RADIUS Remote Authentication Dial-In User Service. An AAA protocol that allows a
server to store all of the security information for a network in a single, central
database. The server stores and manages end-user information so that it can
authenticate the end-users. The server also maps end-users to the services that
they are allowed to access. For more information, see RFC 2865 at http://
www.ietf.org/rfc/rfc2865.txt.
RADIUS server A common type of AAA server. The RADIUS server authenticates end-users,
using protocols such as PAP, CHAP, and EAP. If the end-user passes authentica-
tion, the server authorizes access to the network based on policies such as
valid access times. The server can also authorize the end-user for a specific
level of access by sending dynamic settings for the NAS to enforce. As an
accounting server, the RADIUS server can also be notified when a session
starts and stops.

bandwidth a connection type can use.
