What is radius server?

Remote Access Dial In User Service (RADIUS) is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for computers that connect and use a network service. RADIUS servers use the AAA concept to manage network access in the following two-step process, also known as an "AAA transaction". AAA stands for “authentication, authorization and accounting”. Authentication and Authorization characteristics in RADIUS are described in RFC 2865 while Accounting is described by RFC 2866.
