Re: I wonder how the count the traffic 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 |

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.) |
