Abstract: The present invention relates a system and a method of recognizing and addressing network alarms in a computer network. A network adapter is configured to receive network alarms related to operating condition of network devices present in the computer network, wherein the network devices are managed by different vendors. Information present in the network alarms is analyzed to determine elements indicating the operating condition of the network devices. The elements may comprise at least one of keywords, object identifiers, and values of the object identifiers. A trained data model is finally used for mapping the network alarms with standard attributes. Based on such mappings, the network alarms are then addressed.

Abstract: One aspect provides an apparatus for locking circuit boards in position between a pair of guide rails. The apparatus can include a slider attached to a sidewall of one guide rail. The slider is allowed to slide along the guide rail within a predetermined range and one or more plunger-and-spring assemblies. A respective plunger-and-spring assembly comprises a plunger and a spring surrounding the plunger, and the plunger is inserted into a through-hole on the sidewall of the guide rail such that a first end of the plunger can be aligned with a notch on a corresponding circuit board and a second end of the plunger is in contact with the slider. Sliding of the slider causes the spring to compress and decompress and the first end of the plunger to move in and out of the notch on the circuit board, thereby facilitating locking and unlocking of the circuit board.

Abstract: Examples described herein relate to a data protection policy management system (DPPMS) for tuning a data protection policy in events of failures. The DPPMS may detect a failure associated with an application that is protected via the data protection policy that includes settings corresponding to parameters comprising one or more of copy tiers, a data retention interval and a recovery point objective (RPO) for the copy tiers. The DPPMS may determine a type of the failure associated with the application. Further, the DPPMS may select, based on the type of the failure, at least one parameter of the parameters to be tuned in response to detection of the failure. Moreover, the DPPMS may tune the settings corresponding to the at least one selected parameter to adapt the data protection policy.

Abstract: Example implementations relate to a method for reconfiguring a network based on network traffic comparison. The first network supports multicast Domain Name Service (mDNS) query with multicast query-response messages. The method includes determining a client type for each client device and a first average packet count for each client type in a first network. The method includes receiving a second average packet count for each corresponding client type from a second network. The second network supports mDNS query with unicast query-response messages. A difference between the first average packet counts and the second average packet counts for corresponding client types is computed. The first network is reconfigured to respond to mDNS query with unicast query-response messages when the difference computed for at least one client type in the first network and each corresponding client type in the second network is above a predefined threshold.

Abstract: A system for facilitating sender-side congestion control is provided. During operation, the system, on a sender node, can determine the utilization of a buffer at a last-hop switch to a receiver node based on in-flight packets to the receiver node. The receiver node can be reachable from the sender node via the last-hop switch. The system can then determining a fraction of available space in the buffer for packets from the sender node based on the utilization of the buffer. Subsequently, the system can determine whether the fraction of the available space in the buffer can accommodate a next packet from the sender node while avoiding congestion at the buffer at the receiver node. If the fraction of the available space in the buffer can accommodate the next packet, the system can allow the sender node to send the next packet to the receiver node.

The system can maintain state information of individual packet flows, which can be set up or released dynamically based on injected data. Each flow can be provided with a flow-specific input queue upon arriving at a switch.

Abstract: Systems and methods are provided for incorporating an optimized dispatcher with an FaaS infrastructure to permit and restrict access to resources. For example, the dispatcher may assign requests to “warm” resources and initiate a fault process if the resource is overloaded or a cache-miss is identified (e.g., by restarting or rebooting the resource). The warm instances or accelerators associated with the allocation size that are identified may be commensurate to the demand and help dynamically route requests to faster accelerators.

The gap may form a complete separation between the first and second portions of the conductive layer.
