  • Patent number: 10237875
    Abstract: Technology is described for managing network traffic directed to a plurality of destination internet protocol (IP) addresses that are served by a destination host or service. A network action communication for a destination IP address served by the destination host or service may be received. The destination host or service may be overloaded when a number of network action communications directed to the plurality of destination IP addresses served by the destination host or service exceeds a defined threshold. The network action communications may be dropped in order to prevent the destination host or service from receiving a volume of network traffic that exceeds the defined threshold.

  • Patent number: 10230636
    Abstract: Network hardware devices organized in a wireless mesh network (WMN) in which one network hardware devices includes a first radio and a second radio coupled to a processing device.

The processing device access a master routing table to determine that the second radio is to forward the request and forwards the request to the second radio. The second radio accesses a local routing table at the second radio to determine that a radio of a third mesh network device is a next-hop mesh network device in a first path to the second mesh network device. The second radio sends the request to the radio of the third mesh network device.

  • Patent number: 10219292
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may employ a multiplexing configuration based on latency and efficiency considerations. The base station may transmit a resource grant, a signal indicating the length of a downlink (DL) transmission time interval (TTI), and a signal indicating the length of a subsequent uplink (UL) TTI to one or more user equipment (UEs). The base station may dynamically select a new multiplexing configuration by, for example, setting the length of an UL TTI to zero or assigning multiple UEs resources in the same DL TTI. Latency may also be reduced by employing block feedback, such as block hybrid automatic repeat request (HARQ) feedback. A UE may determine and transmit HARQ feedback for each transport block (TB) of a set of TBs, which may be based on a time duration of a downlink TTI.

  • Patent number: 10218523
    Abstract: For a managed network implementing at least one logical router having centralized and distributed components, some embodiments provide a method for configuring a managed forwarding element (MFE) executing on a first host machine to implement a distributed multicast logical router and multiple logical switches logically connected to the logical router in conjunction with a set of additional MFEs executing on additional host machines to process multicast data messages. The method receives a multicast group report from a data compute node (DCN) that executes on the first host, sends a summarized multicast group report indicating multicast groups joined by DCNs executing on the first host to a set of central controllers, receives data based on an aggregated multicast group report from the set of central controllers, and uses the data based on the aggregated multicast group report to configure the MFE to implement the distributed multicast logical router.

  • Patent number: 10201000
    Abstract: Disclosed are apparatus and methods of adaptive frequency channel allocation adjustment to mitigate the in-device interference of simultaneous coexistence operation of multiple radio frequency operation. At least one of channel conflict tables is pre-defined in the device memory. One of the multiple radio frequency operation is prioritized, and the mobile device would request the cellular base transceiver station or the host access point to allocate a non-conflicted frequency channel with respect to the prioritized radio frequency channel. Once the prioritized communication channel changes due to handover or any other reason, the device would check the allocated channels against the pre-defined conflict channel tables and request the access point or the base station to adjust the secondary frequency channel if there exists the conflict channel.

  • Patent number: 10200300
    Abstract: A network device in a Named Data Networking (NDN) network receives an Interest from a consumer including a name and an Expected Data Size of data requested through the Interest. The network device forwards the Interest along a path to a producer of the data based on the name. As a result, the network device receives data that has traversed the path in reverse and satisfies the forwarded Interest. The network device determines an actual data size of the received data. The network device compares the actual data size to the Expected Data Size. If the actual data size is greater than the expected data size, and if a level of traffic congestion associated with forwarding the received data to the consumer is below a threshold, forwarding the received data to the consumer along a path based on the name of the data.

  • Patent number: 10194429
    Abstract: In a mobile station that performs communication with a base station device via a plurality of cells, the plurality of cells are grouped into a first group constituted by cells having an uplink transmission timing that is the same as that of one primary cell and a second group constituted by one or more cells having an uplink transmission timing that is different from that of the primary cell. The uplink transmission timings are each managed using a corresponding transmission timing timer for each of the groups. In a case where a transmission timing timer for the first group has expired, the mobile station stops all uplink transmissions in the plurality of cells. In a case where a transmission timing timer for the second group has expired, the mobile station stops uplink transmissions in the cells constituting the second group for which the transmission timing timer has expired.

  • Patent number: 10193812
    Abstract: In general, techniques are described for load-balancing responsibility for forwarding of multicast traffic into an active-active Ethernet segment between two or more multi-homed provider edge (PE) routers in an Ethernet Virtual Private Network (EVPN). In one example, a PE router may receive an Internet Group Management Protocol (IGMP) join report for a multicast group. The PE router may send join synch routes used to synchronize the join report for the multicast group across the Ethernet segment. The PE router may deterministically determine whether the PE router is configured to be an elected multicast forwarder for one of a plurality of multicast groups. If the PE router is elected a multicast forwarder, the PE router may configure a forwarding state of the PE router to ignore a designated forwarder calculation and to forward the multicast traffic into the Ethernet segment regardless of whether the PE router is a designated forwarder.

  • Patent number: 10193599
    Abstract: The inventive concept relates to a distributed antenna system (DAS), and more particularly, to an uplink signal transmission operation of each of node units constituting a DAS. A node unit of a DAS includes a multiplexer configured to generate a single uplink signal by selectively outputting any one of m uplink signals received from m lower node units at an interval of a predetermined output time, where m is a positive integer greater than 1, and a down-sampler configured to output a transmission uplink signal by converting a sampling rate of the single uplink signal to correspond to a sampling rate of any one of the m uplink signals. Accordingly, it is possible to provide a DAS capable of processing and outputting, as one signal, uplink signals received from a plurality of remote units, without any error.

  • Patent number: 10182431
    Abstract: Embodiments of the present invention provide a method and apparatus for triggering aperiodic feedback in coordinated multipoint transmission. The method includes: transmitting, by an eNB to UE, dynamic control information (DCI) and preconfigured feedback sets corresponding to the DCI, so that the UE aperiodically feeds back corresponding channel state information (CSI) according to the DCI and the feedback sets corresponding to the DCI; wherein the preconfigured feedback sets corresponding to the DCI are classified according to a triggered transmitting point or a CSI-RS of non-zero power, or are classified according to configured CSI, or are classified according to an interference type. With the method and apparatus of the embodiments of the present invention, a relatively good tradeoff between flexibility of aperiodic CSI feedback and signaling load in a CoMP transmission process or a joint transmission process of CoMP and CA may be achieved.
