摘要： Supporting idle stations in an IEEE 802.11 wireless distribution system. When a station in an IEEE 802.11 wireless distribution system (DS) enters the idle state, it is not associated with any access points (APs) in the DS, Prior to entering the idle state, a station may establish filters indicating what traffic it wishes to receive. These filters are sent to a server in the DS. When a station goes idle, it is associated with a paging server in the DS, which buffers all received for the idle station, and initiates paging of the idle station when such traffic meeting filter criteria is received. When the station exits the idle state by reassociating with an AP in the DS, the server is notified, and forwards the buffered traffic to the station through its AP. The server may be implemented as a process running in a controller or portal in the DS.

摘要： Overlaying a Wireless Macro Cell architecture on a Micro Cell network. WLAN MAC Address Translation (WMAT) is used to translate BSSIDs from the BSSID used to initialize a radio in an access node and identify communications between the radio in the access node and a controller, and the BSSID used over the air for Macro Cell operation. WMAT is used for transmit operations, translating the BSSID of outgoing packets to the Macro Cell BSSID prior to wireless transmission. On the receive side, packets undergo WMAT and transmission to the controller if the STN MAC address of the sender is in an ACK table associated with the radio, or the packet is one of a predetermined type. The ACK table is managed by transmit operations, and by control commands from the controller.

摘要： In one embodiment of the invention, a wireless network is adapted with a wireless network switch in communication with a plurality of access points, which are in communication with one or more stations. Coupled to the access points over an interconnect, the wireless network switch is adapted to receive a DEAUTHENTICATION message sent by one of the plurality of access points in the same coverage area of the station so as to detect the DEAUTHENTICATION message and to block communications between the plurality of access points and the station in response to determining that the DEAUTHENTICATION message is invalid.

摘要： According to one embodiment of the invention, a network device comprises a first processing element and a second processing element. The first processing element is adapted to handle an authentication handshaking protocol, such as the SSL/TLS Handshake, and upon receipt of a Client Key Exchange message, passes control of the authentication handshaking protocol to the second processing element. The second processing element completes the authentication handshaking protocol.

摘要： Automated generation of certificates from a Certificate Authority through the use of an Enrollment Agent. Devices needing certificates generate the necessary keys and package public key information with other identifying information about the device and send this information to an Enrollment Agent. The Enrollment Agent takes this information and submits it on behalf of the device to a Certificate Authority, managing the interaction with the Certificate Authority on behalf of the device. The Certificate Authority signs the request, returning a certificate to the Enrollment Agent. The Enrollment Agent packages the certificate along with the other certificates needed to establish a chain of trust and returns these to the device. Certificates may be stored in the device in flash memory. The process is secure as long as the communications path between the devices and the Enrollment Agent is secure; a secure VPN or HTTPS: connection allows the devices and the Enrollment Agent to be in separate locations.

摘要： Improved distance estimation of a selected transmitter. An improved distance estimate from a target transmitter to a receiver is produced by assessing the target transmitter to determine transmit power, and combining this information with a propagation model, received signal strength, and reference signal strength indications. Target transmit power may be assessed through knowledge of the target device or device class, and/or transmit power reporting features of target wireless networks. The assessment may be made through looking up reported target device characteristics in a database, making inferences based on target device characteristics, or through standards-based diagnostic and/or reporting mechanisms.

摘要： Distributed load balancing in wireless digital networks. In a network having a plurality of access nodes with at least one wireless client connected to a first access node, the client is encouraged to move to a different access node by reducing the apparent signal strength of transmissions from the access node to the client. Apparent signal strength can be reduced by reducing transmit power, by using beam forming, antenna switching, or a combination. Other access nodes may send unsolicited frames, such as probe response frames to the client, encouraging the client to move.
