Appendix D. RADIUS Accounting
This section is trying to organize the basic configuration with RADIUS server to work with VSA.
The aim is trying to control the maximum usage (upload; download or upload + download traffic)
of clients in each session.
This VSA will send from RADIUS server to gateway along with an Access-Accept packet. In
other words, when the external RADIUS server accepts the request, it will not only reply with an
Access-Accept and it will also carry a maximum value in bytes that each user is allowed to
transfer. This value may be the maximum upload traffic; download traffic or the summation of
each user's download plus upload traffic in bytes. Gateway will check this value every minute, if
the user is reached this value, gateway will stop the session of this user and send a "Stop" to
RADIUS server.
