Comcast's New Throttling Plan Uses Trigger Conditions, Not Silent Blocking
clang_jangle writes with this excerpt from The Inquirer outlining Comcast's new traffic-throttling scheme, based on information from Comcast's latest FCC filing. "Its network throttling implements a two-tier packet queueing system at the routers, driven by two trigger conditions. Comcast's first traffic throttling trigger is tripped by using more than 70 per cent of your maximum downstream or upstream bandwidth for more than 15 minutes. Its second traffic throttling trigger is tripped when the Cable Modem Termination System you're hooked-up to – along with up to 15,000 other Comcast subscribers – gets congested, and your traffic is somehow identified as being responsible. Tripping either of Comcast's high bandwidth usage rate triggers results in throttling for at least 15 minutes, or until your average bandwidth utilisation rate drops below 50 per cent for 15 minutes."
Comcast's first traffic throttling trigger is tripped by using more than 70 per cent of your maximum downstream or upstream bandwidth for more than 15 minutes.
Eh? In scandinavia countries new laws will state that "the speed of the line must be atleast 75% of the said one during 24 hour measurement period". And you get throttled with comcast if you're actually using more 70% of what you should have? Why do you put up with this shit?
How can they advertise xx mbps when you can only use said speed for 15 minutes? Shouldn't it be advertised as a burst speed with a real speed of 70% of burst speed.
What if you throttle your own connection for 5 seconds every 14 minutes? (No, I don't agree with the policy. At all.)

Security Scan and Virus Detection do not work with your operating system.
Falsely advertising. Isn't that what this really comes down to? It seems like Comcast is allowed to do what they want with the service they provide. But they need to advertise it correctly.
Not sure about the monopoly bits though.
So you've hit the 250GB cap, but you aren't a pirate. You pay for everything you consume - including bandwidth. Your only crime is that you went to another company for video service. You like your Apple TV and the iTunes store, or you like using a slingbox, or you like movies on demand from your Roku, or your DirecTV receiver.
All of these technologies may cause you to run over your cap, and they all have one thing in common - they directly compete with Comcast's video services.
Now Comcast appears to be using their broadband monopoly, in the form of transfer caps, to discourage the use of competing services.
If this isn't the very definition of an abusive monopoly, I don't know what is.

ISP's should be legally obliged to advertise only what they actually offer. If you can only use half, then they can only advertise half with any burst capability added as a possible extra.
This article is from January. Maybe it got throttled somewhere.
If they are going to "throttle" my service, it seems only fair for me to "throttle" my payments.
"Oh, you've been billing 100% of the advertised rate for the last 4 months? I'm going to have to cut you down to 50% until your annual average is under 75%..."
I read the FCC paper.. the summary is full of errors. The individual user does not get throttled until the entire CTMS port is in a congested state (that's 80% downstream, 70% upstream). And 'throttled' is a loose term.. if the bandwidth is available you get it. You are throttled if there are lower volume users on the shared pipe, and even then they just get a higher priority. Depending on how bad the congestion is, you might not even notice this.
Comcast rolled this out nearly a year ago.
And its not throttling, its a fairness mechanism: It means that light users won't get outcompeted by heavy users, but heavy users shouldn't get starved out unless things are really REALLY bad.
Test your net with Netalyzr
During the time that a subscriber's traffic is assigned the lower priority status, such traffic will not be delayed so long as the network segment is not actually congested. If, however, the network segment becomes congested, such traffic could be delayed.
So what they are really doing is lowering your priority. If there is no real congestion then you notice no difference. If things get saturated then your packets are delayed before other peoples.
It sounds reasonable to me. If it doesn't, you may need to accept the fact that you're not at all guaranteed that you can get your full 6Mb download bandwidth 24/7. If you thought you did, sorry; you misunderstood, possibly because of shady (but probably not illegal) advertising, in which case I don't blame you for being angry. But a reliably 6Mb connection is vastly more expensive than the $50/month you're paying, so your anger is akin to being disappointed that the 120 MPH car you bought isn't guaranteed to make your 10 mile commute in 5 minutes during rush hour.
Or you can run at 100% for 14.5 minutes, automatically throttle yourself for 30 seconds, then go back to 100% for another 14.5 minutes. So for a 24 hours day you would be at 100% for 23.2 (non-consecutive) hours. Meh.
I judt got a nre Kinesis keybiartf so please excusr ant egregiou typos.
The 250GB cap mentioned in the article does not affect business customers (I called to confirm it). I know I have a contract for 3 years (they were the only ones who could deliver service in my area), and was so floored by the assertion that all customers would be subject to bandwidth caps, I called about it. The rep informed me that there is no bandwidth cap for business customers, although if you do use a lot of bandwidth, they will let you know about it (I have no idea what limit would trigger that event or anything, but then again, neither did the rep I spoke with).
I got nuthin
comcast can suck it. maybe off topic, but i just ditched them.
* they advertise how customers will need to do nothing for the digital conversion. then we get boxes
* they've lied to my mom about prices, she called up before she had somethign done, they insisted it was free of charge, then she got a bill with.. charges on it, now it's of course it's not free.
* internet sucks, last few months during the evenings i had lag spikes all the time.
i've switched to verizon fios and so far i like it better, plus it's a few bucks cheaper. hoepfully i'll continue to liek it
Simply put, there are four steps to determining whether the traffic associated with a particular cable modem is designated as PBE or BE:
It must have been something you assimilated. . . .
Where in the world did you get that info? And define 'good'. Like VHS quality? Or YoTube video quality? Also, some of use (like those with large families) can easily go through double-digit hours of Netflix streaming daily (especially in the Winter when going outside is not really an option). It's not the 1960's anymore....whole families don't gather to all watch the same show at the same time.

