RADIUS does not have a scheme for doing this. So EAP has a mechanism for
dealing with big attributes but it would be wrong to use EAP messages to
implement something like prepaid or any other application that is not an EAP
I don't think it would be a good idea to create a situation where every
RADIUS application RFC comes up with its own way of dealing with big

I don't understand what you mean here. If you meant "requirment can be met
with frametation and re-assembly that exists in RADIUS" then I have answered
