  • Patent number: 7082535
    Abstract: Architecture for controlling access by a Light Extensible Authentication Protocol (LEAP)-compatible wireless client to a network that utilizes a challenge/handshake authentication protocol (CHAP). A proxy service is hosted on a network server disposed on the network, and accessed in response to receiving access information from the client. The access information is processed with the proxy service into CHAP-compatible access information, and forwarded to a CHAP-based access control server disposed on the network to determine whether to grant network access to the client.

  • Publication number: 20060129807
    Abstract: A wireless authentication protocol. Access to a network is managed by providing a challenge-handshake protocol within the Extensible Authentication Protocol for authentication between a client and the network.

  • Publication number: 20060094440
    Abstract: A method for multicast load balancing in a wireless network having a plurality of access points. The method includes setting a maximum Internet protocol multicast bandwidth for the access points, receiving an admissions control request from a client at one of the access points, and determining whether the admissions control request from the client is for an admitted or unadmitted multicast stream at the access point. The access point is responsive to the admissions control request for the admitted multicast stream by servicing the admitted multicast stream and to the admissions control request for the unadmitted multicast stream by servicing the unadmitted multicast stream where the bandwidth required for the unadmitted multicast stream, plus that portion of the access point bandwidth currently used for all existing downlink multicast streams, does not exceed the maximum internet protocol multicast bandwidth for the access point.

  • Patent number: 7013157
    Abstract: A packet format for multicast messages which designates a single receiver to send an acknowledgment to the multicast message. The designated receiver responds to the multicast message with an acknowledgment. If the designated receiver does not respond to the multicast message, the message is resent. The resent message may designate a different receiver for acknowledging the message.

  • Publication number: 20050060319
    Abstract: A technique for network planning that includes an interface for guiding a network user through the network allocation process, such as defining groups of clients based on their capabilities. Portions of the wireless local area network infrastructure, e.g., access points, are allocated among the groups. When a client attempts to associate with an access point, the access point determines the client capabilities. If the client is supported by the access point, the access point allows the client to associate and sends the client a message that contains a prioritized list of other nearby access points allocated to service that client, otherwise the access point sends a prioritized roaming list of nearby access points to the client that are allocated to serve that type of client. Feedback is provided by the network infrastructure enabling a network user or the network to automatically reallocate resources based on the feedback.
