From the developer:
RADIUS (Remote Authentication Dial In User Service) is an Internet standard defined in RFC 2865. Internet service providers use RADIUS to authenticate dial-in users. RADIUS was subsequently extended to support accounting as defined in RFC 2866.
RADIUS allows vendors to add attributes relevant to them as part of aforementioned messages.
