Hello Alan,
Why not just update the users credit when the session is closed?
Good question. The short answer is to charge as soon as possible.
Store the last "session length" for a session. If the current packet
has a smaller session length, ignore the packet. Otherwise, look at the
difference between the stored session length, and the session length in
the current packet. Use that time for billing, rather than the time you
received the packet.
That's the way it's implemented right now. Thanks
2. Is it a correct behavior of a NAS to store accounting information on
it's internal disk if it can't get acknowledgment for accounting
request/s and resend it later?
Yes.
How much time can it keep the data? I don't think it's a good idea to
resend the data after several hours.
Best Regards,
George
