Eduroam is a Wi-Fi roaming system which allows a user of a domain to access wireless resources in another domain with the unique credential of the user managed in the original domain. Eduroam employs a hierarchical tree structure of RADIUS servers to provide a scalable authentication procedure over wide area networks. However, the tree structure of RADIUS servers causes long latency of remote authentication procedures, and the single point of failures can be issued. In this paper, we propose a flat layer approach to build a network of RADIUS servers in order to reduce the delay of remote authentication procedures and eliminate the concern of the single point of failures. In the flat layer approach, each RADIUS server knows the information of all the other RADIUS servers through a domain mapping table. The domain mapping table is updated whenever the membership of the network of RADIUS servers is changed. To make the updating operation of domain mapping tables more efficient and faster, DHT based broadcasting approach is used. Through an implementation based evaluation, we show that our flat layer approach is efficient and viable in practice.
