For GPON and Ethernet it's just SNMP counters.

So it looks like DOCSIS cable has a great solution with IPDR, but what
about DSL, GPON, and regular Ethernet networks?
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

I see in past news articles that cable companies are inaccurately
calculating customers data usage for their online GB of usage per month. My
question is how do you properly determine how much traffic in bytes a port
passes per month? Is it different if we are talking about an ethernet port

Folks, use sflow with rrdtool!
Quite awesome handy

Don't forget that between your port on your DSL/Cable modem and the actual
port they may be monitoring
IPDR under DOCSIS and generally RADIUS or TACACS(+) for DSL. Unclear
personally about fiber/FiOS deployments (never been near enough to know)
Flow (sflow, nflow, ipfix, etc) generally doesn't scale and is woefully
inaccurate.

This all becomes even more complicated when some traffic isn't counted
(Eg. free facebook) on a given service which generally then
necessitates the need for some level of flow-based accounting, even if
it's just collecting flows for the free traffic to subtract from the
port counters. I can
