Re: Cox...
What makes you think earlier versions of Docsis are uncapable? |

1 edit | Last time I checked the capping(at least the current type) was being done based on the cable modem's Mac address on the server (node) side. So it does not matter what version of Docsis the modem is using, they tally and control the cap from the far side of the modem. |

So it does not matter what version of Docsis the modem is using, they tally and control the cap from the far side of the modem. Imagine there was a modem, and you could flash it to a custom firmware. This custom firmware allowed you to disable SNMP (so the ISP couldn't even query your modem), download a config file (which has capping information) over ethernet from your own TFTP server (host a 0/0 config) and allow you to change the HFC mac address to whatever you want.
Say you clone some other poor guys mac address 500 miles away from you. Although not impossible to catch its extremely difficult which is why many people do it and it is possible and people rarely get caught.
(Please don't think this is an admission from me that I uncap).

Chugging along on 2x 6016/768k DSL Extreme DSL lines and one 6016/768 ATT DSL DIrect line as well as one 10mb/1mb Charter cable line for a combined total of just over 26 meg download and 3 meg up (after overhead). yay! |

What you are describing is the cap on the speed of the modem. This is not the type of cap we are talking about. The current cap is on capacity (gigs downloaded per month). This capacity cap is tracked on the ISPs end and not the modem. Yes, you could circumvent this cap by changing the Mac of the modem to another valid Mac in the system(thus running up his tally instead of yours), but this would not be dependent on the Docsis version the system was running on(it is irrelevant). After the cap is reached the throttling is done on the ISPs side and generally not by changing the speed setting on the modem. Other than a Mac address the modem is essentially not involved. The ISPs are well aware of Mac spoofing. |

The ISPs are well aware of Mac spoofing. I was always taking about speed uncapping not a bandwidth cap. Charter does not limit the bandwidth, they don't have a 'bandwidth cap'. I was originally responding the the comment about they will probably only have it in FIOS areas.
You are correct that bandwidth caps could be circumvented by hijacking other peoples mac addresses. I am not sure what you mean by throttle after a cap is hit. Who has caps that throttle you when they are hit? Also changing to a different mac address would likely circumvent this as well assuming they are not throttling everyone on your node. |
