  • Patent number: 11153336
    Abstract: A method and system for detecting malicious behavior from smart appliances within a network. Smart appliances have a certain level of intelligence that allows them to perform a specific role more effectively and conveniently. Network traffic data and identification data is collected about smart appliances within a network. The data is sent to a behavior analysis engine, which computes confidence levels for anomalies within the network traffic that may be caused by malicious behavior. If the behavior analysis engine determines that malicious behavior is present in the network, it sends an instruction to a network traffic hub to block network traffic relating to the anomaly. In some embodiments, network traffic is blocked based on source-destination pairs. In some embodiments, network traffic is blocked from a device outside the network that is determined to be malicious.

  • Patent number: 11115453
    Abstract: Features relating to communicating delay information and minimizing aggregate processing delays corresponding to content streams, e.g., audio and video streams, in a multi-media communication session while still achieving stream synchronization, are described. Some embodiments are well suited for systems where video and audio streams are transcoded by different entities. In some embodiments downstream entities, e.g., transcoder and/or receiving end device, are informed about the delay introduced to at least one stream by one or more upstream devices, e.g., a transcoder. The downstream entity synchronizes the received content streams by adding artificial latency as needed to the relevant one of the streams based on the received delay information thereby avoiding unnecessary introduction of artificial delays at every transcoding node in the path.

  • Patent number: 10916252
    Abstract: Systems and methods relying on recognition of a pattern in a data stream, such as detecting a hotword in an audio data stream are sensitive to latency (e.g., response time). To reduce power consumption, a low power processor may be used in combination with a higher power speech recognition device. When the hotword is detected by the low power signal processor, the primary speech recognition device is signaled to wake up and begin emptying a buffer storing the hotword and subsequent audio data. Latency is the delay incurred to recognize the hotword and begin emptying the buffer. To catch-up and reduce the latency, the buffer is drained at a faster rate than the buffer is filled until a latency reduction trigger is received. The latency reduction trigger is generated when the latency has been reduced to a predetermined level.

  • Patent number: 10868769
    Abstract: To more efficiently utilize buffer resources, schedulers within a traffic manager may generate and queue read instructions for reading buffered portions of data units that are ready to be sent to the egress blocks. The traffic manager may be configured to select a read instruction for a given buffer bank from the read instruction queues based on a scoring mechanism or other selection logic. To avoid sending too much data to an egress block during a given time slot, once a data unit portion has been read from the buffer, it may be temporarily stored in a shallow read data cache. Alternatively, a single, non-bank specific controller may determine all of the read instructions and write operations that should be executed in a given time slot. The read instruction queue architecture may be duplicated for link memories and other memories in addition to the buffer memory.

    Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing a control channel (PDCCH) design. The PDCCH can occupy an initial number of OFDM symbols of a downlink subframe, while occupying less than the full system bandwidth. The PDCCH can be time division multiplexed (TDM) with a shared channel (PDSCH) or frequency division multiplexed (FDM) with a PDSCH. The PDCCH can further be multiplexed with another PDCCH in a contiguous or non-contiguous region. Resources allocated to the PDCCH can overlap or partially overlap resources allocated to the PDSCH. An Evolved Node-B (eNB) can provide configuration information for the PDCCH design in Radio Resource Control (RRC) signaling to a user equipment (UE), or through use of a Master Information Block (MIB) or System Information Block (SIB).

  • Patent number: 10841192
    Abstract: Systems and techniques are described for calculating performance improvement achieved and/or expected to be achieved by optimizing a network connection. Network characteristics can be measured for non-optimized network connections. Next, the network characteristics can be analyzed to obtain a set of non-optimized connection groups, wherein each non-optimized connection group corresponds to non-optimized network connections that have similar network characteristics. Network characteristics for an optimized network connection can be measured. Next, a non-optimized connection group can be identified based on the network characteristics that were measured for the optimized network connection. A performance improvement metric can then be calculated based on a throughput of the optimized network connection and corresponding throughputs of non-optimized network connections in the identified non-optimized connection group.

  • Patent number: 10796232
    Abstract: Methods for analyzing and rendering business intelligence data allow for efficient scalability as datasets grow in size. Human intervention is minimized by augmented decision making ability in selecting what aspects of large datasets should be focused on to drive key business outcomes. Variable value combinations that are predominant drivers of key observations are automatically determined from several competing variable value combinations. The identified variable value combinations can then be then used to predict future trends underlying the business intelligence data. In another embodiment, an observed outcome is decomposed into multiple contributing drivers and the impact of each of the contributing drivers can be analyzed and numerically quantified—as a static snapshot or as a time-varying evolution.

  • Patent number: 10798614
    Abstract: A traffic controller (8) receives, from a traffic monitor (7), a first control message generated in response to an increase in a total transmission rate of a plurality of packet flows sent from a plurality of wireless terminals (1) to a specific external network. The controller (8) determines, based on an evaluation criterion received from a criteria manager (6), one or more packet flows on which traffic shaping is to be imposed. In response to the first control message, the controller (8) controls a base station within a RAN (2) or a packet transfer node within a mobile backhaul (30) to execute the traffic shaping. This, for example, contribute to adjusting traffic that passes through a cellular communication network based on a monitoring result of a total transmission rate of traffic sent from the cellular communication network to the external network.

  • Patent number: 10785300
    Abstract: An I/O management method includes determining local target I/O rates for a plurality of storage controllers across which an I/O stream is distributed. The local target I/O rates may reflect a target latency corresponding to a QoS attribute associated with the I/O stream. A cumulative target I/O rate may be determined based on the local target I/O rates. A token bucket rate may be calculated for each applicable storage controller based on the local target I/O rates. The storage controllers may implement token bucket algorithms in accordance with the token bucket rates to enforce the QoS for the I/O stream. The local target I/O rates may be determined periodically based on measured data indicating actual latency and traffic. A queue depth is determined based on the measured values of latency and traffic. The queue depth is then used with the desired value of latency to obtain the target I/O rates.

  • Patent number: 10778613
    Abstract: Methods and systems for managing packet flow in a local network in a manner that allows network devices at the edge of the network to use minimal buffer memory while maximizing use of bandwidth allocated on an interconnect between the local network and an external network. Packet flows facing external network problems are scaled back, reducing redundant traffic on the interconnect and allowing for use of small buffers in edge devices. A flow source marks a subset of packets within a flow for preferential treatment within the local network. The flow source then adjusts the flow rate only responsive to failures in transmission of the marked packets. In some implementations, an edge device removes the markings prior to packet egress. The local network honors the preferential treatment markings such that a loss of a marked packet is more likely to occur on an external network than on the local network.

  • Patent number: 10771405
    Abstract: A source access network device multicasts copies of a packet to multiple core switches, for switching to a same target access network device. The core switches are selected for the multicast based on a load balancing algorithm managed by a central controller. The target access network device receives at least one of the copies of the packet and generates at least metric indicative of a level of traffic congestion at the core switches and feeds back information regarding the recorded at least one metric to the controller. The controller adjusts the load balancing algorithm based on the fed back information for selection of core switches for a subsequent data flow.
