The reason is the cost of system building. As there
are a lot of broadband subscribers, if we want to
corelate subscriber with web site they visit we have
to make Radius allocate a fixed IP to a special
subscriber. Netflow based accounting is costy and we
could not guarantee its accuracy.
In fact, we only need to identify a small set of IPs
which should not be considered in accounting.
