  • Patent number: 11374834
    Abstract: A method and network device for network traffic flooding. Specifically, the method and network device disclosed herein implement the mitigation of the lack of data-link layer (or L2) addressing resolutions, usually learned by or programmed manually into the network device, through the flooding of affected network traffic across identified network broadcast domains. Flooding of the network traffic in the aforementioned manner may ensure that at least the destination(s) of the network traffic receives the network traffic at least in scenarios where which it is unknown out of which particular physical network interface(s) should the network traffic be transmitted to reach the destination(s).

  • Patent number: 11362950
    Abstract: An apparatus and method for classifying traffic data in a communication network based on IP flow. Traffic data in a communication network is monitored in order to detect an IP flow. A preliminary classification is assigned to the IP flow based on protocol information contained in its first packet. Subsequent packets within the IP flow are further monitored, and the IP flow is reclassified based, in part, on the domain name of the responding server. Web pages can also be classified, and monitored to determine their response time.

  • Patent number: 11343163
    Abstract: Each of multiple vehicle data collection devices are configured to collect data streams associated with operation of a vehicle. The data streams include time-stamped speed data. A transmitter is configured to transmit the data streams. An analytics server is configured to receive the data streams transmitted by the transmitter and to process the data. In connection with the processing, data streams with at least one common time stamp are identified. The time-stamped speed for one of the data streams at a first time interval is compared to the time-stamped speed for another of the identified plurality of data streams at a second time interval, where the second time interval comprises the first time interval plus an additional time increment. Based on the comparison, it is determined whether the two of the plurality of data streams are associated with a same trip or a different trip.

  • Patent number: 11337226
    Abstract: A user equipment, a method, and computer-readable media. The UE, which includes a transceiver with a plurality of antenna panels, is configured to determine a link quality of a serving antenna panel. If the link quality of the serving panel is below a quality threshold, resources are allocated from the serving antenna panel to another antenna panel during a sweeping period to identify one or more beams of a target antenna panel for resuming communications. Measurements for a set of beams of the other antenna panel are obtained, during the sweeping period, with the allocated resources. The other antenna panel can be determined to be the target antenna panel based on the obtained measurements. The UE can switch from the serving antenna panel to the target antenna panel, select the one or more beams based on the obtained measurements, and resume the communications on the selected one or more beams.

  • Patent number: 11284437
    Abstract: A device (e.g. a wireless communication device) may determine, according to a set of guidelines, a list that includes system information to be requested by the device as part of a system information request procedure. The device may determine whether to combine the system information request with an additional request associated with a random access procedure (RACH). In response to determining that the requests are to be combined, the device may initiate a unified RACH that combines the system information request and the additional request. The decision to combine the requests may be based on the type of the additional request, whether the list has been completed by the time the additional request is to be issued, and/or additional factors associated with wireless communications of the device. The system information request may be an OnDemand system information block request, and the RACH may be contention-based or contention-free.

  • Patent number: 11258685
    Abstract: A method of performing bidirectional forwarding detection (BFD) by a hardware forwarding element that includes a set of ingress pipelines and a set of egress pipelines. Each ingress pipeline includes a packet generator. A packet generator in a first pipeline periodically generates a pair of packets to monitor the health of a particular egress link. The pair includes a BFD transmit packet and a BFD dummy transmit packet. The method forwards each dummy BFD transmit packet to a first egress pipeline and increments a counter at the first egress pipeline. Each BFD packet is transmitted through the particular egress link to a network node. BFD packets received from the network node are forwarded to the first egress pipeline and the value of the counter is rest. The method marks the particular egress link as failed when the value of the counter exceeds a predetermined threshold.
