  • Publication number: 20250217259
    Abstract: Techniques are disclosed for a network management system (NMS) that performs quality of service (QoS) monitoring and troubleshooting of user experience issues occurring outside of a network managed by the NMS using data obtained from third-party sources. For example, an NMS obtains third-party data of a third-party application server or third-party service provider server from a third-party monitoring vendor. The NMS identifies a user experience issue indicated by the third-party data and stitches the third-party data to network data received from network devices. The NMS determines a root cause or a remedial action of the user experience issue based at least on the network data received from the one or more network devices. The NMS generates a notification for presentation to an administrator device which identifies the root cause or the remedial action of the user experience issue.

  • Publication number: 20250158894
    Abstract: Techniques are described for predicting a wide area network (WAN) issue based on detection of service provider connection swapping. A cloud-based network management system (NMS) obtains connection event data for one or more network access server (NAS) devices at a site, where each event included in the connection event data comprises a connection or disconnection event of a connection session provided by a service provider. The NMS detects a number of connection swaps in the connection event data over a time window, where a connection swap includes a change from a first connection session provided by a first service provider to a second connection session provided by a second service provider. Based on the detected number of connection swaps satisfying a threshold, the NMS predicts a root cause of the connection swaps as a WAN issue and generates a notification of the predicted root cause of the connection swaps.

  • Publication number: 20240223434
    Abstract: Techniques are described for detecting that a client device physically connected to a network device is “stuck,” that is, the client device is not sending or receiving network packets with the network device. A network management system (NMS) receives current network statistics of ports of network devices with respect to client devices physically connected to the ports. The NMS identifies a candidate client device connected to a particular port of a particular network device for which the current network statistics indicate an issue. The NMS detects anomalous behavior of the candidate client device based on one or more features of the current network statistics, historical baseline statistics associated with the candidate client device, and peer statistics associated with one or more peer client devices of a same device type as the candidate client device. The NMS outputs a notification of the anomalous behavior.
