Enhancing Mobility: The JANET Roaming Service and LIN Trial for Seamless Guest Access

The JANET Roaming Service, launched in April 2006, is a vital component of the eduroam federation, enabling seamless, location-independent network access for guest users across participating institutions in the UK. Built on a secure RADIUS hierarchy, the service enhances user mobility and simplifies guest network access through a single sign-on process. The background includes a successful LIN trial from 2005 to 2006, which involved 36 UK institutions and fostered positive feedback. The service supports collaboration among 29 European countries, Australia, Japan, and Taiwan, facilitating international roaming.

Presentation Transcript

  1. The JANET Roaming Service

  2. Covering… • Background • The Location Independent Networking (LIN) trial • The JANET Roaming service • What the service provides • Overview of the technology • How it works in practice • The eduroam federation • Parallel international effort

  3. Background • JANET Wireless Advisory Group (WAG) established May 2003 • Develop a location independent networking (LIN) infrastructure to enable networks to support guest users in a transparent & secure manner • Proof of concept tests carried out on RADIUS (Remote Authentication Dial-In User Server) hierarchy

  4. Location Independent Networking (LIN) Trial • January 2005 – January 2006 • 36 institutions in the UK • Positive feedback from JANET community • Transition to service

  5. Launched: end of April 2006 • Resilient NRPS infrastructure • Community support team fronted by JANET Customer Services • Consultancy service • Online documentation: deploying, using and supporting the service • JANET Roaming is the UK element of the eduroam federation

  6. The service • Enhances user mobility • Provides hassle free guest network access • Promotes single sign-on

  7. RADIUS Hierarchy • Organisational RADIUS Proxy Server (ORPS) • National RADIUS Proxy Server (NRPS) • International RADIUS Proxy Server (IRPS)

  8. Federated Trust Model • Participating institutions sign-up to the federation policy • Institutions trust each other to keep their user databases up to date • Network access is granted to a visitor after their credentials have been verified by their home institution

  9. For example… Authenticator (AP or switch) University of Exeter ORPS UKERNA ORPS User DB User DB Visitor’s Username louiss@ukerna.ac.uk JANET National RADIUS Proxy server (NRPS)

  10. Eduroam federation • 29 European countries plus Australia, Japan and Taiwan • Based on the same technology (RADIUS) • IRPS hosted in Denmark and the Netherlands on behalf of TERENA • Enabling international roaming • http://www.eduroam.org/
