Patent number: 9363202Abstract: 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.Type: GrantFiled: November 5, 2012Date of Patent: June 7, 2016Assignee: ARRIS Enterprises, Inc.Inventor: Ayham Al-Banna

Patent number: 9203767Abstract: 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.Type: GrantFiled: June 11, 2014Date of Patent: December 1, 2015Assignee: ARRIS Enterprises, Inc.Inventors: Ayham Al-Banna, Carol Ansley, Thomas J Cloonan, Jeffrey J Howe

Publication number: 20150280816Abstract: 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.Type: ApplicationFiled: April 25, 2014Publication date: October 1, 2015Applicant: ARRIS Enterprises, Inc.Inventors: Ayham Al-Banna, Lawrence C.

Publication number: 20150256420Abstract: 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.Type: ApplicationFiled: March 7, 2014Publication date: September 10, 2015Applicant: ARRIS Enterprises, Inc.Inventor: Ayham Al-banna

Publication number: 20150188653Abstract: 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.Type: ApplicationFiled: December 27, 2013Publication date: July 2, 2015Applicant: ARRIS Enterprises, Inc.Inventors: William T. Hanks, Jeffrey J. Howe, Ayham Al-Banna

Publication number: 20150188668Abstract: 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.Type: ApplicationFiled: December 27, 2013Publication date: July 2, 2015Applicant: ARRIS Enterprises, Inc.Inventor: Ayham Al-banna

Patent number: 9065735Abstract: Methods, systems, and computer readable media can be operable to calculate modulation error ratio using feedback from error correction processing. An error correction value obtained through an error correction process can be added to a measured slicer error in order to calculate a modulation error ratio. An error correction value associated with a correctable error can be based upon the difference between a received symbol and a correct symbol. An error correction value associated with an uncorrectable error can be based upon a measured slicer error and the distance between constellation symbols in a constellation diagram.Type: GrantFiled: April 9, 2014Date of Patent: June 23, 2015Assignee: ARRIS Enterprises, Inc.Inventors: Carl L.

Patent number: 8910227Abstract: A method performed by a central network device, such as a network edge device, or a CMTS, determines whether some of a plurality of user devices coupled to a communication device are transmitting at substantially their respective maximum power output level over a given channel. If the central device determines that some of the devices are operating at near their maximum output level (“power pegged,) the central device searches for another channel that can carry the traffic of the power pegged devices at reduced data rate. If another channel can accommodate transmission of signals of the power pegged device, the central device instructs the power pegged devices to tune to the new channel at a reduced data rate compared to the data rate of the current channel.Type: GrantFiled: September 30, 2013Date of Patent: December 9, 2014Assignee: ARRIS Enterprises, Inc.Inventors: Ayham Al-Banna, Thomas Cloonan
