Figure 139 Implementation process of traffic accounting
The following details the traffic accounting procedure:
1 After a user passes the 802.1x authentication, the user goes online successfully.
2 The authenticator device acquires the online IP address of the user and starts to
account for the traffic of the user.
3 The user accesses networks and traffic is generated.
4 The traffic collection module sends the user’s online traffic to the traffic
accounting module (LS81VSNP I/O Module).
5 The traffic accounting module performs traffic statistics based on traffic group,
and generates traffic accounting statistics, which reflects the accumulated amount
of the traffic generated since the user gets online.
6 The traffic accounting module periodically sends update traffic accounting
statistics to the accounting server.
7 When the user goes offline, the authenticator device sends the total traffic
amount to the accounting server.
8 The accounting process is over for this user.
