Abstract:WiFi Access Points (AP) are widely deployed in public places such as schools, shopping malls, and airports to meet the network access demands of users at any time from any location. However, managing a large-scale WiFi network is still a difficult problem to be solved, and the diversity of devices makes it difficult to provide centralized access management in WLAN. Meanwhile, due to the promotion of various new network services and applications, the problem of low utilization of network resources in traditional WLAN and unbalanced load of access points is becoming more serious. In this study, we adopt the idea of Software-Defined Network (SDN) and apply the Protocol Oblivious Forwarding (POF) technology in the WLAN network. We propose a deep programmable WLAN architecture to realize centralized access management. Moreover, considering the factors such as Received Signal Strength Indicator (RSSI) and real-time network traffic, we design a wireless AP access management mechanism based on MultiPath TCP (MPTCP). It can make full use of the bandwidth resources of each AP, avoid the continuous transmission of data on the congested path, and hence achieve the balance of work loads of substrate APs.
