Abstract: In one embodiment, a device generates a plurality of smoothed timeseries by applying smoothing envelopes of different durations to a timeseries of a path metric for a path in a network that is used to convey traffic of an online application. The device uses the plurality of smoothed timeseries and the timeseries of the path metric to make predictions as to whether the path will provide an unacceptable user experience in the online application. The device selects a smoothing envelope of a particular duration, by comparing performance metrics for the predictions. The device uses a timeseries of the path metric smoothed using the smoothing envelope of the particular duration to make predictive routing decisions in the network for the traffic of the online application.

Abstract: Systems, methods, and computer-readable media for annotating process and user information for network flows. In some embodiments, a capturing agent, executing on a first device in a network, can monitor a network flow associated with the first device. The first device can be, for example, a virtual machine, a hypervisor, a server, or a network device. Next, the capturing agent can generate a control flow based on the network flow. The control flow may include metadata that describes the network flow. The capturing agent can then determine which process executing on the first device is associated with the network flow and label the control flow with this information. Finally, the capturing agent can transmit the labeled control flow to a second device, such as a collector, in the network.

Abstract: Techniques and mechanisms for processing broadcast data traffic for a plurality of user equipments (UEs) of a virtual network group are described herein. In one illustrative example, a user plane function may receive a broadcast packet from one of the UEs or a data network; perform a packet detection rule (PDR) lookup for the broadcast packet, for identifying a PDR and a forwarding action rule (FAR) associated with it; process the broadcast packet in accordance with an apply action of the FAR, for creating a tunnel management message having a payload which encapsulates the broadcast packet; and send the tunnel management message to a base station which is configured to perform unicast data delivery of the broadcast packet to each one of at least some of the plurality of UEs of the virtual network group. The user plane function may configured for use in a public cloud for 5G-as-a-Service (5GaaS).

Abstract: In one embodiment, a device provides, to a user interface, a timeseries for display of a probability over time of a network path violating a service level agreement (SLA) associated with an online application. The device receives, from the user interface, a plurality of thresholds for the timeseries that define periods of time during which application experience of the online application is believed to be degraded. The device trains, based on the plurality of thresholds, a machine learning model to predict when the application experience of the online application will be degraded. The device causes a predictive routing engine to reroute traffic of the online application based on a prediction by the machine learning model that the application experience of the online application will be degraded.
