  • Patent number: 11076436
    Abstract: A core network element, such as a PCRF and/or an MME, can determine that a Quality of Service (QoS) Class Indicator (QCI) of particular bearer set up between the core network and user equipment (UE) should be changed to a new QCI. When a control node, such as the MME, determines that no teardown delay conditions are met, the control node can send a bearer release message to a base station that instructs the base station to tear down all bearers for the UE, even if they are in use. In a dual connectivity arrangement, such as a E-UTRAN New Radio-Dual Connectivity (EN-DC) configuration, the base station can instruct a secondary base station to also release all bearers for the UE. The control node can instruct the base station to reestablish the particular bearer with the new QCI when the base station reestablishes the bearers for the UE.

    Abstract: Technologies for extending a subnet across on-premises and cloud-based deployments are provided. An example method may include creating a VPC in a cloud for hosting an endpoint being moved from an on-premises site. For the endpoint to retain its IP address, a subnet range assigned to the VPC, based on the smallest subnet mask allowed by the cloud, is selected to include the IP address of the endpoint. The IP addresses from the assigned subnet range corresponding to on-premises endpoints are configured as secondary IP addresses on a Layer 2 (L2) proxy router instantiated in the VPC. The L2 proxy router establishes a tunnel to a cloud overlay router and directs traffic destined to on-premises endpoints, with IP addresses in the VPC subnet range thereto for outbound transmission. The cloud overly router updates the secondary IP addresses on the L2 proxy router based on reachability information for the on-premises site.

  • Patent number: 10999127
    Abstract: Remediation of network devices that are failing is accomplished using a Shared Failure Domain (SFD) database that provides neighboring device/link information to remediation tools. SFD refers to a group of objects (links/devices) that share a same failure model. A state change of one or multiple of the objects results in a corresponding action on other devices linked together through the SFD. Moreover, the SFD data is available in a central repository and software tools consult the central repository for failure domain data before taking remedial actions. SFD data is generated using configuration generation and device state. Software tools lookup SFD data during operational events (device/link down) and take appropriate actions on the neighboring devices.

    Abstract: Computing device and methods for performing synchronization and resynchronization of networking information with a server. During standard operations, local networking data discovered by the computing device are transmitted to the server, and server networking data (discovered by the server) are received from the server. Upon occurrence of a pre-defined event at the computing device preventing exchange of information between the computing device and the server, a resynchronization of the local networking data and server networking data is performed. The synchronization and resynchronization mechanisms are based on unique version numbers respectively generated by the computing device and the server.

  • Patent number: 10972382
    Abstract: A node in a mesh network includes insertion circuitry to selectively delay first packets prior to insertion in a mesh network by a first time interval corresponding to a maximum failure detection time interval for the mesh network based on whether a failure has been detected in the mesh network. The node includes reception circuitry configured to selectively delay second packets received from the mesh network by a second time interval depending on whether the failure has been detected. The second time interval equals a maximum latency for the mesh network minus a sum of the maximum failure detection time interval and a propagation time along a working path. If a failure is detected, the second packets are delayed by a third time interval determined based on the maximum latency, the maximum failure detection time interval, and a propagation time along a backup path for the working path.
