Abstract

A flexible access control mechanism with user authentication is required for campus wireless LAN roaming. In general, VLAN tagging and firewall are adopted to realize it. However, the scalability of the conventional VLAN mechanism is low for a large system. An OpenFlow-based system was proposed to solve the problem. In this paper, we point out some limitations of the conventional system, and propose a new access control system. We also implement our system and demonstrate that it works correctly with acceptable server load and high usability.
