摘要： In one embodiment, a device in a network assigns packets from a communication transmitted via the network to time windows over a period of time. The device determines a transmission performance metric for each of the packets in a particular time window and calculates, for each of the time windows, local disturbance scores, which are based on the transmission performance metrics for the packet in the time windows. A particular local disturbance score for a particular time window maps the transmission performance metrics for the packets in the time window to a perceived quality metric. The device determines a distortion score for the communication by aggregating the local disturbance scores for the time windows over the period of time.

摘要： In one implementation, a method of maintaining continuous identity for mobile devices includes: obtaining a first address for a first device; and obtaining, from one or more auxiliary sensors, auxiliary sensor information related to the first device. The method also includes determining whether the auxiliary sensor information matches information associated with a second address, where the second address was previously associated with the first device. The method further includes linking the first address with the second address for the first device, in order to continue tracking the first device when the second address is no longer detected, in response to determining that the auxiliary sensor information matches information associated with the second address.

摘要： Systems, methods, and computer-readable media for controlling link selection and aggregation across multiple wireless networks based on a location of a mobile device. A location of a mobile device in a physical environment can be identified. At least portions of the physical environment can be in wireless range of a first wireless network and a second wireless network. Whether to access network services through either or both the first wireless network and the second wireless network can be determined based on the location of the mobile device in the physical environment. Further, a first interface at the mobile device to the first wireless network and a second interface at the mobile device to the second wireless network can be selectively toggled according to whether it is determined to access the network services through either or both the first wireless network and the second wireless network based on the location.

摘要： In one embodiment, a device in a serial network de-multiplexes a stream of traffic in the serial network into a plurality of data streams. The device determines that data from a particular data stream should be reported to an entity external to the serial network based on an event indicated by the data from the particular data stream. The device quantizes the data from the particular data stream. The device applies compression to the quantized data to form a compressed representation of the particular data stream. The applied compression is selected based on a data type associated with the data. The device sends a compressed representation of the particular data stream to the external entity as Internet Protocol (IP) traffic.

摘要： In one embodiment, a device determines locations of a plurality of transmitters relative to a particular wireless access point in a wireless network. One of the transmitters comprises a target client to which the particular wireless access point is to communicate. The device compares a plurality of beamforming patterns associated with the particular wireless access point to the determined locations. The device selects, based on the comparison, one of the beamforming patterns for use by the particular wireless access point to communicate with the target client. The device controls the particular wireless access point to use the selected beamforming pattern to communicate with the target client.

摘要： In one embodiment, a device in a wireless power transfer (WPT) system receives data regarding a vehicle equipped with a vehicle-based charging coil configured to receive electrical power transferred from a ground-based charging coil of the WPT system. The device determines, based on the received data, a time at which the vehicle-based charging coil is expected to be in charging proximity of the ground-based coil. Based on the received data, the device determines a gap distance between the vehicle-based charging coil and the ground-based charging coil to optimize the transfer of electrical power from the ground-based charging coil to the vehicle-based charging coil when the coils are in charging proximity of one another. The device sends control instructions to an adjustment system to implement the identified gap distance in advance of the determined time by adjusting a height of the vehicle-based charging coil or the ground-based charging coil.

摘要： In one embodiment, a prediction agent process collects travel information of a vehicle, and determines a profile of the vehicle, the profile indicative of one or more real-time resource requirements of the vehicle. The prediction agent process also predicts a path of the vehicle based on the travel information, and determines a next resource node along the predicted path having one or more real-time resources corresponding to the one or more real-time resource requirements of the vehicle. After further predicting a time of arrival of the vehicle being within range of the next resource node based on the travel information, the prediction agent process informs the next resource node of the profile of the vehicle and the predicted time of arrival, the informing causing the next resource node to operate the one or more real-time resources for the vehicle for the predicted time of arrival.

摘要： A controller device is configured to communicate with storage nodes of a distributed storage system (DSS) in which erasure codes are used to encode source data onto the storage nodes and ranks of matrices containing coding coefficients associated with the erasure codes indicate whether repairs of failed storage nodes of the DSS are feasible. A decomposition structure is generated to be used as a guide for transforming the matrices to upper triangle form (UTF) for use in computing the ranks of the matrices. While the DSS is operating to perform repairs of the failed storage nodes, as part of determining feasible repair strategies that will preserve subsequent repairs of failed storage nodes, the ranks of the matrices are computed by transforming the matrices to UTF using operations on the submatrices according to the decomposition structure.

摘要： In one embodiment, a device in a network identifies delay requirements of each of a plurality of media streams. The device selects a joint forward error correction (FEC) encoding strategy for the plurality of media streams based on the identified delay requirements of the streams and on a burst loss length of a communication channel. The device applies the selected joint FEC encoding strategy to the plurality of media streams, to form a multiplexed packet stream. The device sends the multiplexed packet stream to one or more nodes in the network via the communication channel.
