Abstract: Techniques are described that detect areas with insufficient radio frequency (RF) coverage in a wireless network. A network management system (NMS) determines one or more service level expectation (SLE) metrics for each client device in a wireless network. The SLE metrics are aggregated to each access point (AP) in the wireless network, and each AP is assigned an AP score based on the aggregated SLE metrics. To identify potential coverage holes, the NMS groups APs having poor AP scores. If a root cause of the poor AP scores cannot be automatically resolved and if the poor AP scores persist for a predetermined period of time, the group of APs is determined to represent a true coverage hole. The NMS may generate a notification regarding recommended corrective actions to the customer and/or IT personnel.

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).

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) is configured to monitor and/or control a wireless network based on one or more roaming quality assessments. The NMS determines one or more roaming quality assessments for each roaming event and/or each network device in the wireless network. The roaming quality assessments include one or more of a roaming latency score, a signal quality score and/or a stability score. The roaming quality assessments may further include one or more suboptimal roam scores, sticky client scores, and/or interband scores. The NMS may further detect one or more ping-pong roaming events or excessive roaming events.

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: Techniques are described by which a network management system (NMS) receives, from a plurality of access points (APs) configured to provide a wireless network, received signal strength indicator (RSSI) values. The NMS generates, based on the RSSI values, a graph of the plurality of APs, wherein the graph of the plurality of APs includes a plurality of clusters, wherein each cluster comprises a subset of the plurality of APs that are grouped based on strength of connectivity between the subset of the plurality of APs. The NMS generates, based on the graph, an upgrade plan to upgrade the plurality of APs, wherein the upgrade plan comprises a plurality of batches, wherein each batch includes a selection of at least one AP from each of one or more of the plurality of clusters. The NMS sends the upgrade plan to an orchestrator to execute the upgrade plan.

Abstract: The disclosure describes one or more techniques for performing automated scheduling and/or orchestration of synthetic tests for network sites. For example, a network management system comprises a memory and one or more processors in communication with the memory and configured to: determine, based on data received from a plurality of network devices of a network, a network condition to perform a test, wherein the network condition comprises one or more of a time window to perform the test or one or more network devices of the plurality of network devices to perform the test; instruct, based on the network condition, the one or more network devices to perform the test; identify, based on data obtained from the one or more network devices that performed the test, an issue of the network; and perform an action based on the identified issue.
