6.6. Further Resources

The original IETF working group for RADIUS concluded its work back in July 2000, after producing and revising many standard track and informational RFC specifications. Some of these specifications have been mentioned in the text so far and some are listed below:

  • RFC 2548 Microsoft Vendor-specific RADIUS Attributes (Informational)

  • RFC 2809 Implementation of L2TP Compulsory Tunneling via RADIUS (Informational)

  • RFC 2869 RADIUS Extensions (Informational)

  • RFC 3576 Dynamic Authorization Extensions to RADIUS (Informational)

The reader is also strongly encouraged to follow the work of the RADEXT working group for more information on the progress of RADIUS specifications.

6.6.1. Commercial RADIUS Resources

Commercial RADIUS servers vary in price and capability as well as type of platform. Both software only and software/hardware combo platforms can be found. For instance, Funk Odyssey server, which includes 25 software licenses can run below $3000, while more sophisticated steel-belted servers from the same company are priced over $7000. RADIUS server providers are abundant, many of which support a wide range of network providers, such as ISPs, Wi-Fi, GPRS, and CDMA providers with a wide range of features, such as EAP/LEAP/MS-CHAP/accounting and interaction with a variety of mail and web servers and databases.

To name, but a few RADIUS server providers: Aradial, Bridgewater Systems, Cisco, Funk, IEA, and Interlink.
