  • Patent number: 11844188
    Abstract: The described technology is generally directed towards a system and method to distribute available power to devices in a group. A group of devices, such as a rack of servers in a data center, can have a group power consumption limit, such as the limit of a power distribution unit that supplies power to the group. The group of devices can each report their individual power consumption to a manager, and the manager can combine the individual power consumptions. The manager can compare the combined power consumption of the group to the group power consumption limit to determine a power headroom. The manager can determine power consumption limits for the devices of the group based on the power headroom, the individual power consumptions, and device priority information.

  • Patent number: 11831585
    Abstract: A method and system for controlling a full-duplex communication system to operate as a time domain duplexing system with dynamic bandwidth allocation. One method includes detecting a change in conditions which necessitates an updated transmit time allocation and generating a LLDP advertisement which reflects the updated transmit time allocation. The initiating port transmits the LLDP advertisement to a link partner to notify the link partner of the updated transmit time allocation and in response, the initiating port receives a link partner LLDP advertisement from the link partner. The updated transmit time allocation is provided to a TCI client and the TCI client updates the reconciliation sublayer with updated transmit time allocation. Then implementing, using the reconciliation sublayer, transmit time allocations for a PHY layer and a MAC layer. Transmitting the data with the PHY layer occurs over a channel during transmit time allocations as defined by the reconciliation sublayer.

  • Patent number: 11825575
    Abstract: A PWM lighting bridge manages hardware PWM compensation components. One or more PWM outputs are driven based upon a master PWM input signal. The master PWM input signal is processed through a mapping function to produce a desired output signal(s) on the one or more PWM outputs. The mapping function comprises a set of compensation bins having a maxim input duty cycle, a minimum input duty cycle and an output duty cycle. The mapping process selects a bin based on determining whether the input duty cycle is within the minimum and maximum duty cycle ranges of the bins and then uses the specified output duty cycle for the one or more PWM outputs. The PWM lighting bridge provides configuration and runtime management of the hardware PWM compensation components. Read/write access to the PWM compensation bins provides customizable configurations of the input and output PWM characteristics.

  • Patent number: 11493978
    Abstract: Techniques for employing a decentralized sleep management service are described herein. In some instances, each computing device of a group of computing devices periodically shares information about itself with each other computing device of the group. With this information, each computing device within the group that is awake and capable of managing other devices selects a subset of devices to probe. The devices then probe this subset to determine whether the probed devices are asleep. In response to identifying a sleeping device, the probing device takes over management of the sleeping device. Managing the sleeping device involves informing other devices of the group that the sleeping device is being managed, in addition to monitoring requests for services on the sleeping device. In response to receiving a valid request for a service hosted by the sleeping device, the managing device awakens the sleeping device and ceases managing the now-woken device.

The provisioning system generates a first and second thread for validation of the first and second devices, respectively. Responsive to determining by the first thread that the first device is not validated, the provisioning system notifies a detection system that the validation of the first device has not passed. Responsive to determining by the second thread that the second device is validated, the provisioning system provisions the second device for integration with one or more provisioned devices on the network.

  • Patent number: 11249541
    Abstract: Systems, methods, and other embodiments associated with wake-on-frame mechanisms are described. According to one embodiment, an apparatus includes a central processing unit (CPU) that performs routing related processing on packets prior to sending the packets to one or more destination devices and a switch configured to send packets to the CPU. The switch is configured to, in response to receiving a new packet for the CPU, determine whether a wake-on-frame mechanism is enabled. When the wake-on-frame mechanism is enabled, the switch causes an interrupt signal to be sent to the CPU, such that receiving the interrupt signal will cause the CPU to wake up. When the wake-on-frame mechanism is disabled, the switch sends the packet to the CPU.

  • Patent number: 11212159
    Abstract: Novel tools and techniques might provide for implementing interconnection gateway and/or hub functionalities between two or more network functions virtualization (“NFV”) entities that are located in different networks. In some embodiments, a NFV interconnection gateway (“NFVIG”) might receive a set of network interconnection information from each of two or more sets of NFV entities, each set of NFV entities being located within a network separate from the networks in which the other sets of NFV entities are located. The NFVIG might be located in one of these networks. The NFVIG might abstract each set of network interconnection information, and might establish one or more links between the two or more sets of NFV entities, based at least in part on the abstracted sets of network interconnection information. The NFVIG might provide access to one or more virtualized network functions (“VNFs”) via the one or more links.

  • Patent number: 11144486
    Abstract: An information handling system includes a processor with an Improved Inter-Integrated Circuit (I3C) master interface, a first device with a first I3C slave interface, and a second device with a second I3C slave interface. The first I3C slave interface provides first In-Band Interrupts (IBIs) to the I3C master interface and has a first I3C address. The second I3C interface provides second IBIs to the I3C master interface and has a second I3C address. The second I3C address is higher than the first I3C address. The processor receives the first IBI, determines that the second IBIs are masked by the first Mb due to the second I3C address being higher than the first I3C address, and assigns a third I3C address to one of the first I3C slave interface and the second I3C slave interface in response to determining that the second IBIs are masked by the first IBIs.

  • Patent number: 11140025
    Abstract: Systems and techniques for mission critical (MC) push notification mechanism in a high-reliability (HR) information centric network (ICN) are described herein. For example, a node may test network links to other nodes to classify the other nodes into proximate nodes and non-proximate nodes based on a reception metric. The node may then elect a set of leader nodes from the proximate nodes. Here, the set of leader nodes are selected based on link quality between respective leader nodes and non-proximate nodes. The node may detect an MC event and create an ICN data packet that contains data from the MC event. The node may then transmit the ICN data packet to the set of leader nodes that then relay the ICN data packet to the non-proximate nodes.
