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.
