[c-nsp] NetFlow for Bandwidth Billing

[TCIS List Acct]

We are a Co-lo provider looking to improve how we do usage-based bandwidth 
billing on a per IP/subnet basis.  We can't do SNMP monitoring per-port (we 
exclude local LAN traffic, traffic between our two Data Centers, etc), so we are 
considering doing bandwidth billing via NetFlow from our 72xx core routers. 
What are the pros/cons of using NetFlow for usage-based billing?  I've seen some 
discussion regarding NetFlow's accuracy/completeness, so any advice would be 
appreciated.

TIA.
