[c-nsp] Splitting 2 traffic streams for billing/accounting purposes

[Peter Kranz]

That's a good idea.. but no interface where I can pickup A or B only to
perform the subtraction.. Any upstream interfaces will have other customer
traffic on them..

Maybe I'm oversimplifying, but couldn't you use MRTG or similar software to
monitor the bandwidth over:

A:  The 10G link to their office
B:  Their uplink into your network

Then to separate the LAN only traffic, just subtract B from A?  I'm pretty
sure you can cook up an MRTG recipe to do just that.
