  • Patent number: 9065677
    Abstract: A hybrid device can apply forwarding tables associated with one or more other hybrid network devices of a hybrid communication network to control the entire transmission route of a frame scheduled for transmission. The hybrid device can use its forwarding table and a forwarding table of a destination hybrid device to determine a source network interface address, a destination network interface address, and a frame transmission route. The destination hybrid device can use forwarding tables associated with one or more hybrid network devices to determine whether to process or drop a received frame, whether the frame was previously received, and/or whether the frame was received on an incorrect network interface. The hybrid device can also use the forwarding tables to ensure that the frame comprises an appropriate link layer address and to select an appropriate transmission route based on analyzing link performance values associated with multiple transmission routes.

  • Patent number: 8953574
    Abstract: A hybrid device can be configured to use WLAN communication links for bridging network traffic between any pair of network devices in a hybrid communication network, irrespective of whether the bridged network devices support WLAN communication. The hybrid device receives a first data frame in a first frame format for transmission to a destination device. The hybrid device accesses its hybrid forwarding tables and identifies a transmit interface from which to transmit the first data frame for transmission to the destination device. If the transmit interface is a WLAN interface, WLAN forwarding tables associated with the WLAN transmit interface are accessed to identify a receiving WLAN device to which the first data frame should be transmitted. The WLAN transmit interface converts the first data frame into a second data frame in a WLAN frame format and transmits the second data frame to the receiving WLAN device.

  • Patent number: 8325107
    Abstract: The present invention provides a method and apparatus for optimizing the transmission of video configuration data in a system comprising a host computer and a display monitor. The invention comprises a wireless video source adapter connected to the host computer and a wireless video sink adapter connected to the monitor. Upon system startup, the video sink adapter acquires EDID information from the monitor and transmits it to the video source adapter, which does not activate its connection and indicate its presence to the host computer until after receiving the EDID information. The video source adapter then supplies the EDID information to the host computer in response to EDID requests from the computer. In this manner, the video source adapter acts as a virtual proxy for the display monitor from the point of the view of the host computer. The host computer then uses the EDID information to configure its video signal to match the parameters of the display monitor.
