    Abstract: A dynamic rebalancer operates in a server cluster independently of routers directing traffic to the servers in the cluster. An analysis component uses configuration information and statistics information to determine which session, if any, should be moved. A filter component receives transfer instructions from the analysis component. When the filter component receives transfer instructions from the analysis component, the filter component adds a redirect command to the client request. The filter component continually redirects client requests within the session to the new server until the client receives the redirect command and begins to send client requests to the new server.

  • Patent number: 11197167
    Abstract: Compensation is provided for foreign interference within a cell. Uplink (UL) noise on an UL channel to a first base station (BS) device is detected. Whether the UL noise includes interference is determined. Interference can include any device other than a mobile device configured to communicate with a BS device associated with a cell. The first service area of the BS device can be modified, e.g., scaled based on determining that the UL noise includes interference. Scaling can include reducing the first service area to a second service area that does not include an imbalance region in the first service area caused by the foreign interference. Scaling can be effected by reducing the amount of downlink power from the first BS device, or by adjusting a re-selection parameter associated with reducing the range of the BS device.

  • Patent number: 11115975
    Abstract: In a wireless communication method, base stations having an identical number of channels for receiving narrowband modulation (UNB) are divided into groups. Data transmission channels of all base stations have identical time and frequency characteristics. All subscribers split into groups are periodically sent messages with subscriber group numbers by all the base stations. When a group number of a corresponding subscriber coincides with a group number in a message received by the subscriber, all the subscribers of the group send response messages to the base stations using UNB, wherein response messages are sent sequentially from all subgroups of subscribers of the group, and subscribers of a subgroup send response messages on different frequencies. The base stations receive the response messages on all frequencies corresponding to subscribers, decode the messages and generate a database of response messages, which can be used for generating subsequent messages with corresponding subscriber group numbers.

  • Patent number: 10116375
    Abstract: A procedure to establish a link in a directional wireless system where two nodes cannot listen to each other unless optimized beamforming pair is used and timing and framing synchronization is acquired. The procedure determines a set of beamforming pairs that the nodes can use for communication in addition to acquiring the framing and timing synchronization. Training packets are periodically transmitted by a transmitter while a receiver listens in each of a number of receive directions. Training packets are sent N times in N directions while a receiver listens in each of M receive directions until all N×M possible transmit and receive direction pair possibilities are tried. The receiver informs the transmitter which transmit and receive direction pairs were successful in creating communication links between the nodes.

    Abstract: Novel tools and techniques are provided for delivering plain old telephone service (“POTS”) telephony over high speed data networks. In particular, various embodiments provide tools and techniques for concurrent transmission of POTS voice signals and data signals over the same wire(s) of high-speed data lines or data cables. Various systems and methods might, in some instances, utilize upbanding or rebanding of the POTS voice band to a higher frequency band above the data stream band spectrum for transport of voice concurrent with data over the same wire(s) in the cable. The system might comprise interface devices at either end of a cable segment, one interface device to reband the voice signal and to combine the voice signal with the data signal for each dual-transport wire in the cable, and another interface device at the other end to separate the voice signal from the data signal.

  • Patent number: 9871613
    Abstract: We disclose an optical add-drop multiplexer that can apply different routing operations to different subcarriers of a data frame. In an example embodiment, the digital signal processor (DSP) of the optical add-drop multiplexer carries out subcarrier-specific add, drop, and pass-through operations in the electrical frequency domain, which enables the DSP to only partially unwrap the pass-through subcarriers, thereby at least partially avoiding some of the more processing-power-hungry DSP operations and reducing the sub-wavelength routing latency accordingly. Also disclosed is an example data-frame structure that can be used to provide subcarrier-specific routing instructions to the optical add-drop multiplexer.
