Re: [Connectivity] Comcast throttling?
said by alfnoid  :little birdies say that it IS so. It is apparently supposed to affect the incoming (to the comcast network) only...for now anyway. Don't know any more details as the birdies I listen to didn't have anymore info than that. I am seeing evidence of this, but it's not conclusive.
CacheLogic ( »www.cachelogic.com/ ) shows up in my firewall log from time to time. Most recently, they showed up while I was downloading a popular linux distribution -- a legal file -- via BitTorrent. I went to their website and, yes, that's what they do. They identify file sharing traffic for ISPs.
My speed did not seem affected at all. It was a fast swarm. Perhaps it's just monitoring for now. Or perhaps they ignored me because they got dropped at my firewall.

lol, i remember when Rogers first throttling our bit torrent, the dslreports forums was filled with 100's post. Im sure if Comcast did throttle p2p, lots of people would be posting in numerous threads.
As for comcast admitting they throttle, they probably wouldnt at first. Rogers reps denied it for months until enough people called in, it force them to give their agents a pretyped comment to read  |

said by Dark Shikari :When uploaders try to connect to a client, it instantly issues a 10053 error, disconnecting them. 10053 is WSACONNABORT which means that the local side (your OS, network software, or device driver) closed the connection on purpose.
Typically:
- software firewall
- no remaining available buffers or ports
- protocol timeouts
Let's rule out the last one, since you said this happens instantly. But it is that last one where Comcast could be implicated. By filtering ACKs and FINs coming back to you, they could create the error number that you're giving -- but it wouldn't be instant -- it would several seconds to several minutes.
I'm wondering what has changed over the past couple of weeks that could be affecting you. I'm on Comcast in Hillsboro and I'm uploading on ED2K and seeding on BitTorrent without issues. I'm using Shareaza which does not support encryption on BitTorrent, yet.
P2P users like to use that hacked TCPIP.SYS file. I don't. Do you? Perhaps one of the recent MS security patches is conflicting with the hacked TCPIP.SYS.
I don't put much weight into those forum reports and the Wiki that you linked. They put Comcast on the list rather quickly, with very little actual evidence. And, like I said before, that error message doesn't really jive with traffic shaping.
I may end up with egg on my face, but try this:
Open a tcp connection (either telnet, ssh, ftp). After it is established, disconnect your network cable on the WAN side of your router. The error message (or other behavior) that you get is the one that Comcast could generate.

gotta say there gd16... that is pretty arrogant to say you know everything because you have a degree.
pretty stupid too.
you may be right as it seems likely that someone with inside knowledge is confirming this to be true, but don't be an jerk with your degree shoved up your ass.
I can tell you of many times where people with masters degrees and even doctorates have told me what is wrong only to prove them wrong once they let me do my job and stop telling me what my job is.
moral of the story is be somewhat open minded to the possibility that you could be wrong...because it IS possible, humans do make mistakes. |

Yes, I am analyzing your data. And I am not seeing the same symptoms that Rogers Cable users report, where ISP throttling has been verified.

If they're knowingly throttling upstream, or P2P traffic in general, they sure as heck aren't doing it in my area. I've had my LAMP server seeding torrents day and night for a long time ago, at 20 kilobytes/sec, and haven't been capped, yet.
While it's suspicious, I suspect something else is at play.
Before we jump to conclusions, people should be very specific about what their conditions are, if they're suffering from this alleged "throttling".
If you're currently seeing the behavior characterized in the previous posts, please post:
•What BT client you're using, and the version
•What port you have the service bound to
•Whether you're using encryption (specify forced or not)
•If you can see other seeds/peers, and which ones work
•If you are using NAT, and what model
-and-
•Briefly describe the behavior, whether you cannot seed, whether it cuts in and out, e.t.c.
This information should give us a better picture of what's at play here, and whether Comcast has stooped so low as to throttle BT/P2P traffic, as some other ISPs have done.

said by gd16 :...obviously you think I have an extremely low intelligence level. Can't be any lower than mine. 
However, I still have to wonder. What is the point of killing the completed download? The worst impact of upload is saturating the bandwidth, and that is happening during the download, as well as after.
Unless, maybe it isn't bandwidth they are trying to limit, but upload volume? They are willing to let you download, but they don't want you going over a TerraByte of uploaded data? Something like that.
IOW, I can see them capping down/up performance; other cablecos do that routinely. I don't understand letting the torrent run unimpeded until it is complete, then killing it altogether.

I see what you are saying in this post...obviously you think I have an extremely low intelligence level.
My peers drop to zero the second I complete. And while the tracker shows 50-60 leechers.... my client sees none. They appear for a brief second until comcast's software sends the disconnect.
I understand how trackers and bittorents work. I am telling you Comcast is doing this now. Perhaps not to you or your service error. But this is really happening to me. |

said by gd16 :and bit torrent works just fine when i am downloading AND uploading. However, when I complete and am only seeding. The connections drop right off to zero. Variable nature of the tracker. In the last week I was downloading episodes of an anime show. On a couple of episodes I got very good D/L speeds, on the order of 224KBytes/sec (3008/512 DSL). On others I got lousy downloads. On some episodes there were only a handful of seeders, leechers, or both. At least one episode saw my upload drop to zero after I completed the file, but while I was still in seed mode. When I checked, there were no leechers at all in the torrent.
I once had a show that took five days to download! Very low activity, and I hit 98% complete when the number of seeders went dry.
When I was connected to that Comcast connection, I never saw max download on any anime torrents; I got the max download pulling a Knoppix LiveCD ISO image.
Indeed, after upgrading to AT&T Yahoo! HSI Pro (3008/512), I have yet to max my D/L. If it is "throttling", though, they aren't doing very well. Hard to think that there is throttling when I can get 224KBytes/sec on a good torrent. I suspect that there just aren't enough well populated seeds for the niche genre shows I am fetching.

this just started happening to me in Portland a few days ago. When I kick BitTornado into super-seeder mode I can maintain connections. The work around is to use encryption via Azareus or uTorrent. But that doesnt help if the people you are connecting to are not running encryption. |

It would have to be within the last month, or two. I was downloading with BitTornado on a Comcast connection, and got full download speed. In June.

I use mainly bittorrent also, but there are good uses for eMule. It seems to be the best network for getting very rare files that one can't possibly find on bittorrent or newsgroups. For example, there are all sorts of remixes of songs that would probably take ages to find using google that are right there with emule. |

I personally don't care about emule/edonkey or that crap, but I do use bit torrent some and would be pissed about that.
