  • Patent number: 10924253
    Abstract: In one embodiment, a method receives a downstream signal and an upstream signal in a same frequency band. The downstream signal and the upstream signal are separated into a first path and a second path. The downstream signal using the first path and the upstream signal using the second path are amplified in an analog domain. The method isolates the downstream signal and the upstream signal from one another and sends the downstream signal downstream to a subscriber device and sends the upstream signal towards a full duplex node.

  • Publication number: 20200037189
    Abstract: In some embodiments, a method sets a threshold over a frequency spectrum and receives a set of measurements that measures interference between a set of network devices over the frequency spectrum. A set of metric values based on the set of measurements is compared to the threshold at a plurality of points over the frequency spectrum. The method then selects whether the set of network devices are in a group that interfere with communications of each other based on the comparing.

  • Patent number: 10447398
    Abstract: In one embodiment, a method analyzes a size of a grant included in an upstream transmission from the device using a radio frequency over an optical network. When the size of the grant is less than a threshold, scheduling the upstream transmission on a first type of channel. The first type of channel includes characteristics of transmission such that an optical transmitter of an optical networking unit that receives the upstream transmission from the device will turn on when transmitting the upstream transmission via the optical network. When the size of the grant is greater than the threshold, scheduling the upstream transmission on a second type of channel. The size of the grant is such that the optical transmitter that receives the upstream transmission from the device is predicted to turn on when transmitting the upstream transmission via the optical network.

  • Patent number: 10129171
    Abstract: A Time and Frequency Division (TaFD) scheduler based on a TaFD allocation unit based credit allocation may schedule both time and frequency division for both legacy Data Over Cable Service Interface Specification (DOCSIS) channels and DOCSIS orthogonal frequency division multiple access (OFDMA) channels. In embodiments, scheduling by the TaFD schedules both single carrier quadrature amplitude modulation (SC-QAM) transmissions and OFDMA upstream transmissions. In embodiments, the scheduler schedules based on TaFD allocation unit based credit allocations, where TaFD allocation unit based credits may be allocated for OFDMA overlapped regions. The credits may be dynamically adjusted based on channel utilization and an outstanding bandwidth demand or a prioritized pending bandwidth demand. The TaFD scheduler may use independent hierarchy priority queuing schemes.

  • Patent number: 9787398
    Abstract: An OBI manager provides the reduction/elimination of optical beat interference (OBI). As will be described in more detail below, the OBI manager identifies OBI partners through an identification process performed via an RFoG network. An OBI partner may be two optical networking units (ONUs) that may interfere with one another when transmitting in the same time slot. Once the OBI partners are identified, the OBI manager may perform a mitigation process to mitigate possible OBI. For example, the OBI manager may organize the OBI partners to reduce OBI, such as by guaranteeing no OBI partners transmit at the same time.

  • Patent number: 9647786
    Abstract: With the introduction of orthogonal frequency division multiplexing (OFDM) technology in to communication channels in a cable network, cable modems that receive data downstream over subcarriers of the OFDM channel are grouped in to modulation tiers based on at least one metric. A profile is generated for each OFDM channel based on the measurements across cable modems and subcarriers related to the OFDM channel, including the metric values used to group the cable modems in to the modulation tiers. Included in an OFDM profile may be a scheme for allocating marginal cable modems in to the plurality of modulation tiers. The methods and systems for generating modulation and coding scheme profiles enable more efficient modulation by network elements.

  • Patent number: 9647801
    Abstract: With the introduction of orthogonal frequency division multiplexing (OFDM) technology to communication channels in a cable network, cable modems that receive data downstream over subcarriers of the OFDM channel are grouped into modulation tiers based on at least one metric. Modulation tiers are generated at a subcarrier group level such that network elements can use different profile tiers depending in the subcarrier group in use. A scheduler facilitates the scheduling of modulation tiers for network element destination groups across subcarrier groups, where the modulation tier for a network element may vary between subcarrier groups. The scheduler also facilitates scheduling multiple network element destination groups for transmission of a plurality of subcarrier groups for optimal transmission to the network elements.

  • Patent number: 9596152
    Abstract: Methods, systems, and computer readable media can be operable to determine impulse noise over a wide spectrum based upon measurements of impulse noise associated with each of a plurality of channels. Impulse noise can be observed on each of the plurality of channels and the observed impulse noise signals can be summed together. In summing observed impulse noise signals, a Fourier transform can be used to convert the observed impulse noises from a time domain representation to a frequency domain representation. The sum of the impulse noises can represent the impulse noise existing on the wide spectrum and can be converted from a frequency domain representation to a time domain representation using an inverse Fourier transform.

  • Patent number: 9596210
    Abstract: Methods, systems, and apparatus used to provide duplicate address detection in edge devices. Edge devices can include CMTS devices or DSLAMs where network nodes are not allowed to communicate with each other directly. Duplicate address detection proxies can provide duplicate address protection for network devices and can avoid the issue of broadcasting node advertisement messages to all of the devices connected to a particular downstream link.

  • Patent number: 9363202
    Abstract: Systems, methods and computer readable media for providing low-latency scheduling on upstream channels. Systems and methods can include a low-latency scheduler and a network interface. The low-latency scheduler can assign a first group of upstream channels for standard communication of packets on a network, and to assign a second group of upstream channels for communication of small upstream packets on the network. The network interface can communicate transmission opportunities identified by the low-latency scheduler to the subscriber devices. The transmission opportunities for subscriber devices are assigned such that devices with a threshold amount of traffic receive transmission opportunities in the first group of upstream channels, and subscriber devices with less than the threshold amount of traffic receive transmission opportunities in the second group of upstream channels.

  • Patent number: 9203767
    Abstract: Bandwidth is assigned to subscribers of a data network by applying logic of one or more network devices to sample bits of information communicated over a network communication medium to identify if there is a network congestion condition or an extremely lightly loaded condition. The maximum bandwidth assigned to a subscriber is below a normative maximum bandwidth assigned to the subscriber if the network is congested and the logic of the one or more network devices identifies the subscriber as a heavy bandwidth user. The maximum bandwidth assigned to a subscriber is above the normative maximum bandwidth if the network is extremely lightly loaded and the subscriber is a heavy bandwidth user.

  • Patent number: 9160576
    Abstract: Methods, systems, and computer readable media can be operable to conditionally use feedback equalization during equalization of a signal. In embodiments, a feedback component of a receiver can be turned off during initial ranging and periodic maintenance intervals, and resulting pre-equalization coefficients can be used to pre-distort subsequent data signals at a transmitter.
