  • Patent number: 11838105
    Abstract: This disclosure describes digitally generating sub-carriers (SCs) to provide isolation and dynamic allocation of bandwidth between uplink and downlink traffic between transceivers that are communicatively coupled via a bidirectional link including one or more segments of optical fiber. Separate uplink and downlink communication channels may be created using digitally generated SCs and using the same transmitter laser. In some implementations, one or more of the nodes include a transceiver having at least one laser and one digital signal processing (DSP) operable for digitally generating at least two SCs and detecting at least two SCs. The transceiver can transmit selected SCs, and can receive other SCs. Accordingly, the transceiver can facilitate bidirectional communication, for example, over a single optical fiber link. In some instances, techniques can facilitate dynamic bandwidth assignment by facilitating adding or blocking of optical subcarriers from transmission in an uplink or downlink direction.

  • Patent number: 11194630
    Abstract: Shuffling of into partitions by first grouping input vertices of a limited number. Each group of input vertices may then be simply shuffled into a corresponding group of intermediate vertices, such as by broadcasting. A second grouping occurs in which the intermediate vertices are grouped by partition. The intermediate vertices then shuffle into corresponding output vertices for the respective partitions of that group. If the intermediate vertices are still too large, then this shuffling may involve recursively performing the shuffling just described, until ultimately the number of intermediate vertices shuffling into the output vertices is likewise limited. Thus, the final shuffling into the output vertices might also be simply performed by broadcasting.

  • Patent number: 10454587
    Abstract: Parallel optical transponders with an optical comb source, and methods of using the same, are provided. The optical comb source can provide multiple optical carriers from a single source. The multiple optical carriers can be phase-aligned, which can allow joint processing of a received signal. The multiple optical carriers can also allow for modulating a demultiplexed data signal using multiple modulators rather than modulating the entire data signal using a single modulator.

  • Patent number: 10452446
    Abstract: Transparently executing applications among cores in a multi-processor system includes monitoring elements associated with each processor which align execution of threads within corresponding cores of the processors. Alignment is accomplished by monitoring system resource utilization by each core, comparing process counters associated with corresponding cores, and comparing data sets in and out during application frame switching. In a further aspect, inputs are coordinated by a synchronization element. Likewise, outputs for corresponding cores are compared to ensure no corrupted data is propagated.

  • Patent number: 10447588
    Abstract: A decentralized Integrated Modular Avionics (IMA) architecture configured for onboard avionics processing eliminates centralized computing cabinets and distributes avionics processing capabilities to a network of smart switching devices positioned throughout the aircraft, each smart switch including a multicore processing environment (MCPE) for generalized application hosting in addition to the switching elements. The smart switching network can be scaled up or down for smaller or larger aircraft, or organically grown by adding more processing components. Additional real-time multicore processors may be located in smart remote data concentrators (RDC) for handling I/O and routing of network data between external remote units and aircraft systems and the hosted applications on the smart switches. The real-time environments executing on the smart RDCs may be reserved for low-latency closed-loop functions, or may host additional general-purpose avionics processing.

  • Patent number: 10397674
    Abstract: Methods, systems, and apparatus for Passive Optical Network (PON) wavelength bonding are disclosed. In one aspect, a first frame of data to a first optical network unit (ONU) is transmitted by an optical line terminal (OLT) over a first wavelength. While the first frame of data is being transmitted to the first ONU over the first wavelength, a first portion of a second frame of data to a second ONU is transmitted by the OLT over a second wavelength. After transmission of the first frame of data over the first wavelength has completed and while the first portion of the second frame of data is still being transmitted to the second ONU over the second wavelength, a second portion of the second frame of data to the second ONU is transmitted by the OLT over the first wavelength.

  • Patent number: 10256935
    Abstract: A disclosed method for optimizing channel selection in a flexible grid of an optical network may be used to select a minimum number of channels to allocate to traffic between pairs of optical transponders at a particular distance based on the modulation format and the FEC mechanism used. The method may include selecting an initial number of channels to allocate to the traffic, tuning the modulation format for the traffic while potentially reducing the number of channels, and tuning the FEC mechanism for the traffic while potentially further reducing the number of channels. The transponders may support multiple modulation formats of different orders and an adaptive FEC mechanism for which the maximum number of FEC overhead bytes is equal to the number of bytes in the transmitted data packets. The method may be implemented by an SDN controller and may be dependent on a feedback mechanism between the optical transponders.
