摘要： A method a system and a computer program 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. Quality of packet data transmissions is improved, in particular, low-latency transmissions (i.e. VOIP transmissions and transmissions for stations in constantly active mode), since the packets for said transmissions are not buffered at the access point, but delivered immediately after reception, whereas packet for otheer transmissions (i.e. for station in Power save mode) are first stored and then delivered when requested by the corresponding stations. In particular, the method, computer program and system is implemented for low latency multicast/broadcast data packets being the destinations certain stations in different VLANS.
摘要翻译：当存在一个或多个在另一个虚拟局域网上的省电协议中操作的相关站时，用于接入点的系统和计算机程序提供低延迟数据分组到一个虚拟局域网的即时传送的方法。接入点观察其提供对相关站的访问的所有虚拟局域网。接入点然后确定哪个虚拟局域网仅包含活动台。然后，接入点跟踪仅具有活动站的虚拟局域网，并立即向网络发送传入的多播/广播数据分组。改进分组数据传输的质量，特别是低延迟传输（即VOIP传输和持续有效模式下的站的传输），因为用于所述传输的分组不在接入点缓冲，而是在接收后立即传送，而首先存储用于其他传输的分组（例如，用于节电模式的站），然后在相应站点请求时传送。具体来说，该方法，计算机程序和系统是针对低延迟的组播/广播数据包实现的，这些数据包是不同VLAN内目的地的某些站点。

摘要： 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.
摘要翻译：一种在无线网络中处理漫游移动节点的方法和系统。该系统使用子网上下文管理器来存储移动节点当前初始认证时建立的当前网络会话密钥，安全策略和会话的持续时间（例如会话超时）。成对传输密钥是从网络会话密钥导出的。子网上下文管理器处理后续重新关联请求。当移动节点漫游到新的接入点时，接入点从子网络上下文管理器获得网络会话密钥，并通过从网络会话密钥计算新的成对瞬态密钥来验证移动节点。

摘要： 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.

摘要： 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.
