Re: I wonder how the count the traffic

said by bugabuga:

I wonder if they will be counting all inbound traffic that gets delivered, or just passes their border router.
I.e. if you turn the modem off while someone keeps sending packets to "your" address, will that still have counter spinning or if the modem needs to be on, and if router manufacturers will start offering a power port to bring the cable modem up/down on demand

That's not necessarily true. Routing doesn't change. IP address linked to modem's MAC address doesn't change. Traffic may still come down to the node etc
Unlike dial-up, cable modems have quite consistent IP addresses

I would expect it to be tied into the MAC address of your cable modem.

Here on Bresnan, each subscriber gets 2 IPs so to speak. One is assigned to the modem directly and is inside of Bresnan's internal network with a private IP in the 10.253.x.x range. The other is assigned to the device behind the modem and is a public IP in the 69.144.x.x range.

If they were to monitor only the 69.144.x.x IP, that should eliminate any local chatter from the modem to the CMTS and vice versa.

They could probably use something as simple as SNMP to read the stats going over the Internet side.
MRTG, Cricket, etc. could all do the function fairly easily.
The longest part would be implementing (documenting, NOC, process, etc.)
