Re: Hope Virgin Media isn't blowing smoke Speed is not provisioned at the CMTS, it is sent down in a bin file to the modem. The CMTS has no control over individual modem speeds.
Unless you're loading the bin file directly from the CMTS to the modem, which is still the bin file controlling the speed of the modem.
Also, a node on a cable system is not the same as a node you just described. A node is an HFC device supplying a neighborhood, probably 150 - 200 customers, and not just Internet, the node also is where the TV signal comes over as well. This node connects to an upstream on a CMTS at 10mbit/sec. And can have its own 45mbit downstream, or share that downstream with 2 to 8 nodes depending on the CMTS configuration. |

Hrm nope since DOCSIS 1.1 speeds are provisioned at the CMTS as service flows and indeed can be and are policed there. You can even police speeds over DOCSIS 1.0 - how do you think Powerboost and STM throttling works?
I could explain how the hack works around this system but I'd rather not, let's just say Cisco have some bug fixing to do...  |
