Abstract: A method includes receiving, by a network management system, network data from a plurality of network devices configured to provide a network at a site; receiving, by the processing circuitry, user impact data from a plurality of client devices that access the network at the site; determining, based on the network data, a pattern of one or more network events occurring over time; correlating in time the pattern of the one or more network events to an adverse user impact event indicated by the user impact data received from the plurality of client devices; and determining, in response to the correlating, an instance of overwhelming network traffic having an adverse user impact. In some examples, the network data includes network traffic impact data, such as a number of packets dropped at a switch port due to congestion.

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: Techniques are described by which a network management system (NMS) provides a common user interface (UI) to enable a user to collectively configure network devices to establish an EVPN topology. For example, an NMS is configured to: generate data representative of a common UI comprising UI elements representing a plurality of network devices to be configured in an EVPN topology; receive, via the common UI, an indication of a user input selecting one or more of the UI elements representing selected network devices; generate UI elements representing a plurality of ports of the selected network devices; receive, via the common UI, an indication of a user input selecting the UI elements representing one or more selected ports; and generate, based on the one or more selected network devices and one or more selected ports, topology relationship information of the one or more selected devices to establish the EVPN topology.

Abstract: A network management system (NMS) initiates, for each of a plurality of wireless and/or wired client devices, a wireless/wired stateful machine configured to continuously monitor at least one pre-connection state and at least one post-connection state of a corresponding wireless/wired connection session, and determines one or more network connection assessments for the plurality of wireless/wired client devices based on success or failure of the pre-connection states and/or the post-connection states. The NMS may also output a notification including identification of a root cause of any network connection failure(s) and/or automatically invoke remedial action intended to address or mitigate the root cause of the network connection failure(s).
