  • Link state tracking for virtual interfaces
    Patent number: 11362883
    Abstract: Presented herein are methodologies for tracking a link state of a physical network connection and selectively reporting the link state to virtual machines that rely on the physical network connection. A method includes receiving an indication, at a hypervisor, which is running on a host computer and which instantiates a virtual switch, that a physical link interconnecting the host computer to a network has failed; determining that the physical link serves the virtual switch; determining whether link state tracking is enabled for the physical link; and when link state tracking is enabled for the physical link, notifying a virtual machine, which is running on the host computer and which is being served by the virtual switch, that a connection between the virtual machine and the network has failed.

  • Vehicular fleet monitoring via public wireless communication access points using compressed diagnostic data sets and reduced latency transmissions
    Patent number: 7912641
    Abstract: A vehicular monitoring system is configured to acquire GPS position data and vehicular operating data, write the data to a file, and detect and utilize public wireless communication (e.g., 802.11x/WiFi) Internet access points to communicate the file containing the acquired GPS position data and vehicular operating data to a remote computer. Compressed diagnostic data sets and reduced latency wireless transmissions are utilized to facilitate communication.
