Network Parameters
Data Volume Information Transmission (bytes sent/received)
The AP’s RADIUS client implementation allows a hotspot operator to accurately track the exact number of bytes sent
and received by a subscriber based on:
•
User Name
•
IP address (Framed IP)
•
MAC address of the user (Calling Station ID)
As shown in the
, the byte counts are sent in the Accounting “Alive” and Accounting
“Stop” messages. As mentioned previously, Accounting “Stop” messages can be generated by:
•
An explicit customer logout (via ICC or by typing http://1.1.1.1/)
•
Session time-out
•
Idle time-out
•
Deleting the user from the AP’s
.
The message will indicate the type of action that initiated the Accounting “Stop”. To ensure accuracy, the AP
temporarily saves the Accounting information per user in case of a device reboot.
