There's no correlation between PPPoE and RADIUS. Many (if not all) BRAS/BNG platforms will support RADIUS based accounting for IPoE sessions.
The majority of accounting is done that way; with outliers using some other mechanism (Diameter; proprietary vendor billing solutions; flow based platforms; or counters elsewhere on the network). WiFi in my experience also typically uses a RADIUS based approach, although it can depend on the deployment context.

It was mentioned that DSL uses radius, but most new DSL systems no longer use PPPoE, so I don't believe radius is a viable option. What about Wifi Access Points? What would be the best way to track usage across these devices? On Wed, Oct 15, 2014 at 3:33 PM, Livingood, Jason < jason_living...@cable.comcast.com> wrote: > There are lots of ways to do it.
