Implementation and evaluation of authorized access LAN sockets using PPPoE

The paper presents an integrated method to achieve authorized access on LAN sockets in a campus network. The key issues of our method are user authentication and user tracking. We adopt PPPoE (Point-to-Point Protocol over Ethernet) for the user authentication, and integrate the IDENT mechanism on the PPPoE server for the user tracking. We conduct performance evaluation with respect to transfer rate and CPU usage. The evaluation shows that the proposed system achieves excellent performance for its deployment cost. As a result, the proposed method could be a good candidate to add network connectivity in campus networks
