Abstract: 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.

Abstract: A computer implemented method of monitoring and controlling a target system, such as a communication network or an industrial process. The method includes receiving (301) information about anomalies in operation of the target system detected by an automated anomaly detection mechanism; automatically determining (302) certainty characteristics of the detected anomalies; submitting (303) detected anomalies to expert evaluation in priority order determined based on the certainty characteristics; and adjusting (304, 305) the determination of certainty characteristics of the detected anomalies and/or the automated anomaly detection mechanism based on results of the expert evaluation.

Abstract: A method for creating a dedicated optimal local grid around a place of interest comprises: a) iteratively updating the local grid size such as to satisfy statistical constraints; and b) discontinuing the iterative process of step (a) when a predefined threshold of said statistical constraint is reached.
