I am sure Comcast never worried about that for internal use, especially with a STILL rarely enforced 250GB cap. But you are right, those who obsess about caps and who will want to use 249.99 GB/mo just to make a point will threaten lawsuits over the issue.

| | | | | | I'll try on docsis 3 with dd wrt. Comcast hasn't gone gestapo on people yet anyway, so isn't this a non-issue for now?
I use Outlook to pull my mail, but I had the unfortunate experience of trying their Smartzone mail...man, that's horrible. I would hope they'd fix that too.

additionally, 3 gigs is *not* going to put you on the "comcast black list". if you are using 253 gigs a month, they aren't going to punish you. while it is a valid concern for the most accurate bandwidth usage/count, its not going to be a deal breaker.

I don't disagree with your conclusions. Just pointing out that the cable modem is seeing this overhead traffic and Comcast may or may not be counting it. And I avg about 10 to 15 GB/mo, so I am not worried about it at all. Just answering someones question about overhead traffic.

Another user here at BBR says that it is even higher when upgraded to Docsis 2. Who knows what Docsis 3 overhead is like. Yeah it's weird - recent Comcast experiences is that when I have a switch plugged in (multiple IP addresses) the modem will flood the network with packets as the switch activity LEDs are flashing...I don't know what is going over the wire as I haven't had the chance to install tcpdump on one of my routers but it seems rather harmless. This also happens at other people's houses too so it's not someone just DDoS me or something. What I do know is that the traffic is probably against my "cap", but comcast hasn't called me yet to complain so I am not overly worried about it.
On another subject -
I would say the main reason why Comcast (and other providers) wont rollout a bandwidth metering tool is because once it gets out there, people will start comparing usage and prove the ISPs are a lying sack of S$!% when it comes to "average" monthly usage. Especially if everyone's average comes out to 100GB/month (no proof it is or isn't...just speculating) when the ISPs are tooting that on average people only use 5GB/month. | |

Fluff it up a bit. State the cap is 250GB, but in actuality is 255. 
Or go ahead and include such overhead traffic on the meter, and subtract it at the end of the month. Be sure to include documentation about it.

»help.comcast.net/content/faq/Fre···sive-Use
quoting from it:
How does monthly data usage threshold change Comcast's policy on excessive use?
Comcast's overall policy on excessive use remains the same ;the only change is that Comcast now provides a monthly data usage threshold starting on October 1, 2008. By providing a specific monthly data usage threshold, Comcast is providing greater clarity to its customers about excessive use.
Why did Comcast choose 250 GB as its data usage threshold?
250GB is far beyond the current median of data usage for a typical residential Internet customer in a month, so this amount of data accommodates any reasonable definition of typical monthly residential usage.
To reach 250 GB in a month, for example, a customer would have to do any of the following:
Send 50 million plain text emails (at 5KB/email)
Download 62,500 songs (at 4 MB/song)
Download 125 standard-definition movies (at 2 GB/movie)
Upload 25,000 hi-resolution digital photos (at 10 MB/photo)
What is normal or typical use?
Data usage changes over time as Comcast's customers use the Internet and the services and applications available for it. Currently, the median data usage by Comcast High-Speed Internet customers is approximately 2 - 4GB each month (these numbers may vary on a monthly basis). This reflects typical residential use of the service for purposes such as sending and receiving e-mail, surfing the Internet, and watching streaming video.

Galt, CA | I was kind of worried about caps until I actually took a look at what im using on an average month. so far this month, im at 29 gigs. thats having a media server and watching streaming video on my tv most of the day, 2 desktops, 2 laptops which at least one of them is running some game or another most of the day, an airrave and game consoles.
it makes me wonder what on earth people could be downloading to account for 1tb of data transfer?
i dont really care that they do it, but... i cant for the life of me figure out what there is to download that would account for that much in any given month? | |

kudos:1 | I still doubt that they intend to release it. If they release a meter, then you will see posts here and on the Comcast forum from people that used 400 GB without any consequences, and from others that got threatened with termination at 280 GB. That's a nightmare Comcast cannot afford.
I suspect that they are rethinking how to set caps, and possibly bill for overages rather than terminating customers. | |

2 edits | Not everyone is interested in using McAfee bloatware, or can even use it in the case of those using Macs or Linux/BSD boxes. Plus you have the little problem of having to total up all bandwidth usage among multiple computers, assuming you are using more than one. That total still wouldn't include data consumption from standalone devices like alarm monitoring equipment, Slingbox streaming content, data accrued by VoIP ATAs or consumed by an Xbox 360 streaming Netflix content, just to name a few common residential applications.
The closest you can get to a panacea in this regard is by using third party firmware with some routers, like Tomato or DD-WRT on a WRT54G or Buffalo router. I personally use Tomato on my WRT54G, but I would still like to see what Comcast says I have used. I would like to have the opportunity of discovering any disparity between Comcast's total and the total logged by my router in the event there was one, but hey, that's just me.

That's all nice but my router can't handle Tomato (WRT54G V5) and I'm not sure if DD-WRT Mirco has a bandwidth meter. (Its another router firmware besides Tomato)
Not to mention I read that flashing my certain router can brick it pretty easily since it sucks so bad. And I don't have the money to go out and buy a new router just so I can monitor my bandwidth because Comcast feels it needs to cap its users and not provide them a meter themselves.

Meter might be trouble for ISP's.
Leave you cable modem and properly secured router connected while you are away. Check you usage regularly while away and find that you are still accumulating usage. I guess the ISP might have some explaining to do. No broadband meter no complaints about the above.
There is the issue of unpredictable traffic generated by the operating system and application patches each month. Imagine being close to your allocation and your operating system downloads patches that put you over your allocation, the day before your account resets. Subscribers should not find out how much a patch will download after the fact.
