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_Livingood@cable.comcast.com> wrote:
There are lots of ways to do it. Cable uses IPDR, which is baked into DOCSIS standards. http://en.wikipedia.org/wiki/Internet_Protocol_Detail_Record

So based on the response I have received so far it seems cable was a complicated example with service flows involved. What if we are talking about something simpler like keeping track of how much data flows in and out of a port on a switch in a given month? I know you can use SNMP, but I believe that polls in intervals and takes samples which isn't really accurate right?

Folks, use sflow with rrdtool!
Quite awesome & handy

on a cisco switch vs a DSL port on a DSLAM for example? I would think

access switches would have some sort of stat you can count similar to a utility meter reader on a house. See what it was at last month, see what is is at this month, subtract last months from this months, and the difference is the total amount used for that month.
Assume a 20mbit connection. How many times can this roll over a 32 bit counter in a month if it's going full blast?
