i gave up on per-customer interface accounting, didn't scale for me.
Thats a very bold statement. A what point (what metric?) did you feel that this method didn't scale?
i'm not super-duper, but i'm tier2 and the bulk of my business is wholesale (the basic service is a connection and transit, nothing else). most of my customers are ethernet connected, and some customers share an interface. i got into this before it was cheap to do 802.11q switching, so my billing system needed to deal with multiple customers on a single ethernet.
NAC is no super-duper tier-1 (I had to throw that in), but we do monitor
1400 interfaces every 5 minutes, 100 or so at more than 105 mb/s
i don't have near that many interfaces. however, the rollover issues were starting to become apparent. fortuneately with the BSD and cache flow stuff, i get 64bit counters.
we've since moved to cisco, and, well, now i have cache flow stats which are parsed into customer subnets.
Eeek. Relying on flow-stats? Yikes.