The linked PDF says what is required, though in reading the FCC filing, the summary is a bit incorrect.
Basically Comcast has 2 levels in the tier (called PBE and BE)
Everyone starts out as PBE level.
To get moved from PBE to BE, all of the following have to occur
- That particular network segment needs to be 'nearing congestion' defined as 70% upstream limits or 80% downstream limits for 15 minutes.
- A particular user has to be 'significantly contributing' defined as 70% upstream or downstream limits for 15 minutes.
Being placed in BE means that if there is congestion (meaning priorities have to be determined) any delays will affect BE traffic before PBE traffic.
To be removed from BE status you have to drop below 50% for 15 minutes
I think it is good that these are coming out in the open and being shared, and I think it is a step in the right direction since they state they will no longer use a protocol based management method. If there is congestion on a network, someone has to suffer, and it seems reasonable that those placing the highest load should be the ones to feel the effects first.
I do think, however, they need to mention more explicitly that the speeds they market are theoretical maximum allotments, and to give a average attainable bandwidth if everyone in their (block, building, etc) were to maximize usage.
Your "math" is full of unwarranted assumptions. Chief amongst them the mother's-basement-dwelling single nerd's view-point. Lets try this with a family of 4 using Hulu/Netflix/iTunes/what-not combo to watch TV, movies, sports, buy music, get Anime etc. That's slightly over 2 hours a day per person. Not so "unreasonable" anymore, is it now? And 2 hours a day for kids/teenagers is somewhat a conservative estimation (and am I not master of understatement or what?).
that's YOU. that's not why we as a country don't have it this way.
btw: we already have government standards on what can be legally called broadband. they're quite clear, and completely apolitical (beyond being unreasonably low.. pretty much everthing DSL or cable qualifies)
If you cannot keep politics out of your moderation remove yourself from the Mod Lottery.. NOW!
I only agree 70%.
Your post has been up more than 15 minutes, so you're probably only in agreement 50% now.
Fine with me. As long as you don't do so for more than 15 minutes.
Good video over the net is 2 Mbps for Netflix.
MAYBE that's true for netflix. It isn't true for other services.
I'm looking at season 1 of "Parks and Recreation" from Itunes at 720p.
The bitrate of these episodes is roughly 4.5Mbps and it is just at the bare minimum of what I consider acceptable. They are going to need to more than double that for good quality 1080p, say at least 13Mbps for broadcast-quality (not blu-ray) 1080p. For example, NBC's nationwide 1080i backhaul is 15Mbps h264 and they are the lowest bitrate of all the major networks, ABC is roughly 35Mbps h264 for their 720p backhaul.
So, 13Mbps for decent 1080p material - that works out to:
~4.0GB at good 1080p
~1.5GB at itunes quality 720p
for typical 42 minute show with no commercials.
That puts comcast's cap at about 2 hours a day for good 1080p or 5.5 hours at itunes quality.
For an entire family, with no commercials.
The average television is on for more than 8 hours a day in the US.
That puts comcast's 250GB cap at about half of the necessary level for itunes quality television, and a quarter for good quality 1080p. For the AVERAGE family. It doesn't account for the bell-curve at all. The cap needs to be more like 2TB to cover the average household video consumption out to the 1st standard deviation.
When information is power, privacy is freedom.
Comcast is a monopoly in my area (Twin Cities). How exactly do I vote with my dollar?
You know who else used a similar throttling scheme?
Nazi Germany.
