said by joeyconcrete :What I'm wondering is there a way whereby you can actively disconnect a session by sending a "message" of some sort from the RADIUS server. Almost like a "stop" message sent to the access-device. The less elegant solution of disconnecting their session very xxx hours would work - I'm presuming a session-timeout will drop the PPP connection entirely? While I've seen Radius bent into some strange shapes, usually this is done when the session is started. That sounds crazy, but think of RAS gear... A user dials in, and the radius server OK's him. Along with that information, it may also specify the user has an idle-timeout of 10 minutes, a session-timeout of 8 hours, etc. So in that case, lots of the "counting" is really done on the radius client. Sometimes the radius server and the client may both be doing some neat stuff that in combination leads to something like "this user can have X bytes/month".
Now how radios implement this, I have no idea. My day job is totally wired.  |

| Wired/Wireless, I guess ultimately it ends up at a concentrator. After scanning the web, it appears its only possible using "special" implementations or specialist software. For example, BT's broadband in the UK limits you to 10gb @ 512kb, then once you're quota is exceeded your speed is throttled to 64k. I'm guessing this is using some specialist kit as opposed to a simple concentrator/RADIUS pairing. Google seems to throw up companies like Allot and Packeteer - they have fancy things like policy managers etc - but all look very expensive! |
