  • Patent number: 9161293
    Abstract: A method, apparatus and computer program product for using Received Signal Strength Indicator (RSSI) filtering to provide air-time optimization in wireless networks is presented. At least one message is received at an Access Point (AP) from a mobile unit (MU). A determination is made by the AP whether a received Signal Strength indicator (RSSI) associated with the at least one message from an MU is greater than a predetermined threshold. When the RSSI value associated with the at least one message from na MU is greater than to said predetermined threshold, then a response is generated by the AP and sent to the MU.

  • Patent number: 8918847
    Abstract: A system and method for authenticating a layer 7 client application (application layer) based on a layer 2 (data link layer) or a layer 3 (network layer) authentication is provided. A request to authenticate to a network is received from a communication device. The request to authenticate to the network is for a layer 2 or layer 3 authentication. The communication device is authenticated to the network based on having the necessary credentials. A request is received to authenticate a layer 7 client application running on the communication device. The layer 7 client application running on the communication device requires a layer 7 authentication. The layer 7 client application running on the communication device is authenticated based on the layer 2 or layer 3 authentication.

  • Patent number: 8867507
    Abstract: A split-plane mobility network architecture separates control and data plane operations typically encapsulated in a conventional wireless controller. Configurations provide a unified split-plane mobility switch that separates the data transport and switching in a separate hardware element, and performs control plane operations via exchanges with a centralized topology, rather than simply by adjacent switches within range. In contrast to conventional switch deployment, in which the same switch handles processing demands of the control plane and the data plane, the disclosed approach separates the data plane processing base by employing a mobility agent to define adjacent switch visibility. Thus, the routing capabilities of the data plane may be enhanced, such as to handle increasingly bandwidth-hungry applications of the same user base, without uprooting the infrastructure defined by the control plane.

  • Patent number: 8428021
    Abstract: Methods, apparatus and a computer program product provide for a network architecture implemented between a Wireless Switching Point and a remote Wireless Controller. The Wireless Switching Point contains only a first data plane portion. At least one incoming data packet is received at a respective port of the Wireless Switching Point. Based on data included within the at least one incoming data packet, the Wireless Switching Point determines a first current network interface utilized by at least one port of the Wireless Switching Point. The Wireless Switching Point uploads the first current network interface to a remote Wireless Controller—which implements a first control plane capability on behalf of the Wireless Switching Point. After uploading the first current network interface, the Wireless Switching Point receives an update, provided by the remote Wireless Controller, to the first current network interface.
