Abstract: A network management system (NMS) is described that provides a granular troubleshooting workflow at an application session level using an application session-specific topology from a client device to a cloud-based application server. During an application session of a cloud-based application, a client device running the application exchanges data through one or more access point (AP) devices, one or more switches at a wired network edge, and one or more network nodes, e.g., switches, routers, and/or gateway devices, to reach a cloud-based application server. For a particular application session, the NMS generates a topology based on network data received from a subset of network devices, e.g., client devices, AP devices, switches, routers, and/or gateways, that were involved in the particular application session over a duration of the particular application session. In this way, the NMS enables backward-looking troubleshooting of the particular application session.

Abstract: This disclosure describes a system including a plurality of access point (AP) devices configured to provide a wireless network at a site; and a network management system (NMS) including a memory storing AP-side data collected by the plurality of AP devices and storing client-side data collected by a plurality of client devices connected to one or more of the AP devices to access the wireless network. The NMS is configured to correlate the client-side data for a particular client device of the plurality of client devices with a device identifier of the particular client device; associate, based on the device identifier, the client-side data for the particular client device and the AP-side data for the particular client device; analyze the client-side data and the associated AP-side data for the particular client device to detect a wireless issue; and output a notification including an indication of the wireless issue.

Abstract: Techniques are described by which a network management system (NMS) is configured to provide identification of root cause failure through the detection of network scope failures. For example, the NMS comprises one or more processors; and a memory comprising instructions that when executed by the one or more processors cause the one or more processors to: generate a hierarchical attribution graph comprising attributes representing different network scopes at different hierarchical levels; receive network event data, wherein the network event data is indicative of operational behavior of the network, including one or more of successful events or one or more failure events associated with one or more client devices; and apply a machine learning model to the network event data and to a particular network scope in the hierarchical attribution graph to detect whether the particular network scope has failure.
