Comcast defends BitTorrent blocking in response to FCC

13 February 2008 23:22 by Rich "vurbal" Fiscus | 18 comments

Comcast defends BitTorrent blocking in response to FCC In a 80 page filing with the FCC, Comcast attempted to explain why there's nothing wrong with the "network management" practices that spurred a number of complaints to agency regulators. The problem is they're not really offering new facts. While they're finally admitting what was proven several months ago - that they've been tampering with P2P uploads from subscriber computers - rather than offering an explanation that puts the practice in a new legal light the company's official position is still just that they haven't done anything wrong.

"The carefully Limited measures that Comcast takes to manage traffic on its broadband network -- including its very limited management of certain P2P protocols -- are a reasonable part of Comcast's strategy to ensure a high-quality, reliable Internet experience for all Comcast High-Speed Internet customers," read the company's statement. It added that the BitTorrent file-sharing protocol "utilize(s) immense amounts of Bandwidth in ways that are unpredictable and inconsistent and that can threaten to overwhelm network capacity and harm the online experience of other users."

The company's comments include some specifics on how BitTorrent traffic is handled. It explains that during certain peak hours they disrupt traffic from subscribers who are uploading using P2P applications, but not downloading at the same time. It also states that neither downloads, nor uploads taking place simultaneously with downloades, are affected.

The big problem with Comcast's claims is that they don't seem to match up with reality. For example, according to the company sending reset packets that claim to come from remote P2P clients is completely legitimate becuase of the potential for this traffic to affect other users. If, in fact, company executives believe that claim it begs the question of why they refused to even admit the practice until the issue was forced by the government.

    How about boosting the overall bandwidth for USA users since, ya know, the United States has the slowest rating in the world. Instead Comcast wants to cap the already paltry bandwidth already available.

    Comcast can't do a thing to cap bandwidth. That is so backwards when you think about advancements in technology. Someone will go faster, and soon Comcast will be left in the dust. Keep up or get out.

    Comcast are selling a service that they are not providing and their interference is having the effect of blocking connections being established sue their asses. This happens in the UK and the isp's over here use the same lame lies as comcast, both Tiscali and Eclipse Internet use the same method of throttling that comcast has employed to save them money and block connections being made via p2p, by creating tracker errors, forced disconnections & spoofing packets. All get your MAC code and leave anti consumer as there are many good isp's out there.

    Tiscali & Eclipse Internet are possibly the worst two isp's in existence & now Pipex since Tiscali purchased them.


    Bad ISPs
    http://www.azureuswiki.com/index.php/Bad_ISPs



    The BPI Are: SONY, UNIVERSAL, WARNER GROUP, EMI.

    The RIAA Soundexchange Are: SONY, UNIVERSAL, WARNER GROUP, EMI.

    The IFPI Are: The same anti consumer lot as listed above!

    The MPAA Are: SONY, UNIVERSAL, WARNER GROUP, DISNEY, PARAMOUNT, FOX.

    How do you stop anti consumer = its easy purchase only second hand media and avoid their propertarian hobbled by DRM hardware! http://www.boycott-riaa.com/

    It's called overtrading.. selling something you don't have.. Look it up, it's illegal!



    Free open source software = made by end users who want an application to work.... Commercial "pay for" software = made by software developers who want paying... see where I'm going with this?

    I have Comcast because it is the only hgh speed available here. Let me tell you, from top to bottom, the company is trash. Form their customer service to their service itself, they are garbage.

    My friend and his family switched from Comcast to a DSL provider when they received a letter in the mail telling them that they have been abusing their bandwidth. And from what he's told me, the customer service is extremely poor anyway, so he didn't feel bad about ditching them.

    Comcast, like many ISP's, oversell their service.
    Ex:

    Say a Comcast node can support 250 users. Comcast may put up to 500 users on it, using the logic (albeit flawed) that all 500 won't be online at the same time. The times where you can see the flaw in action is when people get off of work and the loop/node become overwhelmed with users, usually only for a brief period of time (say 4pm to 7pm).

    I believe comcast and verizon already had a tiff over who was faster that was settled somehow (court? arbitration?). And I think thats why you no longer see the turtle ads and others saying comcast is faster, because they are not.

    I might be wrong on the numbers but you will get the gist.. Cable is run over copper wire and has a maximum bandwidth capacity, say 300MBs. When DSL gets completely tweaked they can do 10x+ that speed with no notice of lag/slow down to the end user, because of fibers bandwidth capacity.

