摘　　要：为了提高WLAN(无线局域网)AC(接入控制器)对大流量网络数据的处理效率,对交换芯片ContentAware(内容识别)机制进行了研究与测试,对比软件实现的负载均衡机制的效率,提出了一种实时控制交换芯片的负载均衡实现机制。该机制分离了数据面与控制面,均衡了业务数据,实现了负载均衡的实时控制,避免了软件机制使用单独负载板背板接口的容量上限,提高了多板AC的吞吐量和稳定性。In order to improve the processing efficiency of Wireless Local Area Network （WLAN） Access Controllers （AC） for large traffic network data, this paper studies and tests the ContentAware mechanism for the switching chips. Compared with the load balancing mechanism for software implementation, it presents a load balancing mechanism based on real-time control of switching chips. It separates the data plane and control plane, balances the service data, implements the real-time control of load balancing and avoids the backplane interface capacity limits of the separate load boards used in the software mechanism, effectively improving the throughput and stability of the multi-board AC.
