  • Patent number: 12009979
    Abstract: Systems and methods are provided for zero-touch provisioning of devices, such as sensors, on a network. When a device is unable/cannot access a network via Ethernet, cellular, or near field communications capabilities resident on the device, the device can alternatively be provisioned via an intermediate network device, such as an access point using, e.g., Device Provisioning Protocol or Wi-Fi EasyConnect. A cloud-based network management system may receive a device's bootstrapping information during or after manufacturing of the device. Ultimately, the device, via the intermediate network device, is able to communicate with a back-end, cloud-based network insight system from which configuration parameters for the device may be obtained.

  • Patent number: 12010211
    Abstract: Systems and methods are provided for encrypting data in a memristor array. The data may be scrambled by multiplying an input data unit by another data unit, by multiplying each element of a first data unit by a different instance of a second data unit. The process continues until all elements of the first data unit are multiplied by a different instance of the second data unit. The elements of the data units may be represented by resistive values of a memristor array. The result of all of the above multiplication of different instances of the second data unit are a new set of data units. All of the resulting data units are added together by adding the currents associated with values of the memristors representing the resulting data units. The operation may be performed as a finite field computation, with the memristor array.

  • Patent number: 12008444
    Abstract: Examples include detection of unclassified traffic in a network. Some examples use an unsupervised machine learning mechanism for generating a first set of clusters of a first set of samples associated with a first set of time intervals, based at least in part on network traffic over a network, in a first predetermined period of time. Each sample associated with the respective time interval includes distribution of packets based on their packet lengths. In response to retrieving a second set of samples associated with a second set of time intervals, based at least in part on network traffic, a second set of clusters of the second set of samples is generated. It is determined whether one or more features of the second set of clusters vary as compared to one or more features of the first set of clusters of the first set of samples to detect unclassified traffic in the second set of samples.

  • Patent number: 12003279
    Abstract: Examples described herein relate to a method and a system for removing the common-mode current. The receiver includes a photodetector, a common-mode adjustment circuit, an analog front-end, an eye scan circuit, and a control unit. The photodetector generates an input photocurrent responsive to a received optical signal. The common-mode adjustment circuit generates an adjusted input current based on the input photocurrent. The analog front-end generates a differential voltage based on the adjusted input current. Based on the differential voltage, the eye scan circuit generates an eye scan information defining a first outer eye and a second outer eye in an eye diagram. The control unit tunes the common-mode adjustment circuit based on a relative height metric of a first height of the first outer eye and a second height of the second outer eye to remove a portion of the common-mode current from the input photocurrent.

  • Patent number: 12001835
    Abstract: A system for performing in-service software upgrade on a network device is provided. In response to a software-upgrade command, the system generates an upgrade database based on a state database storing both a data-plane state and a control-plane state associated with the network device. The network device is managed by a management unit comprising a data-plane-management sub-unit and a control-plane sub-unit, and the upgrade database stores at least the data-plane state to allow the data-plane-management sub-unit to operate based on the upgrade database. The system separately upgrades the data-plane-management sub-unit and the control-plane sub-unit, without interrupting services provided by the network device. The system monitors the state database and the upgrade database to detect an event associated with the network device. In response to determining a triggering condition being met, the system performs an action to prevent a network outage or error.

  • Patent number: 11995043
    Abstract: A map-reduce compatible distributed file system that consists of successive component layers that each provide the basis on which the next layer is built provides transactional read-write-update semantics with file chunk replication and huge file-create rates. Containers provide the fundamental basis for data replication, relocation, and transactional updates. A container location database allows containers to be found among all file servers, as well as defining precedence among replicas of containers to organize transactional updates of container contents. Volumes facilitate control of data placement, creation of snapshots and mirrors, and retention of a variety of control and policy information. Also addressed is the use of distributed transactions in a map-reduce system; the use of local and distributed snapshots; replication, including techniques for reconciling the divergence of replicated data after a crash; and mirroring.
