The initial group charter was to properly specify and “clean up” the protocol without adding new features or creating changes. The result of this work is found in the initial RADIUS RFC, RFC 2039, which was issued in January 1997. It was followed by an informational RFC that speciﬁed RADIUS accounting as an extension to the RADIUS RFC. The original RFC was superseded by an updated version (RFC 2865) in 2000. The combination of higher-speed line encodings, the evolution of broadband services, and increasing subscriber management needs spawned a market in the mid- to late 1990s to service the growing demand for broadband from service providers and telcos.
Other key technical milestones are too numerous to mention; however, the approach has always been the same and is clear in its goals: Focus on the work most needed by the industry, converge on a single agreed-upon solution, and standardize this with Technical Reports that are voted on by a membership ballot. The Forum currently has more than 200 members who meet four times a year at week-long meetings. These meetings continue to be invaluable as telecos, service providers, and equipment vendors thrash out best practices and architectures that enable rollout of new networks and services that are scalable, timely, and economical for all.
