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.

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 on a cisco switch vs a DSL port on a DSLAM for example? I would think these 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. Why are the cable companies having such a hard time? Is it hard to calculate data usage per port? Is it done with SNMP or some other method? What is the best way to monitor a 48 port switch for example, and know how much traffic they used? https://gigaom.com/2013/02/07/more-bad-news-about-broadband-caps-many-meters-are-inaccurate/
