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).

The device obtains telemetry data from the plurality of paths for the online application. The device computes, based on the telemetry data, fate sharing metrics for the plurality of paths. The device controls routing of application traffic between the pair of network addresses, based on the fate sharing metrics for the plurality of paths.

Abstract: In one embodiment, a device receives path telemetry data for one or more network paths in a network over which traffic for an online application is conveyed. The device computes time series dynamics for the path telemetry data. The device determines a mapping of the time series dynamics to application experience metrics for the online application. The device routes traffic associated with the online application based on the mapping.

Abstract: In one embodiment, techniques are shown and described relating to traffic-based inference of influence domains in a network by using learning machines. In particular, in one embodiment, a management device computes a time-based traffic matrix indicating traffic between pairs of transmitter and receiver nodes in a computer network, and also determines a time-based quality parameter for a particular node in the computer network. By correlating the time-based traffic matrix and time-based quality parameter for the particular node, the device may then determine an influence of particular traffic of the traffic matrix on the particular node.

Abstract: In one embodiment, a supervisory service for a software-defined wide area network (SD-WAN) uses a plurality of different decision thresholds for a machine learning-based classifier, to predict tunnel failures of a tunnel in the SD-WAN. The supervisory service captures performance data indicative of performance of the classifier when using the different decision thresholds. The supervisory service selects, based on the captured performance data, a particular decision threshold for the classifier, in an attempt to optimize the performance of the classifier. The supervisory service uses the selected decision threshold for the classifier, to predict a tunnel failure of the tunnel.

Abstract: In one embodiment, a method comprises causing, by a network controller device, a first access point (AP) device to initiate a reverse sounding operation comprising wirelessly requesting a mobile constrained network device to transmit a null data packet (NDP) at a first transmission interval, wirelessly receiving the NDP at the first transmission interval, and generating a reception report describing reception of the NDP and including beamforming information; causing, by the network controller device, a second AP device to generate a corresponding reception report describing a corresponding wireless detection of the NDP at the first transmission interval; and causing, by the network controller device, the mobile constrained network device to connect to a selected one of the first AP device or the second AP device for an identified data flow based on the respective reception reports from the first and second AP devices.

Abstract: In one embodiment, a device obtains application experience metrics for an online application. The device predicts, based on the application experience metrics, future application experience metrics for each of a set of provider endpoints for the online application. The device selects, based on the future application experience metrics, a particular provider endpoint from among the set of provider endpoints. The device provides, to a Domain Name System (DNS) resolver, resolution information for one or more of the set of provider endpoints that causes a query for one of those provider endpoints to resolve to an address of the particular provider endpoint.

Abstract: In one embodiment, a labeling service receives telemetry data for a cluster of endpoint devices in a first network environment. The endpoint devices in the cluster are clustered by a device classification service based on their telemetry data and labeled by a device type classifier of the device classification service as being of an unknown device type. The labeling service obtains a first device type label for the cluster of endpoint devices via a first user interface. The labeling service identifies one or more other network environments in which endpoint devices are located that have similar telemetry data as that of the cluster of endpoint devices. The labeling service obtains device type labels for the cluster of endpoint devices via a selected set of user interfaces from the identified one or more other network environments. The labeling service validates the first device type label for the cluster using the device type labels obtained via the selected set of user interfaces from the identified one or more other network environments.
