Abstract

The invention discloses a campus network WLAN roaming access authentication system and method based on SDN. The system includes an access and data forwarding device and a control authentication device. The access and data forwarding device includes: an access point AP, an OpenFlow switch, a wireless interface The ingress gateway; the control and authentication device includes an SDN controller and an AAA authentication server. The method includes sending an authentication request frame of the terminal to an OpenFlow switch, and the switch forwards it to an SDN controller for authentication, and if the SDN controller fails authentication, the SDN controller interacts with an AAA authentication server to forward the authentication request frame to the AAA The authentication server performs authentication and forwards the authentication result information to the access point AP via the SDN controller and the OpenFlow server. The authentication access mode of the invention shortens roaming access time and improves roaming service quality.

Description

technical field [0001] The invention relates to a campus network WLAN roaming access authentication technology, in particular to an SDN-based campus network WLAN roaming access authentication system and method. Background technique [0002] With the rapid development of mobile smart terminal devices, users use mobile smart device terminals more and more widely, and wireless network access has become the most extensive access standard for Internet access. Nowadays, the deployment of a wireless local area network (Wireless Local Area Network, WLAN) based on the IEEE802.11 standard can be seen everywhere. If a mobile terminal wants to access WLAN to connect to the Internet, it must first complete access authentication. Access authentication plays an important role in WLAN. The basic principle of WLAN access authentication is: the network management server maintains the basic information of registered users. Information includes: user account, user password, user age, user gend...
