Current wireless enterprise networks pose a user access management challenge. That is, an network should provide service to diverse devices whose resource allocation policies be treated differently according the company policy. Software-defined (SDN) is suitable candidate meet challenge due its centralized and dynamic control features. Based on OpenFlow protocol, which primitive realize software-defined network, this work implements bandwidth slicing technique commercial WiFi AP. The operating system in AP flashed into OpenWrt linux enable client function. Experimental results show that users different groups experience amount of share proportions can adjusted dynamically real time. Moreover, illustrative video quality presented groups, verifying applicability technique.
