摘要： Techniques for internet last-mile outage detection are disclosed herein. The techniques include methods for monitoring, by a network appliance associated with a network, a plurality of network nodes, detecting, by the network appliance, that a network node of the plurality of network nodes in a last mile of the network has disconnected from the network, overlaying, by the network appliance, the network node over a network model for at least a portion of the network including the network node to generate a model overlay, and determining, by the network appliance, a last mile outage source associated with a disconnection of the network node by identifying a lowest common ancestor node of the network node from the model overlay. Systems and computer-readable media are also provided.

摘要： Systems and methods for segmenting computer environment data can include a computer system obtaining data of a computer environment including a plurality of assets. The computer system can filter, using the data and one or more first criteria, the plurality of assets to identify a set of filtered assets. The computer system can determine, using the data, a state of each asset of the set of filtered assets, and identify one or more asset clusters within the set of filtered assets, using one or more slicing criteria. Each asset cluster can include assets of the set of filtered assets identified based on corresponding values of the one or more slicing criteria. The computer system can generate a visual representation of an asset cluster of the one or more asset clusters, and assign the visual representation to a user account or a computing device associated with a user profile.

摘要： In an example, a method includes receiving source data that includes multiple nodes arranged in a directed acyclic graph (DAG) in which each child node of a set of child nodes has multiple incoming edges. The method includes converting the DAG to a tree in which each of the nodes has no more than one incoming edge. The method includes displaying, based on the tree, a graphical diagram with graphical objects that represent nodes of the source data, including displaying a different child graphical object for each child node of the set of child nodes in a corresponding intersection area of two corresponding container graphical objects, the corresponding intersection area representing a corresponding intersection area node in the tree.

摘要： The invention provides a method for the temporal monitoring and visualization of the health of a direct interconnect network wherein discovered and configured nodes provide node telemetry data from each node or every port on each node at time interval, and the node telemetry data is stored in a temporal datastore at each time interval with a timestamp for a retention period, such that the temporal datastore contains a temporal history of node telemetry data from each node or every port on each node during the retention period. The node telemetry data is analyzed, alarms are raised as necessary, a health status commensurate with the severity of the node telemetry data is assigned and stored for each node or every port on each node, and a health score is calculated for such nodes and ports based on the assigned health status for use by a user interface. The user interface provides various novel visual representations of the health of nodes and ports based on the calculated health score, and this visual representation may display node and port health for any specific time during the retention period as desired.

摘要： The present disclosure provides a method for a network analytics tool capable of analyzing a time-varying set of parameter values for each of a plurality of measurable parameters and visually outputting a plurality of visualization objects. Each of the visualization objects comprise one or more visualization items, each visualization item representative of one of the plurality of measurable parameters. The method comprises: obtaining, for each of the plurality of visualization objects, a value of a first object-related metric and causing generation of a sensory-perceptible output indicative of a visualization object ranking established on the basis of the obtained value of the first object-related metric of each of the plurality of visualization objects. Obtaining a value of the first object-related metric includes, for each of one or more of the plurality of visualization objects, determining a value of the first object-related metric based at least on the set of parameter values of the measurable parameter of each visualization item included in the visualization object.

摘要： To meet the stringent 5G radio access network (RAN) service requirements, layers one and two need to be processed in essentially real time. Thus, prompt anomaly detection is important to prevent negative impacts on customer experience, which is critical for mobile networks to meet the stringent service requirements. However, monitoring networks for anomalies is difficult due at least to (1) the resource constrained edge deployments in which the vRAN resides, (2) the variety of anomaly types and fault locations making anomalies difficult to detect, and (3) the low frequency of anomalies leading to unbalanced data sets for training, among others. The present application addresses these issues by decoupling anomaly detection at the infrastructure layer (servers, NICs, switches, etc.) from anomaly detection at the VNF layer (L1, high-DU, CU). This enables different techniques for identifying anomalies and for reducing the monitoring overhead that is tailored to each layer.
