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?
If you're measuring per month, there is no reason you can't use SNMP, poll that 64bit counter once per day or something, and then add the values up each month. It'll be accurate enough. SNMP isn't sampled, if you poll the IfOctet counter, it just counts upwards and if you're not worried about the switch rebooting, you could poll it once per month and be accurate. I'd say polling it once or a few times a day protects enough against that.
