Deployment of AAA Infrastructures in IPv6 Networks

AAA infrastructures based on RADIUS protocol are being widely used in current IPv4 networks in order to control and manage end-users belonging to one administrative domain. In this way, these infrastructures will be a key component to control future IPv6 end users. Furthermore, each end user could belong to different domains, so in order to give services to this user from a different domain, roaming must be supported. This paper shows several scenarios deployed in a real IPv6 network (Euro6IX project network) based initially in RADIUS. Additionally it shows other more advanced scenarios where next generation AAA infrastructures based on Diameter protocol, were deployed and tested in the same IPv6 network.
