Abstract: In one embodiment, a network assurance system that monitors a network labels time periods with positive labels, based on the network assurance system detecting problems in the network during the time periods. The network assurance system assigns tags to discrete portions of a feature space of measurements from the monitored network, based on whether a particular range of values in the feature space has a threshold probability of occurring during a positively-labeled time period. The network assurance system determines a set of the assigned tags that frequently co-occur with the positively-labeled time periods in which problems are detected in the network. The network assurance system causes performance of a mitigation action in the network based on the set of assigned tags that frequently co-occur with the positively-labeled time periods.

Abstract: In one embodiment, a network assurance service that monitors a network calculates network frequency distributions of a performance measurement from the network over a plurality of different time periods. The service calculates entity frequency distributions of the performance measurement for a plurality of different groupings of one or more network entities in the network over the plurality of different time periods. The service determines distance measurements between the network frequency distributions and the entity frequency distributions. The service identifies a particular one of the grouping of one or more networking entities as an outlier, based on a change in distance measurements between the network frequency distributions and the entity frequency distributions for the particular grouping. The service provides an indication of the identified outlier grouping to a user interface.

Abstract: Location data is obtained from signals transmitted by a first plurality of mobile wireless devices in a wireless network, wherein the first plurality of mobile wireless devices are moving within a predefined space, and wherein the location data comprises a plurality of location data time points, each location data time point including a timestamp, a unique mobile wireless device identifier, and location information indicating where in the predefined space an associated mobile wireless device is located. For each mobile wireless device, location data time points are aggregated to generate a set of aggregated location data for each mobile wireless device, and the set of aggregated location data is analyzed to determine characteristics corresponding to time-dependent behavior and location-specific behavior of the corresponding mobile wireless device. A user of each corresponding mobile wireless device is classified into a category of a plurality of categories based on the determined characteristics.

Abstract: In one embodiment, a supervisory service for a software-defined wide area network (SD-WAN) tracks a performance metric for a tunnel in the SD-WAN. The supervisory service computes a cumulative distribution function (CDF) for the tracked performance metric. The service assesses curvature of the CDF for the tracked performance metric relative to a service level agreement (SLA) threshold of an application for that performance metric. The service controls assignment of traffic for the application to the tunnel, based on the assessed curvature of the CDF for the tracked performance metric relative to the SLA threshold of the application for that performance metric.

Abstract: Various implementations disclosed herein provide a method for anonymizing data in a distributed hierarchical network. In various implementations, the method includes determining a first set of attribute hierarchy counts that indicate a number of occurrences of corresponding attributes that are stored at the first network node and have not been transmitted upstream towards the hub. In various implementations, the method includes receiving, from a second network node, a second set of attribute hierarchy counts that indicate a number of occurrences of corresponding attributes at the second network node. In various implementations, the method includes determining whether a sum based on the first and second set of attribute hierarchy counts satisfies an anonymization criterion. In some implementations, the sum indicates a total number of occurrences for a corresponding attribute that are stored at the first and second network nodes and have not been transmitted upstream towards the hub.

Abstract: In one embodiment, a network assurance service that monitors a network detects a pattern of network measurements from the network that are associated with a particular network problem. The network assurance service tracks characteristics of the detected pattern over time. The network assurance service uses the tracked characteristics of the detected pattern over time as input to a machine learning-based pattern analyzer. The pattern analyzer is configured to determine whether the detected pattern is a perpetual or transient pattern in the network, and the pattern analyzer is further configured to detect anomalies in the characteristics of the pattern. The network assurance service initiates a change to the network based on an output of the machine learning-based pattern analyzer.
