    comcast throttling giganews

    comcast is throttling my giganews server. does anyone have any ideas
    if this is permanent, applies only to nntp packets, or how comcast
    does this.

    Haven't had any "throttling" problems downloading either an 81 meg file from
    lucasarts or the 4.3 gig linux dvd; did the download via a command mode
    ftp client.

    Do have sporadic disconnects of about 1 sec while listening to web audio
    streams.

    Just remembered regarding the download of the linux dvd is that it dies of
    disconnects when using the browser to get the iso file; switch to command mode
    & got the 4.3 gig at about what is a bit higher than 6 mbps.

    IF they really are throttling it is done at the main station and there
    is nothing you or I can do about it. Are you sure they are throttling?
    Could it be just a slow net and/or a slow connect point? Look here and
    then click on the closet to you and you can drill down to see if yours
    is slow. http://www.internettrafficreport.com/main.htm

    no absolutely sure about it. i have 16MBit, and up until about a month
    ago, i coudl pull in about 2.2megabytes per. then for about a month i
    was downloading some huge files. then one sad day i connected my
    newsreader and i could never, ever get past about 1 MB per down, most
    of the time dropping into the high K's. it looks like these jackasses
    start throttling you and never unthrottle you. i swear that those
    people at comcast are lost in space. as with everyone else in the
    universe, once FIOS comes to town they hoover all of comcraps internet
    customers. I just do not have FIOS yet.

    Can you D/L other files from other sites at higher speeds ? It could
    be the news server itself is the problem.

    Did you check your modem to see what it's throttled at ? It might not
    be giving you the 16Mb that it should.

    When I had Comcast cable, the giganews server was throttled.

    Now that I am on FIOS, news server not throttled. News server
    connection was overloaded.

    Solution: server only carries Big 8, text only, news group.

    may or may not be related: Comcast discontinued their 2Gig/month
    usenet service (through giganews) about a month ago. I mention it as
    the time frame is similar. If you were not using that......nevermind.

    no i tested it with stunnel, and tested d/l speed on dsl reports.
    accrding to reports I am getting 16MB, (at least close to ny). it's
    the not the modem either. I think i read a report on dsl reports that
    comcrap's throttling is now 100% everywhere. Maybe if you upgrade to
    ultra (22MB), comcast will throttle you down to 300 baud.

    You read it wrong. I don't even know where to start. I guess maybe go
    back and read it again.

    I have Comcast, have for many years now, and have never experienced
    throttling. I up and sownload several cd's worth of data every month
    and have no problems. I can almost always get the 6mb and the boost up
    to 12, or 16 or whatever, from most sites over a large downlaod. Now
    there are some sites I can not get over 2 or 3mb! But that is the same
    on my friends FIOS too. I used to use giganews, comcasts news server,
    I have been thru several. I now use EasyNews for all my newsgroup
    stuff, yes it is a pay for use service, but I can up and download with
    no throttling at all. I use EasyNews because of the retention and the
    small amount I have to pay to get it. EasyNews does limit its
    uploading to 200 posts in a 24 hour period, but that is not a problem
    for me.

    I'LL TRY AGAIN. can i download from what other sites? http? nntp?
    torrent? Binaries? what are you talking about? since all newsfarms are
    generally subscription, i can obviously only test one or two, because
    i have to pay for them. On the web, it depends on who you are
    connecting to, to what the bandwidth is. You ask an impossible
    question. I do know it was halved or more, from the same nntp server
    farm. How can I check comcasts modem, to see what it is throttled at?
    I am unaware of this procedure. Unless it is software diagnostic on an
    rca cable modem, I might be out of luck, as i don't want to buy their
    modem.

    it depends on how much you download per month, or at least it did.
    if all you downloaded in a month was several cd's, let's say about 3
    gigabytes per month, with a 250gigabyte cap, comcast wouldn't throttle
    you because your d/l is really small. i have been downloading from
    giga,newscene,apn and a few more i forgot for about 10 years now and
    of course up until comcast sent out their throtte email last month, i
    was never throttled at all and use to pull down binaries at about 2.2
    Mb.
    you get throttled when comcast looks in your direction and thinks your
    downlaoding has become too large for their taste, although dsl reports
    said that comcast now has a full time throttling algorithm in place,
    but I don't know how accurate the report is. It seems that comcast
    used to keep you throttled, if they had ever throttled you. I am using
    'you' metaphorically. please, just because you have not experienced
    something does not mean it doesn't exist, it jus means that you have
    not experienced it.

    Any site that has something you're interested in.

    >http? nntp?


    Yes and yes.

    >torrent? Binaries?


    Yes and yes.

    >what are you talking about?


    Huh?

    >since all newsfarms are generally subscription, i can obviously only
    >test one or two, because i have to pay for them.


    Generally true, but most of the majors have free trials, some lasting
    as long as 10 days, IIRC, so if you don't mind burning a free trial
    opportunity you might consider that. In addition, some of the pay
    servers have plans starting at less than $5 a month, so that could be
    another approach if you need a longer term test.

    >On the web, it depends on who you are connecting to, to what the
    >bandwidth is.


