A network management system. In particular implementations, a method includes establishing a persistent session with one or more network management servers, where each persistent session is identified relative to a session identifier; authenticating one or more clients requesting access; receiving, from a client, a request to access a selected network management server of the one or more network management servers; generating a ticket for the client; and transmitting a redirection message to the client, where the redirection message identifies the selected network management server and includes the ticket and the session identifier corresponding to the selected network management server.

Unified user interface for network management systems

In one embodiment, a method includes identifying a plurality of network elements for reinitiation, wherein the network elements are operative to manage at least one child element; selecting a first network element from the plurality of network elements, transmitting a disable message to the first network element; determining whether the at least one child element has migrated to one or more alternate network elements; and conditionally transmitting a reinitiation message to the first network element.

Coordinated reboot mechanism reducing service disruption in network environment

Methods, apparatuses and systems directed to, or facilitating, the graphical display of status information in wireless network management systems. In one implementation, the present invention provides a graphical user interface that allows a network administrator to readily ascertain the overall status of a wireless network, and quickly identify the network element(s) within the network that are associated with any potential problem or condition. In another implementation, the present invention provides a graphical user interface that provides status icons that efficiently convey status information for corresponding access points. In another implementation, the present invention provides a hierarchical network model that facilitates network data management, configuration and display tasks associated with wireless network management systems.

Graphical display of status information in a wireless network management system

In one embodiment, a method includes receiving calibration data, computing one or more attributes of a pathloss model based on the calibration data, computing estimated locations using the received signal strength values of the calibration data points, associating location errors with the one or more calibration data points, and computing a location quality within a region based on the associated location errors.

Location inspector in wireless networks

A troubleshooting system. In particular implementations, a method includes collecting, from a first wireless network element, PEM state associated with a wireless client having a connection problem, and collecting log data associated with the wireless client from the first wireless network elements and one or more other wireless network elements. The method further includes correlating the PEM state and log data based on a network security protocol employed by the wireless client, where the network security protocol corresponds to an expected sequence of events. The correlating includes correlating events and messages collected based on the expected sequence of events, and comparing the correlated sequence of events to a data store of diagnostic information to identify one or more possible causes of the connection problem.

Diagnostic functionality for wireless client connectivity problems in wireless networks

A troubleshooting system. In particular implementations, a method includes receiving a request for troubleshooting, where the request comprises identifying information for a wireless client having a connection problem. The method further includes identifying network nodes that are sources of log data associated with connection activity of the wireless client, and invoking troubleshoot logging on one or more central controllers for the wireless client. The method further includes polling the identified network nodes for the log data, and identifying one or more potential causes of the connection problem based on correlating the data logs.

Troubleshooting of Wireless Client Connectivity Problems in Wireless Networks

In one embodiment, a method includes storing, in a data store, a physical network model of a network environment, the network environment comprising one or more central controllers and one or more access points each operative to associate with a central controller, the physical network model comprising one or more region objects, each region object corresponding to a physical region of the network environment, each region object further including one or more radio frequency (RF) coverage maps, each RF coverage map defining a location of one or more access points and RF properties of a physical space; receiving a first mapping definition between a location server and a one or more region objects of the physical network model; receiving a second mapping definition between the location server and one or more central controllers; transmitting the one or more region objects in the first mapping definition to the location server; and configuring the location server and the one or more central controllers in the second mapping definition to interoperate.

Management of distributed location servers

Coordinated reboot mechanism reducing service disruption in network environments

In one embodiment, a method includes displaying a geographical map illustrating locations of a plurality of wireless nodes of a mesh network; displaying a hierarchically-arranged filter that shows a hierarchical relation of the plurality of wireless nodes; receives a filter configuration; and displaying in the geographical map a subset of the plurality of wireless nodes based on the filter configuration.
