A network management system (NMS) automatically determines locations of deployed access points (APs) in a wireless network. The system identifies clusters of APs, wherein each AP in a cluster is a member of at least one robust quad, and wherein each robust quad in the cluster has three APs in common with another robust quad in the cluster. The NMS identifies one of the plurality of clusters as a global cluster and the remaining plurality of clusters as local clusters. The NMS determines coordinates of each node in the global cluster based on the coordinates of the anchor APs in the global coordinate system. For each local cluster, the NMS transforms the coordinates of each AP from the respective local coordinate system to the global coordinate system.

Determining locations of deployed access points

Techniques are described by which a network management system (NMS) is configured determine a specific wireless channel assigned to a first AP device. The NMS is further configured to determine one or more neighboring AP devices that are within a certain proximity of the first AP device and generate a packetized scan command for each of the one or more neighboring AP devices. The NMS is further configured to send the packetized scan command to each of the one or more neighboring AP devices and receive, from the first AP device and each of the one or more neighboring AP devices, signal samples of a client device connected to the first AP device on the specific wireless channel assigned to the first AP device. The NMS is further configured to, based on the received signal samples, determine a location within the site of the client device.

WiFi location enhancement

Systems, devices and techniques for an adaptive application-specific probing scheme are disclosed. An example network device includes memory configured to store a network address and probe protocol usable for probing a first network device associated with a source of an application, and one or more processors configured to determine a network address and probe protocol usable for probing the first network device, wherein the first network device comprises a server that is responsive to the probing, the server executing the application for the data flow, or a closest network device, to the server, that is responsive to the probing. The one or more processors are also configured to send to a second network device at a location serviced by the application, a message specifying the network address and probe protocol usable for probing the first network device.

Adaptable software defined wide area network application-specific probing

Techniques are described for monitoring application performance in a computer network. For example, a network management system (NMS) includes a memory storing path data received from a plurality of network devices, the path data reported by each network device of the plurality of network devices for one or more logical paths of a physical interface from the given network device over a wide area network (WAN). Additionally, the NMS may include processing circuitry in communication with the memory and configured to: determine, based on the path data, one or more application health assessments for one or more applications, wherein the one or more application health assessments are associated with one or more application time periods for a site, and in response to determining at least one failure state, output a notification including identification of a root cause of the at least one failure state.

Predicting network issues based on historical data

Application service level expectation health and performance

A system includes a plurality of access point devices (APs) configured to provide a wireless network at a site, each of the plurality of APs having a known location, and a network management system comprising 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: determine, based on a known location of a first AP of the plurality of APs, a known location of a second AP of the plurality of APs, and received signal strength measurements of wireless signals originating at one or more antennas of the first AP and received by one or more antennas of the second AP, an orientation angle of the second AP; and generate an output indicative of the orientation angle of the second AP.