    Comcasts infrastructure is also a weak point for them, it is aging. The is alot of signal loss through out their system. Although you will notice that wealthier neighborhoods are upgraded with new copper, better nodes, and usually serviced by actuall Comcast Techs, as opposed to subcontractors. Wire in the "other" neighborhoods is ancient, signal leakage like a mofo. Their HD bandwidth is a mess, doing an install for HD (at least the ones I did) would end probably 40% the time with homeowner rejecting the install (after I was 99% done) because the picture looked like shit, would pixelate, freeze.
    You end up trying to track down why you only have +5dbmv @ the tap, and by the time you get into the house and the box, you are @ -7dbmv.. mostly because the tap has broken connectors on it, squirrels eat the lines and they don't repair sh!t. They will send a sub to patch a damaged trunk line and have em do it with RG11 between two taps, and not come out truley fix the problem for months.


    Moral - Comcast is up to some shady shit. And in the end will be relegated to anus of history just like dial-up. Its why they smash / sue, and pull every other underhanded trick to stop cities from offering free wireless internet to its inhabitants. My guess is they will eventually roll out some sort of wifi, and overcharge for it.. and oversell it as well.

    I had Comcast for less than thirty days. How they've managed to wring the market is beyond my feeble comprehension.

    "Network Management."

    B.S.

    Take care of your customers instead of tampering.

    yes I have been very disappointed since comcast took over for adelphia all they did is charge me more and give me less service.
    they promised 2 meg up and droped me from one meg up to 768kb up
    but they raised the price some 20 dollars more a month...
    its called less for more, and i have had it also with them..
    maybe it is time to go dsl I wish I could get verizon ficos
    well lets see what happens...............WrecK

    The problem is that Comcast is too big of a company. They have bought out 85 - 90 % of the competition so they can rise prices and cut services with out losing the bulk of their customers. I had them for 9 years and i had some of the worst experiences with them. They royally. Again if your the only big boy on the block people will suck it up when they dont have no other options. If Verizon stop being fools and put in more area's that Comcast is in then you would see a change from Comcast. They need serious competition that wont sell out.

    the only problem with that is verizon uses bellsouth lines
    and like verizon told me if your in a bellsouth area forget about it
    so you know comcast is kicking back some thing to bell south!

    They just put in verizon bios in our nighborhood, I have been with comcast for years cause its all we had, my nieghbor just got verizon with its HD, I dont have HD yet but my other neighbor has comcast HD, I checked out both, of course both have same lcd tv's so saying one set might be better than the other doesnt play here, I didnt see any difference, but in a way I hope verizon kicks comcasts ass, they have been kicking ours for years with bad service, over pricing, etc.

    Comcast sucks! However, you may not know you can reduce your fee if you can play hard ball with them. That means you must cancle your service several times. I started with them on the 6 month at 19.99/month. I cancled after 6 months. After 3 months of being cancled they offered me 12 month @19.99. After the 12 months I called to cancle and they offered me 12 more month at $30. I took it. I am probably on the list that will not pay full price. In my area the cheapest BB is $28/month of a slower DSL. That would require an new modem. For $2/month I get double the speed as long as I don't down load P2P.

    I am sure they will not get into trouble for throttling P2P traffic. Anyone using P2P must realse they are bending over for a big kick or worse and no one will come to your aid. Remember, the Media Mafia claims you are a threat to the Ameriac dream. I am sure all our elected officials have received donations for their campains from the slime. I bet you could get an exception for the throttling process if you could prove you were legal.

    For those that are having problems with Comcast do u not have Plusnet there as that is what I use and it's really good. I've had it for 3years and when I moved house I had no problems and am still with them. I would recommend them to anyone. I live in the uk. In Scotland which is a difficult place to get signals at the best of times but I do not have any problems.I don't know if you can get it in the USA but if you can then give it a try.

    empulse is not very smart...

    cable is only ran over coaxial cable from the poll to your house.. the rest of the node is fiber optic lines as well..

    and dsl has much less potential then docsis (cable).

    soon you will see very fast internet from cable, since docsis 2.0 is going to be used widely with channel bonding along with docsis 3.0. with 8 channels and docsis 3.0 (data over cable), the new downstream limit will go from 38mbit (docsis 1.0/2.0) to 304mbit+ (docsis 3.0) with upstreams of also 108mbit+

    Comcast is by means not a slow ISP, they have configs that can reach speeds up to 38mbit right now. These of course are not residential speeds, and nodes have far more then 250 users, most of your larger city areas, have 1,000+ on a node.

    Sign up for forums at www.cablehack.net and learn more about your isp.

    I have Comcast, I have seen sustained 800kb/sec down loads on a good day. That is fast in my book. If you want good performance you need to buy your own modem. The ones you rent are not nearly as fast.

    Thanks for the tip Tom!
