  • Patent number: 9577874
    Abstract: A method is disclosed that is implemented by a router for executing an internet protocol fast reroute process in response to a network event invalidating a current route to a destination node without degrading forwarding plane functionality or performance caused by indirect forwarding information base lookups. The method comprises a set steps including receiving or generating the network event by the router, the network event associated with a network event identifier and looking up the network event identifier in an event table to determine routes that are affected by the network event. The method further includes determining whether a route with a fast reroute forwarding object is affected by the network event in the routing information base and overwriting a current next hop forwarding object using a backup next hop forwarding object in the forwarding information base.

  • Patent number: 9568554
    Abstract: Devices and methods are disclosed which relate to a wireless communications device comprising a wireless power transmission detector and a wireless power transmission indicator for displaying to a user the current level of wireless power transmission. A voltmeter and ammeter take readings from the wireless transceiver circuit while the wireless communications device is on. A power logic stored on a memory within the wireless communications device converts the readings into a wireless power transmission level. The wireless power transmission level is output to an indicator on the wireless communications device where a user can view it. Exemplary embodiments include a true battery life indicator on the wireless communications device. The true battery life indicator gives an amount of time a battery powering the wireless communications device will last at the current wireless power transmission level.

  • Patent number: 9549357
    Abstract: The present disclosure describes promoting roaming of a wireless terminal in a wireless local area network (WLAN). The AP obtains signal quality and/or data transmission quality of the wireless terminal periodically, and determines whether the obtained signal quality and/or data transmission quality of the wireless terminal satisfies a predetermined threshold. Upon determining that the predetermined threshold is not satisfied, the AP proactively sends a probe response frame to the wireless terminal. The probe response frame notifies the wireless terminal of a wireless signal strength of the AP to promote roaming to a neighboring AP.
