I wonder if how such a "package" can be implemented,

1. Unlimited rate normally 2. But when downloaded packets exceed certain defined figure, download rate is trottled.

Ensure that the NAS can dynamically change download rate. If it can't, then no amount of work on the RADIUS server will help.

One way I could think of is to run a batch job which work out per user octet usage and then set the attribute WISPr-Bandwidth-Max-Down accordingly. But this will have to be per day basis, it might be too late ( after the subscriber have over abused it ).

Is there way such a thing can be implemented inside radiusd so that everything happens on the fly ?

You said it yourself... the server is receiving accounting packets. You can check *then* whether or not the user is over their quota.

In fact, that's *exactly* the use case for the CoA functionality in the server. You can check for bandwidth usage, and if the user is over the limit, send a CoA or Disconnect packet to the NAS.

NASes from major vendors are now starting to implement support for CoA and Disconnect packets.

Sorry I have quite an idiot here. I have been reading everything radius 2.1.4, but I don't see how this is integrated into the radiusd server. Am I missing anything ? Is this to say that upon receiving accounting packets, spinning off a check and if the condition is met then send CoA reply via radclient is the way to go now ? Best regards.
