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.

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.

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.
