基于跨AC切换实现WLAN快速拨测和拥塞控制策略研究

Research of WLAN test system and congestion control strategy based on cross-AC switching

文章介绍了当前WLAN保障中使用的拨测方法和拥塞控制手段,然后提出了一种基于跨AC切换实现WLAN拨测和拥塞控制的方法。通过提出一种跨WLAN AC的切换设备,可实现集中控制一个AP快速切换至各个AC进行拨测。利用AP拨测结果和AC日志的双重对比分析方法,对vSwitch下挂AP设备快速批量地割接至容灾AC,最大限度缩短了WLAN网络拥塞的持续时间,有效避免WLAN AC的拥塞,保障了WLAN网络质量,最终提升WLAN用户的网络感知。

The paper describes the current WLAN network security using the testing and congestion control method,then suggests a WLAN test system and congestion control strategy based on cross-AC switching.Through proposing a WLAN cross-AC switching devices,an AP can be switched to each AC for achieving the test task.The use of the double contrast analysis method based on AP testing results and the AC log,the APs connecting the vSwitch can be rapidly switched to the backup AC,which maximum shorts of the WLAN network congestion duration,and effectively avoids the congestion of WLAN AC.Ultimately the user＇s network-aware is enhanced.
