Well, not to be nit-picky, but that wouldn't strictly be averaging, then. To get back to the question at hand, another scheme that I'm seeing more prevalent lately is dual-bin, where local traffic is flat-rate, and international traffic is measured-rate (i.e. billed per-bit). That's relatively easy to do in a simple satcom-up sort of network, since you just bill by netflow accounting on the satcom interface. There's been a really good discussion of these sorts of billing methods going on on the NordNOG list over the past two weeks, and we'll be having a panel discussion on billing methods at the NordNOG meeting next week. -Bill
