About the AAA Applications
The AAA test applications provide comprehensive Authentication, Authorization, and Accounting (AAA) testing in a 3G environment using either the RADIUS or Diameter protocol. The Network Access Server (NAS) and AAA servers exchange the messages necessary to negotiate mobile user connection requests, authenticate the mobile user, assign an IP address to the mobile user, determine the service that will be supplied to the mobile user, and maintain accounting information. A successful message exchange is referred to as a transaction. A general AAA access model is shown in the diagram below.
The test cases provided with the AAA applications enable you to test both a AAA server and a NAS. The basic capability of the AAA test applications, the AAA Server Nodal test case, tests a AAA server by generating traffic from an emulated NAS towards the AAA server, and listening for and interpreting the responses.
With the optional AAA Server Node test case, you can include an emulated AAA server in a test session with a test case from another application in order to test a NAS SUT. The AAA emulator provides authentication services for the NAS, including optional IP address allocation, and responds to accounting messages sent from the NAS.
