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 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 On 10/15/14, 1:38 PM, "Colton Conor" <colton.conor () gmail com> wrote: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?

I would thinktheseaccess switches would have some sort of stat you can count similarto autility meter reader on a house. See what it was at last month, seewhat isis at this month, subtract last months from this months, and thedifferenceis 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?
