Abstract: Disclosed are methods and systems for improved wireless terminal roaming. In some embodiments, a management module determines access point density metrics for a plurality of centrally managed access points of a communications site. The density metric considers an average RSSI of access point signals received by other access points of the site, and each access point's contribution to the average. A determination of whether a particular wireless terminal roams is based on the density metrics of the source and target access point, as well as statistics relating to a current capacity of each of the access points. The disclosed embodiments may determine that a wireless terminal should transition/roam away from an access point even when that access point's RSSI value at the wireless terminal is above a threshold that would cause traditional methods to inhibit roaming.

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 that enable onboarding of a plurality of heterogeneous client devices with secure access to a wireless network using a network management system (NMS). The NMS has a memory to store a plurality of private pre-shared keys (PPSKs), where each PPSK is provisioned for a particular client device or a particular group of client devices. In response to a key lookup request from an access point (AP) device for a client device, the NMS performs a key lookup and, in response to identifying a PPSK provisioned for the client device, authenticates the client device to access the wireless network via the AP device. The NMS then manages one or more of tracking the client device, policy application to the client device, or handling of network traffic from the client device while connected to the wireless network using the PPSK as an identifier of the client device.
