    Abstract: A method for an access point to provide immediate delivery of low-latency data packets to one virtual local area network when there are one or more associated stations operating in Power-Save-Protocol on another virtual local area network. The access point observes all the virtual local area networks to which it provides access to associated stations. The access point then determines which of the virtual local area networks contains only active stations. The access point then tracks the virtual local area network having only active stations and immediately transmits to the network incoming multicast/broadcast data packets.

    Abstract: A method for providing a superior quality of service for multicast data streams delivered over a wireless local area network. As Internet Protocol multicast data streams are received by an access point, the access point observes Internet Group Multicast Protocol registration messages to determine which of its associated stations subscribe to each multicast data stream. The access point then determines which of the multicast data streams it receives have only active subscribing stations as opposed to those data streams having at least one associated station operating in power-save mode. The access point will automatically transmit each multicast data stream having only active subscribers immediately to the associated active stations, while buffering the multicast data stream for which there is at least one associated station operating in power-save mode.

    Abstract: A method wherein an access point authenticates itself with neighboring access points and establishes secure and mutually authenticated communication channels with its neighboring access points. When an access point learns of a neighboring access point, it initiates an authentication with an authentication server through the neighboring access point. Once access points have mutually authenticated each other, whenever a station authenticates itself with a first access point, the first access point communicates the station's authentication context information, for example session key and session identifier, to each neighboring access point. Thus, when the station roams to a neighboring access point, the neighboring access point presents the station with a reauthentication protocol, for example LEAP reauthentication, and if the reauthentication is successful, communication between the station and the neighboring access point takes place immediately and no new EAP authentication needs to occur.

    Abstract: A method and system for handling roaming mobile nodes in a wireless network. The system uses a Subnet Context Manager to store current Network session keys, security policy and duration of the session (e.g. session timeout) for mobile nodes, which is established when the mobile node is initially authenticated. Pairwise transit keys are derived from the network session key. The Subnet Context Manager handles subsequent reassociation requests. When a mobile node roams to a new access point, the access point obtains the network session key from the Subnet Context Manager and validates the mobile node by computing a new pairwise transient key from the network session key.
