Service description
The purpose of eduroam (education roamingeducation roaming) is to provide secure, worldwide roaming access service for the international research and education community.
...
GÉANT operates the confederation-level service for members of the European eduroam Confederation, which is formed of autonomous roaming services who agree to a set of defined organisational and technical requirements by signing and following the eduroam policy declaration is based on the eduroam service definition. The confederation’s goal is to provide a secure, consistent and uniform network access service to its users.
Users
eduroam (first-level) users are National Roaming operatorsOperators, that are responsible to operate eduroam service on a National national level for their country. Up to date list of eduroam users is available at the eduroam monitor site.

The European eduroam service is built hierarchically. At Confederation-level service is at the top level sits the confederation-level service, which , and it provides the confederation infrastructure required to grant network access to all participating members of the eduroam service together with a set of supporting services. This confederation service is built upon the national roaming services, operated by the national roaming operators (NROs – in most cases, NRENs). National roaming services make use of other entities, for example, campuses and regional facilities. eduroam service delivery model is presented in the following picturepictures.
|  |
The European service is governed by the eduroam Steering Group (SG), while day-to-day operations are carried out by the eduroam Operations Team (OT).
In addition to operating the service’s basic technical infrastructure, the GÉANT eduroam team also delivers a supporting services suite to facilitate the widespread deployment of eduroam. This suite includes a central :
- eduroam database (eduroam db) with information about participating institutions, https://monitor.eduroam.org/
- monitoring & metering tools (f-ticks)

Technology infrastructure
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.
Full explanation of Complete explanation of technology infrastructure is provided at in in the eduroam Service Definition.
The following table is a list of products and resources used to deliver main functionalities of the eduroam service.
European Top-level RADIUS Servers (ETLRS) for the European Confederation are operated by SURFnet (Netherlands) and DeIC (Denmark). Top-level RADIUS Servers are deployed using Radiator software.

Service main element | Description | Technologies used in delivery | Access URL |
|---|---|---|---|
| (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. |
