Radius server is a type of server which is used for authenticating the users who are trying to access the network. It was originally developed by Livingston Enterprises, Inc in 1991. Radius server is used for authenticating and authorizing the remote users who are trying to connect to a network. Radius server is also used for storing the user account information and user preferences.
History of Radius Server
The history of the RADIUS server began in 1991 with the release of the Livingston Portmaster, one of the first commercial dial-up servers. The Livingston Portmaster was designed to work with the Remote Authentication Dial-In User Service (RADIUS) protocol, which was developed by Livingston Enterprises, Inc. to provide centralized authentication, authorization, and accounting (AAA) services for dial-up users.
In 1995, the Internet Engineering Task Force (IETF) standardized the RADIUS protocol in RFC 2138. Since then, the RADIUS protocol has been widely adopted by ISPs and network equipment vendors. Today, RADIUS servers are an essential part of many network infrastructure deployments, providing AAA services for a variety of devices and services, including wireless access points, VPN servers, and VoIP systems.
