摘要： A method, apparatus and computer program product for performing location based load balancing of wireless access points and wireless switches is presented. A wireless controller (WC) receives an associate message from an Access Point (AP)/wireless switch (WS) at the WC. The WC then determines whether a preferred WC for the AP/WS is available. When the preferred WC is not available, then the WC determines if an alternate WC for the AP is available. When the alternate WC is not available, an administrator configured policy may be used that maps the AP to a specific WC. When the policy does exist then the AP is coupled to the WC according to the policy and when the policy does not exist then the WC parses the AP/WS location information for the AP/WS to determine an available geographically closest WC for the AP/WS and sends a message to the AP/WS relating to the available WC. The WC will also assign an available geographically closest WS to AP.

摘要： A switch architecture and method provides scaling through multi-level load balancing of flows across data and application processing planes. An input/output module receives a communication session flow (forward) from a client device and selects one of a plurality of data processors to process the flow. The selected data processor determines the level of processing for the forward flow and selects an application processor from a plurality of such application processors. The application processor generates a session structure identifying actions to be performed on the forward flow and transfers the session structure to the selected data processor to perform the actions on the forward flow. The application processor also predictively generates and offloads a session structure for the associated reverse flow. If the reverse session structure is offloaded to a different data processor, either the forward or reverse flow redirects packets, or is redirected, to the data processor hosting the other flow.
摘要翻译：交换机架构和方法通过跨数据和应用处理平面的流的多级负载平衡提供扩展。输入/输出模块从客户端设备接收通信会话流（向前），并选择多个数据处理器中的一个处理流程。所选择的数据处理器确定正向流的处理级别，并从多个这样的应用处理器中选择应用处理器。应用处理器生成会话结构，该会话结构标识要在前向流上执行的动作，并将会话结构传送到所选择的数据处理器，以对前向流执行动作。应用处理器还可预测地生成和卸载相关逆向流的会话结构。如果反向会话结构被卸载到不同的数据处理器，则正向或反向流将分组重定向或重定向到主机另一流的数据处理器。
