What is RADIUS?

The RADIUS (Remote Authentication Dial In User Service) protocol has been traditionally used to authenticate and provision dial up clients. Additionally it performs accounting services for the same clients. RADIUS services fall under the category of AAA (Authentication, Authorization, and Accounting).

This protocol is the de facto industry standard for these services.

Many modern applications use the accounting function for Mobil-IP and VOIP (Voice over IP).

Software can use the RADIUS protocol to authenticate, provision, and provide accounting services for software applications.

What is a RADIUS Server?

A RADIUS server provides a single point authentication and accounting services for dialup systems, wireless LANs, and applications.

It's the standard method of integrating a diverse collection of authentication methods into one server. It does this by providing a highly standardized way for any RADIUS client in any device or application to use diverse back end authentication systems in a secure manner.

A RADIUS server provides a common front end to any number of back end services (LDAP, directory services, databases, flat files) that provide a store of names, passwords, policy and provisioning services.

Most RADIUS servers on the market are turn key solutions. The AXL RADIUS server is offered is to you who find turn key solutions insufficient or inefficient and wish to design their own back end systems. The AXL RADIUS server also embeds well in other applications.
