This document describes how to install and configure the Radiator policy and charging support for Radiator AAA Server from Radiator Software.

Diameter is an AAA (Authentication, Authorisation, Accounting) protocol commonly used by, but not limited to, telecommunication systems. Diameter protocols are called applications and use the Diameter base protocol. For example, Diameter Credit-Control Application defines the additional command codes and attributes required for supporting real-time credit-control. See RFC 6733 for the Diameter base protocol. Diameter applications supported by Radiator are introduced later in this reference manual.

RADIUS is the de facto AAA protocol for authenticating users and for recording accounting information. It is commonly used by Wireless Access Points (APs), Terminal Servers, or NAS (Network Access Server) whenever a user logs on and off network access devices or dial-up Internet service. It is supported and used by most vendors such as Cisco, Ericsson, Huawei, Juniper, Ruckus, Aruba, Alcatel-Lucent and others. See RFCs 2865 and 2866 for more details on the RADIUS protocol.

Radiator is a highly configurable and extensible AAA server that allows you to easily customize and control how you authenticate users and record accounting information.

Radiator runs on most Unix, Linux and Windows hosts. It is written entirely in Perl, and is therefore highly portable. Full source code is supplied, so you can alter the behaviour of Radiator's internals if you need to. Detailed list of supported systems and installation requirements are available in the Radiator reference manual https://files.radiatorsoftware.com/radiator/ref.pdf
