Abstract: In one embodiment, a supervisory service for a network obtains quality of experience metrics for application sessions of an online application. The supervisory service maps the application sessions to paths that traverse a plurality of autonomous systems. The supervisory service identifies, based in part on the quality of experience metrics, a particular autonomous system from the plurality of autonomous systems associated with a decreased quality of experience for the online application. The supervisory service causes application traffic for the online application to avoid the particular autonomous system.

Abstract: In one embodiment, a service tracks performance of a machine learning model over time. The machine learning model is used to monitor one or more computer networks based on data collected from the one or more computer networks. The service also tracks performance metrics associated with training of the machine learning model. The service determines that a degradation of the performance of the machine learning model is anomalous, based on the tracked performance of the machine learning model and performance metrics associated with training of the model. The service initiates a corrective measure for the degradation of the performance, in response to determining that the degradation of the performance is anomalous.

Abstract: In one embodiment, a device trains, using feedback from a reference cohort of users of an online application, a prediction model to predict a quality of experience metric for the online application based on network telemetry. The device uses the prediction model to predict quality of experience metrics for different cohorts of users of the online application. The device makes one or more comparisons between performance metrics for the prediction model for the different cohorts of users, based on the quality of experience metrics predicted for the different cohorts of users. The device retrains, based on the one or more comparisons, the prediction model using feedback from the reference cohort and a particular cohort from among the different cohorts of users.

Abstract: In one embodiment, a device computes, for each of a set of points of presence (PoPs) via which traffic for an online application can be sent from a location, application experience metrics predicted for the application over time. The device assigns, for each of the set of PoPs, weights to different time periods, based on measures of uncertainty associated with the predicted application experience metrics. The device generates, based on the weights assigned to the different time periods for each of the set of PoPs, schedules for probing network paths connecting the location to the online application via those PoPs. The device causes the network paths to be probed in accordance with their schedules. Results of this probing are used to select a particular PoP from among the set of PoPs via which traffic for the online application should be sent from the location during a certain time period.

Abstract: In one embodiment, a device obtains quality of experience measurements for an online application having application traffic conveyed via a first path in a backbone network between an ingress point and an egress point in the backbone network. The device makes a determination that the quality of experience metrics are indicative of degraded user experience with the online application. The device causes a label switched path to be scheduled between the ingress point and the egress point in the backbone network. The device causes at least a portion of the application traffic for the online application to be sent via the label switched path instead of the first path.

Abstract: In one embodiment, a device obtains probe results generated by probing a plurality of entities in a network from a first node in the network. The device generates a location identifier for the first node that represents its location in the network, based on the probe results. The device selects a configuration associated with the first node for use by a second node in the network, based on a difference between the location identifier for the first node and a location identifier for the second node. The device causes the configuration to be deployed to the second node.

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).
