Methods and apparatus for controlling access to and/or forwarding of communicated information, e.g. traffic, in a wireless communication system are described. The key, e.g., PSK, used to secure data that is transmitted to an access point for communication to a destination device is taken into consideration when deciding whether or not to provide the destination device access to the communicated content. The decision of whether or not to provide the destination device access to a communication may involve deciding whether or not to forward the received data to another device, e.g., another access point, for delivery to the destination device and/or may involve deciding whether or not to transmit the data to the destination device. If the destination device is not associated with, e.g., does not have access to and/or authorization to use, the key used to secure the received data, the data is not communicated to the destination device.

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.

Wireless transmissions from beacon devices are received at a plurality of receiver devices. The wireless transmissions comprise packets that carry information used for location-based services for mobile wireless devices. Content of one or more fields of the beacon packets received by one or more of the plurality of receiver devices is obtained. Measurement data associated with the transmissions received at the plurality of receiver devices is generated. Locations of the respective beacon devices are computed from the measurement data obtained by the plurality of receiver devices. Information identifying detected beacon devices and their locations are stored to maintain a location history of beacon devices over time locations. Changes from information contained in the location history are detected based on the locations computed for respective beacon devices from the measurement data and content of one or more fields of detected beacon packets.

Managing wireless beacon devices

Techniques are presented for detecting rogue wireless beacon devices. Wireless transmissions from beacon devices are received at a plurality of receiver devices. The wireless transmissions of the beacon devices comprise packets that carry information used for location-based services for mobile wireless devices. Content of one or more fields of the packets transmitted by the beacon devices and received by one or more of the receiver devices is obtained. The content of one or more fields of the packets is analyzed to detect an unauthorized beacon device. The analyzing operation may involve comparing the content of the one or more fields of the packets against a list that contains one or more identifiers for authorized beacon devices. In another form, analyzing may involve analyzing the content of the one or more fields of the packets with pattern information related to advertising content or advertising source.

Rogue wireless beacon device detection

A wireless data communication system includes an access port configured to wirelessly communicate with a plurality of mobile units within multiple basic service sets (BSS), and a wireless switch having multiple predefined wireless local area networks (WLANs). The wireless switch is configured to automatically map the WLANs to the basic service sets and transmit to the access port a configuration template depending upon the type of access port. In one embodiment, there are n basic service sets, each having a corresponding basic service set identifier (BSSID), and m WLANs, each having a corresponding WLAN index, wherein the m WLAN indices are uniformly mapped to the n BSSIDs such that each BSSID has substantially the same number of WLAN indices mapped thereto. In a particular embodiment, there are n=4 BSSIDs per access port and m=16 pre-mapped WLANs. In this way, the wireless switch and respective access ports can be set-up in a simplified manner, in much the same way that set-up is performed with traditional access points.

Methods and apparatus for simplified setup of centralized WLAN switching

Techniques are provided for load balancing among a plurality of wireless switches configured to support a plurality of clients including a first client. An initial home wireless switch can be configured to initially support the first client. The initial home wireless switch can select one of the wireless switches as a new home wireless switch for the first client. These techniques can be implemented, for example, in a wireless local area network.
