or the register and, based on the address and an indication generated by the device driver, independently control transfer of the data between the memory of the host system and a network device connected to the network switch. The direct memory access controller is a receive direct memory access controller or a transmit direct memory access controller.

  • Patent number: 10469633
    Abstract: A conversion pipeline includes a media input stage, a packetizer, a MAC engine and a PHY interface. The media input stage is configured to receive from a media source a sequence of media frames carrying media content. The packetizer is configured to convert the media frames into a sequence of Ethernet packets by generating headers and appending portions of media frames to corresponding generated headers, including appending a first portion of a first media frame to a first generated header before the first media frame is fully received. The MAC engine is configured to commence outputting a first Ethernet packet as an uninterrupted unit, the first Ethernet packet including the first header and payload bits corresponding to the first portion of the first media frame, before the first media frame is fully received. The PHY interface is configured to transmit the Ethernet packets over a network.

  • Patent number: 7920536
    Abstract: In a wireless network having one or more base stations and one or more access points, the base station is switched automatically from a CSMA/CA exchange protocol to an RTS/CTS exchange protocol, in a case where the base station infers the presence of a hidden node. The presence of a hidden node is inferred by scanning frames of wireless network transmissions to and from other base stations and the access point. In a case where there is a discrepancy in the accrued frames, such that frames have been accrued from the access point to a second base station without also accruing frames from the second base station back to the access point, the presence of a hidden node is inferred, and the base station is switched automatically to RTS/CTS exchange mode.

  • Patent number: 7881185
    Abstract: A network device includes a first plurality of ports and a first plurality of communication links. Each port of the first plurality of ports communicates with a corresponding communication link of the first plurality of communication links. An adapter aggregates the first plurality communication links into a second plurality of aggregated links. The adaptor assigns a single media access control address to each aggregated link of the second plurality of aggregated links. A driver selects a first aggregated link of the second plurality of aggregated links as an active link based on a link quality of the first aggregated link. The driver sends and receives data over the first aggregated link using the single media access control address assigned to the first aggregated link. The driver selects a second aggregated link of the second plurality of aggregated links as the active link in response to the link quality of the first aggregated link being less than a link quality of the second aggregated link.

  • Patent number: 4809555
    Abstract: A pressure sensor has a metal housing. The housing has a closed-off and fluid-filled pressure space. A diaphragm partitions the pressure space off from the environment and transmits pressures derived therefrom to the fluid. A pressure-sensitive chip of semiconducting material is exposed to the pressure of the fluid and has a piezoresistant and anisotropic effect. Connectors, metal rods for instance, extend pressure-tight and electrically insulated from the metal housing into the pressure space. The connectors can be connected to an electric processing circuit. The pressure-sensitive chip is connected by bonds. To provide a pressure sensor that will be cheaper to manufacture, less sensitive to malfunction, and more precise, the pressure sensor is provided with a base plate of aluminum nitride. At least some areas of its surface are metallized. The pressure-sensitive chip is soldered to the base plate within a metallized area.
