摘要： Systems and methods for Segment Routing Traffic Engineering (SR-TE) with awareness of local protection include the advertisement of local protection information in effect at each SR capable node via Interior Gateway Protocol (IGP), Border Gateway Protocol Link-State advertisement (BGP-LS), telemetry, etc. A method includes determining local protection in effect at a node in a Segment Routing network; and advertising information based on the local protection via extensions in a routing protocol, e.g., IGP, BGP-LS, etc., associated with the Segment Routing network, wherein the information includes identity of protected elements and a type of the local protection.

摘要： A circuit interconnection structure has a cavity formed through an entire thickness between first and second surfaces. A first integrated circuit is mounted on the first surface. A device carrier comprises a first portion that fits within at least a portion of the cavity. A second portion of the device carrier rigidly connected to the first portion of the device carrier is attached to the first surface. A device positioned within the first portion of the device carrier and mounted to a mounting surface of the device carrier is substantially parallel to the first surface. The device comprises a second integrated circuit. A total thermal expansion of the device carrier between the second portion of the device carrier and the mounting surface is substantially equal to a total thermal expansion of the device between the second integrated circuit and the portion of the device mounted to the mounting surface.

摘要： A router configured to implement Border Gateway Protocol (BGP) includes circuitry configured to receive BGP updates from one or more BGP peers connected to the router, detect a trigger related to BGP updates where the trigger is indicative of a need to apply backpressure by the one or more BGP peers, and send a backpressure notification message to the one or more BGP peers based on the trigger, such that the one or more BGP peers apply the backpressure. The circuitry can be further configured to monitor one or more criteria associated with operation of the router, for the trigger.

摘要： Aspects of the subject disclosure may include, for example, receiving user-generated input. The user-generated input initiates a request for a first reduced configuration associated with a group of services to a client computing device associated with a user. Further embodiments can include obtaining a merged configuration associated with the group of services, obtaining staged system data associated with the group of services, and generating the first reduced configuration based on the merged configuration and the staged system data. Additional embodiments can include transmitting the first reduced configuration to the client computing device, wherein the client computing device presents the first reduced configuration on a display associated with the client computing device to the user. Other embodiments are disclosed.

摘要： Aspects of the subject disclosure may include, for example, a process for providing status indication, that includes receiving a control signal at a proximal end of an elongated flexible circuit assembly including a distal portion attached to and extending along at least a portion of an elongated, panel-facing edge of a planar circuit board. The process further includes directing the control signal around a bent portion of the elongated flexible circuit assembly and to a number of visual status indicators distributed along at least a distal end of the elongated flexible circuit assembly, wherein at least a portion of the number of visual status indicators is actuated, responsive to the control signal, to provide a visual indication of a status of equipment supported by the planar circuit board. Other embodiments are disclosed.

摘要： A backing plate assembly with jack screw for bare die device heat sink applications to ensure uniform loading. The jack screw is used to force a PCB support plate and mounting plate apart, and by doing so, compresses a plurality of springs and applies uniform pressure to the heat sink, which in turn applies pressure to the bare die of the BGA device. The single jack screw is essential to the design, as it creates a single point to apply torque and compress all the springs at the same time. A lock screw is meant to maintain the position of the PCB support plate and the mounting plate. Prior to assembly, the lock screw keeps the PCB support plate and mounting plate together to ease installation.

摘要： Systems and methods are provided for planning a future network topology with associated configuration settings of existing nodes in a network and enacting changes to the configuration settings after the network has been physically changed to the planned future topology. The method can include, in response to receiving a topology plan to change a network from an initial network topology to a future network topology, determine a configuration plan to change configuration settings of one or more existing Network Elements (NEs) deployed in the network in order to transition the network from the initial network topology to the future network topology, and, in response to discovering that the network has been physically changed to match the future network topology, automatically enact the configuration plan to change the configuration settings of the one or more existing NEs.

摘要： Aspects of the subject disclosure may include, for example, identifying a plurality of parameters for managing data in relation to an execution of an application, monitoring access to the data, determining, based on the monitoring, that first data that is located in a memory of the processing system has not been accessed in an amount of time that is greater than a first threshold, resulting in a first determination, determining, based on the plurality of parameters and the first determination, that the first data is a candidate for transfer to a persistent storage device, resulting in a second determination, and based on the second determination, causing the first data to be transferred to the persistent storage device. Other embodiments are disclosed.
