I know of two: JANET (the research network in Great Britain) uses NetFlow to charge connected organizations (universities etc.) for their use of the transatlantic links: http://bill.ja.net/ And we (SWITCH, the Swiss research network) do the same: http://www.switch.ch/lan/stat/fluxoscope/ Unfortunately I don't know much about the software used by JANET, but I'm pretty sure that in both cases custom software is used. There are several producers of commercial IP billing software, such as Xacct, Apogee, and Rodopi, who claim to support NetFlow. > To demonstrate that it would work though, there's a presentation on > a host-based rate-limiting system based on NetFlow here: > http://www.ncne.nlanr.net/training/techs/2001/0128/presentations/200101-kline1_files/v3_document.htm > Also, the Univ. of Texas at Austin has a host-based quota system > (a.k.a.
