The confederation infrastructure relies on a distributed set of AAA servers. The current configuration uses RADIUS as the AAA protocol. There are various transport protocols to carry RADIUS payloads, as of May 2012, the following protocols exist: RADIUS/UDP, RADIUS/TCP, RADIUS/DTLS and RADIUS/TLS. eduroam supports transport over RADIUS/UDP and RADIUS/TLS, and recommends the use of RADIUS/TLS. Routing of RADIUS messages, independently of the transport used, is implemented in two ways: a baseline routing model, based on a hierarchy of RADIUS servers, and a dynamic-routing model, based on DNS service discovery. The dynamic-routing model is only supported over RADIUS/TLS.European Top-level RADIUS Servers (ETLRS) for the European Confederation are operated by SURFnet (Netherlands) and DeIC (Denmark) as part of eduroam OT. Top-level RADIUS Servers are deployed using Radiator software.
Complete explanation of technology infrastructure is provided in the eduroam Service Definition.
The following table is a list of products and resources used to deliver main functionalities of the eduroam service.

|---|---|---|---|
| (two) European Top Level Radius servers - ETLR | Each server has a list of connected, federation top-level domains (.nl, .dk, .hr, .de etc.) serving the appropriate NRENs. The servers also maintain exception rules for domains whose federation membership is not immediately identifiable in the realm (typically gTLD realms such as ’.edu’, ‘.eu’, ‘.net’, etc.). The servers accept requests for the federation domains they are responsible for, and subsequently forward them to the associated RADIUS server for that federation, and transport the response (i.e. result of the authentication request) back. |
