Capping issues with voucher system

[Winfield, Alister]

That depends on the network device managing the sessionŠ

Simplest case (at least its easy to implement)

The NAS has Œquotas¹ and sends a new authentication request if the quota
hits Œ0¹. In RADIUS hand out small quotas (size depends on ability to cope
with the request rate and how much over you are willing to allow a user to
go). Update real quota levels as things go along. I¹ll admin getting that
last step actually right is not as trivial as it sounds but is usually
possible.

Less simple.

Track usage using accounting data (including Interim Accounting updates).
If the usage drops to / below zero use RADIUS COA to stop all related
sessions. How you know which to stop and what information you need to
build the COA packets is implementation dependant.
