Abstract: A system may be configured to identify from among a plurality of access points in an area in communication with a network, a first access point associated with the area. In addition the system may also be configured to determine first location-related data for the first access point. Determining second location-related data for a second access point of the plurality of access points, the second access point being interior to the first access point within the network includes exchanging ranging data indicative of a first relative distance between the first access point and the second access point, the ranging data based at least in part on ranging message exchange measurements, and communicating the first location-related data from the first access point to the second access point.

Abstract: In one embodiment, a network assurance service that monitors a network detects a network anomaly in the network using a machine learning-based anomaly detector. The network assurance service identifies a set of network conditions associated with the detected network anomaly. The network assurance service initiates a network test on one or more clients in the network that exhibit the identified network conditions. The network assurance service retrains the machine learning-based anomaly detector based on a result of the network test.

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: In one embodiment, a network assurance service that monitors a network maps time series of values of key performance indicator (KPIs) measured from the network to lists of unique values from the time series. The service sets a target alarm rate for anomaly detection alarms raised by the network assurance service. The service uses an optimization function to identify a set of thresholds for the KPIs. The optimization function is based on: a comparison between the target alarm rate and a fraction of network issues flagged by the service as outliers, KPI thresholds selected based on the lists of unique values from the time series, and a number of thresholds that the KPIs must cross for the service to raise an alarm. The service raises an anomaly detection alarm for the monitored network based on the identified set of thresholds for the KPIs.

Abstract: Offloading of location computation from a location server to an access point through the use of projections on base phase vectors may be provided. First, an Access Point (AP) may receive a set of two or more base phase vectors from a location server. Next, the AP may measure a measured phase vector for a first signal from a user device. Then, the AP can determine projection values based on a comparison of the measured phase vector to each base phase vector. From these comparisons, the AP can determine a subset of base phase vectors with the highest projection values. The AP can then send the projection values and the subset of base phase vectors to the location server, wherein the location server determines the device location from these projection values and subset of base phase vectors.

Abstract: Determining a device's location in a space in real time is computing intensive. To offload some of the workload in conducting this hyperlocation, the access points in the network conduct some of process in determining the location of a device. The cloud determines a restricted AoA search area based on previous client locations. After this determination, a three-dimensional (3D) AoA search is conducted by each AP in the restricted area (restricted by a range of azimuth directions) for a device. Finally, each AP reports a location(s) for the device, which comprises weights for selected angular sectors. The cloud can then construct a probability heat map for location computation from the weights provided from each AP for the device.

Abstract: In one embodiment, a network assurance service that monitors a plurality of networks obtains characteristic data regarding network entities deployed in the plurality of networks. The network assurance service assigns the network entities to entity clusters by applying a clustering mechanism to the characteristic data regarding the network entities. The network assurance service generates, for each of the entity clusters, a training dataset using the characteristic data for the network entities assigned to that cluster. The network assurance service uses, for each of the entity clusters, the training datasets for an entity cluster to train a machine learning-based model that models the behavior of that entity cluster.
