A Network Access Server interfaces with both the local network provider, such as the telecommunications company, and the Internet backbone. NAS servers are controlled by AAA servers, Authentication, Authorization, and Accounting (AAA), which authenticate users and their logins by verifying their names and passwords. After verification by the AAA server, the NAS server can provide the user with the network and service for which the AAA server has granted authorization. The NAS server thus provides the client with the communication link between the user and the service server.
