Abstract:
A method of providing hands-free services using a mobile device having wireless access to computer-based services includes receiving speech in a vehicle from a vehicle occupant; recording the speech using a mobile device; transmitting the recorded speech from the mobile device to a cloud speech service; receiving automatic speech recognition (ASR) results from the cloud speech service at the mobile device; and comparing the recorded speech with the received ASR results at the mobile device to identify one or more error conditions.
Abstract:
A method of managing a wireless connection at a mobile device includes detecting a short-range wireless signal at a mobile device; determining whether the short-range wireless signal is broadcast from a vehicular short-range wireless device or a non-vehicular short-range wireless device; and restricting one or more services available at the mobile device based on whether the short-range wireless signal is broadcast from a vehicular short-range wireless device or a non-vehicular short-range wireless device.
Abstract:
A method of determining a location of a network condition within a wireless mesh network is disclosed. The method includes a test device testing a first plurality of wireless hops of the wireless mesh network. The test device also tests a second number of wireless hops of the wireless mesh network. The test device locates the network condition within the wireless mesh network by comparing the test of the first plurality of wireless hops with the test of the second number of wireless hops.
Abstract:
A method of determining a state of a Storage Area Network SAN is provided comprising analyzing data collected from components in the SAN, calculating a redundancy level of the SAN based on the analyzed data, and determining the state of the SAN based on the calculated redundancy level. The redundancy levels indicate the sensitivity of the SAN to a fault in one of the components. The method also includes receiving user policy settings allowing automatic correction of the SAN and auto-correcting the SAN in response to a change in the SAN state and in dependence on the user policy settings. The redundancy levels can be used by an administrator to set the user policy settings. An apparatus for carrying out the method is also provided.
Abstract:
A methods and apparatuses of adaptively capping data throughput of client devices associated with a wireless network are disclosed. One method includes monitoring an air-time per bit efficiency of each client device associated with the wireless network. A data throughput cap for each client device is adaptively determined based on the air-time per bit efficiency of the client device.
Abstract:
A system and method of input/output (I/O) workload analysis of the components in a storage area network (SAN) is disclosed. In one embodiment, a method for analyzing I/O workloads of components in the SAN includes determining host bus adapter (HBA) to storage port oversubscription ratios and HBA to inter-switch link (ISL) oversubscription ratios in the SAN, selecting a subset of the components for monitoring based on the HBA to storage port oversubscription ratios and the HBA to ISL oversubscription ratios, continuously monitoring the subset of the components and storing I/O statistics of the subset of the components, and forecasting expected I/O workloads of the subset of the components based on current I/O workloads associated with the I/O statistics of the subset of the components and respective I/O workload threshold values of the subset of the components.
Abstract:
Methods of correlating wireless network performance of a wireless network are disclosed. One method includes collecting wireless network performance parameters at a location of the network, observing at least one of activities and conditions of the wireless network over the period of time, and correlating the wireless network performance parameters with at least one of the activities and conditions of the wireless network. The wireless network performance parameters can be collected by one or more test devices operating at nodes or clients within the wireless network.
Abstract:
An apparatus and method of a router within a wireless network providing mobility of a client device is disclosed. The method includes defining a routing table of the router, wherein the routing table provides next hop information towards the client device. Entries to the routing table are created, wherein the entries include a client device age that indicates when the client device associated with the wireless network.
Abstract:
A method of adaptively setting a transmission power level of a node within a wireless mesh network is disclosed. The method includes monitoring a quality of a plurality of reverse direction links between the node and downstream nodes, and between the node and an upstream node, of the wireless mesh network. At least one worst quality reverse direction link is identified. If the at least one worst quality link is greater than a high threshold, then the transmission power level of the node is decreased. If the at least one worst quality link is less than a low threshold, then the transmission power level of the node is increased. A method of adaptively selecting transmission power of gateway nodes of a wireless mesh network is also disclosed. The method includes each gateway node monitoring a quality of a plurality of reverse direction links between the gateway node and downstream nodes of the wireless mesh network. Each gateway node identifies at least one worst quality reverse direction link. For each gateway node, if the at least one worst quality link is greater than a high threshold, then decreasing the transmission power level of the gateway node is decreased. For each gateway node, if the at least one worst quality link is less than a low threshold, then the transmission power level of the gateway node is increased.
