摘要 基于软件定义网络将网络的控制平面与转发平面分离,并提供开放的可编程接口等特点,提出一种基于SDN的AP负载感知的切换算法,以减少网络中频繁切换并使AP间负载相对均衡。该方法利用SDN集中控制功能,实时监控AP的网络状态信息,并由控制器判断AP负载状态和预测终端运动状态来辅助切换过程。实验结果表明,该切换方法可以减少切换次数和平衡AP间的负载,保证用户网络服务质量。

英文摘要 Based on the software-defined network that separates the control plane of the network from the forwarding plane and provides an open and programmable interface, this paper proposed a handover algorithm based on SDN for AP load sensing to reduce frequent switching in the network and made the load between AP relatively balanced. The method used the centralized control function of SDN to monitor the network status information of the AP in real time and the controller assisted the load status of the AP and predicted the terminal movement status to assist the handover process. The experimental results show that this method can reduce the switching times and balance the load between AP to ensure the quality of service of users.
