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?
