The evaluation of the query includes determining the classes that satisfy or fulfill the one or more criteria, determining one or more second classes that match, or inherit from, the one or more classes, partially evaluating the additional criterion within respective contexts of the candidate nodes and each of the one or more second classes, based on the partial evaluation, processing the query to determine the node instances, and provisioning or presenting an entity represented by a node instance of the node instances to the service.

Abstract: In one embodiment, a network assurance service that monitors a network detects an anomaly in the network by applying an anomaly detector to telemetry data collected from the network. The service sends first data to a user interface that causes the interface to present the detected anomaly and one or more candidate root cause metrics from the telemetry data associated with the detected anomaly. The service receives feedback regarding the candidate root cause metric(s) and learns a root cause of the anomaly as one or more thresholds of the candidate root cause metric(s), based in part on the received feedback regarding the candidate root cause metric(s). The service sends second data to the user interface that causes the user interface to present at least one of the candidate root cause metric(s) as a candidate root cause of a subsequent detected anomaly, based on the learned threshold(s).

Abstract: A system may include a historical managed software system data store that contains electronic records associated with controllers and deployed workloads (each electronic record may include time series data representing performance metrics). An entropy calculation system, coupled to the historical managed software system data store, may calculate at least one historical entropy value based on information in the historical managed software system data store. A detection engine, coupled to a monitored system currently executing a deployed workload in the cloud computing environment, may collect time series data representing current performance metrics associated with the monitored system. The detection engine may then calculate a current monitored entropy value (based on the collected time series data representing current performance metrics) and (iii) compare the current monitored entropy value with a threshold value (based on the historical entropy value).

Abstract: A method and system for assigning slot addresses to modules in a fault tolerant industrial control system includes a pair of backplane switches on each base. Each backplane switch is configured to communicate between one backplane and the modules located on the base and to communicate between backplane switches located at adjacent bases. A backplane switch on a bank master base first assigns a base address and slot addresses to itself. The backplane switches on each additional base initiate transmission of a base address request. A base address response, including a base address and slot numbers for the adjacent base, is transmitted after a base has its own address assigned. Each base repeats the process in sequence along the bank, incrementing the base address by one and the slot address by the number of slots on the base and passing the new base and slot addresses along the bank.

Abstract: Systems, devices and methods are described for facilitating gateway prioritization. A system includes a gateway, a first node, and a second node coupled by an internal link. The gateway instantiates an allocator which allocates a link characteristic of the internal link based on a first resource request by the first node and in view of a second resource request by the second node. The requests identify a link characteristic for the internal link. The allocator allocates the link characteristic between the first node and the second node based on a ranking of the first node and the second node. The first link characteristic may be an internal link bandwidth. An ISP server is coupled by an external link to the gateway. The external link includes an external link characteristic which the first resource request identifies and the allocator allocates in view thereof.

Embodiments create an authenticate target action and register a cache listener for a cache that includes a filter to listen for a target action response that is responsive to the authenticate target action, the filter listing a plurality of bridges assigned to an on-premise active directory. Embodiments randomly select one of the plurality of bridges and sends the authenticate target action to the active directory via the selected bridge. Embodiments wait for a cache callback and, at the cache callback, receive a target action response that includes a result of the authenticate action.

Abstract: In some implementations, formation of loops between nodes in an RPL network may be avoided. A node that receives a neighbor-discovery message may determine, based on a parent-child status, whether the neighbor-discovery message was received from a parent of the node. If the neighbor-discovery message was received from the parent, the node may transmit an error code to the parent. In addition, the node may determine, based on a comparison of reliability rankings, whether the neighbor-discovery message was received from a node with relatively high reliability, such as a potential grandparent node. If the neighbor-discovery message was received from a high-reliability node, the node may transmit an error code to the high-reliability node. Furthermore, the node may reduce network traffic by withholding a neighbor-detection message from a child node. The node may transmit a response to neighbor-detection messages received from the child node.
