  • Patent number: 11799716
    Abstract: Techniques are described to provide layer 2 (L2) circuit failover in the event connectivity to an Ethernet Virtual Private Network (EVPN) instance is lost. For example, if one of multi-homed provider edge (PE) devices loses connectivity to the EVPN instance, the PE device may mark its customer-facing interface as down and propagate the interface status to the access node such that the access node may update its routing information to switch L2 circuits to another one of the multi-homed PE devices having reachability to the EVPN instance. In some examples, the plurality of PE devices may further implement Connectivity Fault Management (CFM) techniques to propagate the interface status to the access node such that the access node may update its forwarding information to send traffic on a different L2 circuit to another one of the multi-homed PE devices having reachability to the EVPN instance.

  • Patent number: 11792067
    Abstract: This application provides an isolation and recovery method and related network device for a case when one or more physical layer apparatuses (PHYs) in a flexible Ethernet group (FlexE group) are faulty. In the method, if a network device determines that a first overhead block corresponding to each current available PHY is stored in a corresponding memory, the network device determines that a FlexE group meets a PHY alignment condition, and starts to simultaneously read cached data from all memories. Therefore, there is no need to insert local fault LF code blocks to all clients, and there is no need to recreate a group. This effectively reduces the impact of a faulty PHY on client services carried by a normal PHY.

  • Patent number: 11747885
    Abstract: Disclosed are techniques for saving power in a Universal Serial Bus (USB) repeater/re-timer between a USB host and a peripheral device by intercepting packets received from the host to predict the direction of data traffic to selectively turn off/on circuitry of a peripheral port used to receive packets from the peripheral device. If a host port determines that the host is sending a start-of-frame (SOF) packet, the direction of data flow is from the host to the peripheral device, and the repeater may turn off the peripheral port such as squelch circuitry. If the host port determines that the host is sending a non-SOF packet, such as an address token that precedes a host-to-peripheral-device data transfer or a peripheral-device-to-host data transfer, the direction of data flow is anticipated to be from the peripheral device to the host, and the repeater may re-enable the deactivated circuitry of the peripheral port.

  • Patent number: 11751113
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may autonomously initiate a handover procedure and select a target base station for the handover procedure. The UE may measure a signal from the source base station or the target base station, or both, and the UE may determine whether specific criteria at both base stations are within a pre-configured range. If the criteria at both base stations are within the pre-configured range, the UE may identify the target base station as a potential candidate for a handover. Accordingly, when the UE determines that radio conditions with the source base station are deteriorating (or fall below a threshold), the UE may initiate a handover to the target base station autonomously and without specific direction from the source base station.

  • Patent number: 11743393
    Abstract: The disclosed system identifies and resolves telecommunication network problems and/or problems with devices utilizing the network. The system segments the user devices into groups having similar characteristics, by grouping together devices more likely to leave the network, and devices less likely to leave the network. Each group of devices has a trained machine learning model, to predict the NEX score for each device. The system focuses on devices with a low NEX score. The system determines whether the problem is with the network and/or the problem is with the device. The system gathers information from network monitoring software and determine which tower caused, for example, the call to drop. The system determines technological capability of the device from the device TAC number. The system suggests solutions to the network problems by suggesting adding a sector, tuning an antenna, etc., or if the device has problems, adjusting phone settings.

  • Patent number: 11730325
    Abstract: Examples herein describe techniques for communicating between data processing engines in an array of data processing engines. In one embodiment, the array is a 2D array where each of the DPEs includes one or more cores. In addition to the cores, the data processing engines can include streaming interconnects which transmit streaming data using two different modes: circuit switching and packet switching. Circuit switching establishes reserved point-to-point communication paths between endpoints in the interconnect which routes data in a deterministic manner. Packet switching, in contrast, transmits streaming data that includes headers for routing data within the interconnect in a non-deterministic manner. In one embodiment, the streaming interconnects can have one or more ports configured to perform circuit switching and one or more ports configured to perform packet switching.

  • Patent number: 11736362
    Abstract: An analysis system automates IP address structure discovery by deep analysis of sample IPv6 addresses using a set of computational methods, namely, information-theoretic analysis, machine learning, and statistical modeling. The system receives a sample set of IP addresses, computes entropies, discovers and mines address segments, builds a network model of address segment inter-dependencies, and provides a graphical display with various plots and tools to enable a network analyst to navigate and explore the exposed IPv6 address structure. The structural information is then applied as input to applications that include: (a) identifying homogeneous groups of client addresses, e.g., to assist in mapping clients to content in a CDN; (b) supporting network situational awareness efforts, e.g., in cyber defense; (c) selecting candidate targets for active measurements, e.g.

  • Patent number: 11729077
    Abstract: This disclosure describes techniques for configuring and managing scalable global private networks associated with a service provider. Different input mechanisms, such as an API, a UI, or a CLI may be utilized to configure, and manage a global private network that spans across the cloud in different geographic locations and connects to different stand-alone networks. The user may proactively use the input mechanisms to configure and query different network resources to reactively configure settings for reacting to one or more events. The input mechanisms may also be utilized to define the network resources to be modeled within the global private network as well as connections within the global network. A user may configure events/metrics to be monitored, tasks/workflows to be performed, and the like. In some configurations, a network management service (NMS) may perform health monitoring and reachability monitoring to identify possible issues in the global network.

    Abstract: A bearer creation system creates dedicated bearers for sessions requested by user equipment devices based on a policy associated with the user equipment device. The bearer creation system detects that a request to initiate a session has been sent by user equipment associated with a policy. The bearer creation system compares the request to initiate the session to information indicated by the policy, and determines whether to create a dedicated bearer for the session based on the comparison. The bearer creation system creates a dedicated bearer for the session based on a determination that a dedicated bearer should be created.
