  • Patent number: 11956313
    Abstract: Techniques and systems described herein relate to shared storage systems across network devices to use unused storage space and provide backup and additional storage for devices as needed. The techniques and systems include determining availability data describing available storage locations and amounts on network devices, compiling such data at a network controller, and communicating the availability data to the network devices. The network devices then directly communicate with each other to store data remotely as needed.
    Type: Grant

  • Patent number: 11600989
    Abstract: Methods and systems include identifying an abnormal condition in a PFC circuit comprising an input configured to be coupled to a 3-phase power source and to receive input 3-phase power from the 3-phase power source, a bus having a plurality of bus lines, each bus line configured to be coupled to the input and to carry one phase of the input 3-phase power, a PFC leg including a contactor configured to selectively couple a capacitor bank included in the PFC leg to the bus. In response to identifying the abnormal condition, the contactor is controlled to decouple the capacitor bank from the bus, and after a reset button has been activated, the contactor is recoupled to the capacitor bank to resume operating the PFC leg to provide power factor correction to the input 3-phase power.

  • Patent number: 10574519
    Abstract: Detection and configuration of a logical channel may be provided. First, data traffic received on a plurality of ports of a first network device may be analyzed by a computing device. Next, based upon analyzing the data traffic received on the plurality of ports, the computing device may determine that the plurality of ports comprise a logical channel from the perspective of a second network device. The plurality of ports may then be configured as the logical channel on the first network device based upon determining that the plurality of ports comprise the logical channel from the perspective of the second network device.

  • Patent number: 8572217
    Abstract: Methods and apparatuses for providing clientless IP services for subscribers on a network interface that does not require either explicit client subnet configurations or explicit routes from the interface to the client subnets.

  • Patent number: 8122289
    Abstract: Compute resources of multiple resource cards are assigned to compute resource pools. Each compute resource pool is typically associated with a specific service (e.g., VoIP, video service, deep packet inspection, etc). Compute resource groups are created in each compute resource pool and are allocated one or more compute resources of that compute resource pool. Those compute resources in a given resource pool that are not allocated to a compute resource group are set as backup compute resources. Upon a failure of a compute resource in a compute resource pool that includes backup compute resources, a backup compute resource is selected and takes over the function of the failed compute resource. Upon a failure of a compute resource in a compute resource group of a compute resource pool that does not include a backup compute resource, the traffic is load balanced across the remaining compute resources of that compute resource group.