    True, but you can almost always greatly improve the situation by using
    a download manager that opens multiple concurrent connections. I use
    and recommend FreeDownloadManager (www.freedownloadmanager.org) for
    web downloads, and a multithreaded news client like Newsleecher or
    Newsbin Pro for Usenet. It's rare these days to encounter a mainstream
    website that doesn't allow you to open multiple concurrent
    connections, and again, concurrent connections are the key to greater
    download speed, whether it be from the web or Usenet.

    >You ask an impossible question.


    I didn't ask any questions in my previous reply.

    >I do know it was halved or more, from the same nntp server
    >farm.


    Nothing was halved that I'm aware of. Can you be more specific?

    Chances are excellent that your modem is throttled to the speed tier
    that you're paying for, so that's a good first step. Beyond that, use
    the "multiple concurrent connection" approach outlined above and you
    should have no trouble filling your download (or upload) pipe. Stay
    away from so-called speed test sites, as they don't move enough data
    to provide meaningful results.

    Try posting the brand and model number and someone will tell you if
    status pages with that info are available from the modem.

    My Terayon TJ715X has status pages at http://192.168.100.1 - some have
    passwords and others don't.

    I don't think there have been any credible reports of throttling on
    Comcast in recent years unless you want to count the forged RST packet
    issue from last year, but IMO that was too crude to be called
    throttling. Prior to the soft 250 GB cap that was recently announced,
    the even softer cap was somewhere between 400-800 GB, so by an ISP
    yardstick it was pretty generous. Even so, if a person's activity rose
    to the level of getting noticed, they still didn't get throttled.
    Instead, they would get directly notified and asked to tone it down.

    >you get throttled when comcast looks in your direction and thinks your

    Not true. The system throttles a user's connection if a particular
    CMTS port is congested, and if that user has been identified as a
    primary reason why. The system will flip a user from the standard
    "Priority Best-Effort" traffic (PBE) to lower quality of service (QoS)
    "Best-Effort" traffic (BE) for fifteen minutes if they're a major
    reason congestion exists.

    That was never true, and also isn't true now under the new system.

    yes, i have tried. it is random speeds from the web, i have tried 3
    news servers and the one i have been using the longest is throttled
    the most. i have done tests with their support techs and they said it
    was comcast as there was no throttling on newserver part.

    i have done that with 3 news servers, all of them get throttled down
    after several files are d/l. i have emailed tech sipport at all 3, and
    all of them said it was comcast.

    you obviously do work for comcast, i suggest that you actually go to

    I know, 'dls reports' is lying.
    since you have indicated you work for comcast, further discussion is

    What's this about working for Comcast? I'm just someone trying to help
    clear your considerable confusion.

    Feel free to provide a link to where you found a credible report
    supporting your claim that "It seems that comcast used to keep you
    throttled, if they had ever throttled you". You won't be able to.

    Up to 10? So how many was it actually using? Agent isn't known for its

    If you can figure out the make and model of your modem, you'll be able
    to search and see if it has a web server with status pages. Many do,
    and they are frequently located at http://192.168.100.1 although some
    apparently need a login/password.

    Comcast Internet throttling is up and running
    Cunning plan replaces P2P blocking
    By Egan Orion
    Tuesday, 6 January 2009, 11:08

    COMCAST, the second-largest US cable television and Internet
    communications service provider, has a new broadband traffic
    throttling scheme installed and operating in all of its markets.

    The ISP's new regime for restricting its customers' bandwidth
    utilisation replaces its former stealthy practice of arbitrarily
    blocking subscribers' peer-to-peer (P2P) upload traffic, which was
    criticised by the FCC last year after it was exposed by the Associated
    Press and others.

    Comcast's filing with FCC (PDF) says it has put in new hardware and
    software technology at its Regional Network Routers locations to
    effect this cunning traffic management plan.

    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.

    The Comcast two-tier traffic throttling system enforces different
    quality-of-service levels. Internet packets to and from a specific
    subscriber are assigned 'Priority Best Effort' (PBE) queueing by
    default, and the traffic rate is throttled by switching packets to
    lower priority 'Best Effort' (BE) queueing.

    Comcast uses a bus analogy to explain how its two-tier traffic
    throttling system works:

    "If there is no congestion, packets from a user in a BE state should
    have little trouble getting on the bus when they arrive at the bus
    stop. If, on the other hand, there is congestion in a particular
    instance, the bus may become filled by packets in a PBE state before
    any BE packets can get on. In that situation, the BE packets would
    have to wait for the next bus that is not filled by PBE packets."

    According to the company, upstream and downstream traffic is managed
    separately, and its router packet queueing increments - the waiting
    time between each 'bus' in its analogy - are two milliseconds, or
    1/500th of a second.

    Comcast says that a throttled subscriber's connection that is forced
    into the lower BE quality of service queue "may or may not result in
    the user's traffic being delayed or, in extreme cases, dropped before
    PBE traffic is dropped."

    Thus, Comcast's latest traffic throttling method can lead to transfers
    being blocked, too. But only in 'extreme cases' it says, so that's
    alright then.

    Comcast has also imposed a monthly 250GB bandwidth usage cap on all of
    its customers, and it will, after one warning, terminate service for
    one year to those who exceed that cap twice within a six-month period.

    So you punters who signed up with Comcast as your ISP can be assured
    that the company will deliver only about half of the maximum bandwidth
    it advertises, on a consistent basis.
