Abstract:
The present invention relates to group restart in switched ATM networks. In accordance a method of one embodiment of the present invention, a first network switch receives a message (e. g. , a call setup message) at one of a plurality of interfaces to the first network switch. This first network switch reads data (e. g. , a group identifier) contained in the message. In response, the first network switch generates first modified data as a function of both the data of the message and first interface identifier data. The first interface identifier data corresponds to or identifies the interface at which the first network switch received the message. The first network switch replaces the data in the message with the first modified data thereby creating a first modified message. Lastly, the first network switch outputs the first modified message from another of the plurality of interfaces.

Abstract:
In one embodiment, a method for processing encrypted wireless station data at a network device includes receiving from an access point, one or more frames comprising wireless station data fragmented into a plurality of encrypted protocol data units. The frames are configured to identify the encrypted protocol units associated with the wireless station data. The method further includes decrypting the encrypted protocol data units and forwarding the wireless station data. An apparatus for processing encrypted wireless station data, a method for transmitting encrypted multicast data for a wireless client, and a method for processing encrypted wireless station data at an access point are also disclosed.
Fast Handoff For Wireless Devices In A Wired-Wireless Network

A method and apparatus for handoff of a wireless client from a first network device to a second network device in a wired network are disclosed. In one embodiment, the method includes receiving data from a new wireless client at the second network device and transmitting a request for a route update for the new wireless client to the wired network. Prior to network convergence for the route update, data traffic for the new wireless client is received from the first network device and forwarded to the new wireless client. Context information for the new wireless client is transmitted from the second network device to other network devices in a proximity group of the second network device.
