Vuze Study Exposes P2P Throttling By Canadian ISP Cogeco
urbanriot writes "Despite a growing number of complaints on the popular North American consumer broadband site BroadbandReports, employees working for the Canadian cable internet provider Cogeco have publicly denied interfering with torrents on their network. However, a recent plugin put out by the Vuze team exposed Cogeco of being the second worst ISP globally, of those tested. So far, Cogeco has failed to respond to these findings, but recent coverage from the mainstream media and Michael Geist may prompt them to finally admit to their controversial practices."
The report by the Vuze team has some interesting information about other ISPs from around the world as well. Prior to this, Bell Canada was taking most of the flak in Canada for traffic management.
no monopolys or duopoloys - real competition.

How we know is more important than what we know.
I wonder what will businessmen of the future think when they read about how full encryption came to be, taking into account it's speed and complexity problems.
For those who are bored to RTFA and dig through its links, there is a handy Bad ISPs list maintained by the Azureus team.
That being said, there are many ISPs who also do p2p traffic caching, which is not inherently a bad thing. Certain block lists consider those wrongfully malicious as well.
Just in case they get dotted: http://spunts.com/vuze-plug-in-results.pdf.torrent
I use Cogeco cable internet and I haven't noticed this. A well seeded torrent will max out all the bandwidth I pay for (16 mbit). I use their pro service now but the same was true when I was using regular highseed only capped at 10mbit They just enforce a soft bitcap which is annoying but I'm only able to hit the caps they are now enforcing because they've made the network so fast.

The CBC has a decent article where they contacted Cogeco. They claim not to use false resets. They also say that they haven't received the letter from Vuze yet.
http://www.cbc.ca/technology/story/2008/04/22/tech-vuze.html
I'm not sure if I believe them or not. When I lived in Ottawa last year I had friends using Cogeco. Some people had no problems at all with bittorrent while others couldn't use it. It's hard for me to tell if they are blocking some of their customers, or if my friends just couldn't figure out how to set it up.
It seems to me that when an ISP states they do not throttle traffic and secretly do so anyway, they are giving their customers a false representation of the product they sell. Probably their EULA gives them the right to throttle traffic, but does it give them the right to lie about it?

... when it's transparent and disclosed. If ISPs believe that traffic shaping is a legitimate cost management solution that most customers wouldn't mind, then fine, make the legitimate case: use traffic shaping and disclose the existence of traffic shaping in your plans the same way maximum bandwidth is disclosed, and we'll let the market decide. Personally, I believe that enough customers wouldn't mind traffic shaping, bandwidth throttling and caps, etc. that in the future we might see different priced "tiers" of internet service, which is fine with me as that would make service pricing more representative of internet use. My ISP wants to bandwidth cap my internet service? Fine, if they disclose these caps at the time that I sign up. Then I'd be free to negotiate with another provider or sign up for a better plan. It's the fact that ISPs today advertise one thing and then deliver another that's truly offensive.
The sneaky underhanded meddling with the service of customers that have existing contracts just undermines the ISPs' case and suggests to regulators and customers that they aren't interested in honestly selling a service.

... when they read the networks with the worst median reset rates from the appendix of the report?
UIUC - University of Illinois - 90.69%
WN-AZ-AS - Arizona Tri University Network - 89.33%
I'm not saying there is anything nefarious going on there. These networks were only sampled for a short time by a small set of users. The results gathered might not be generally representative of those networks. But it does make you wonder. Are they are blocking / shaping traffic, or do they have a massively overwhelmed network? Other?
I prefer rogues to imbeciles because they sometimes take a rest.
"Tired of the internet pig next door downloading illegal movies next door and bringing YOUR service to a crawl?

We don't feed the internet pigs!
Sign up with us and get your work done!
(in mice type) we throttle P2P, bitorrent, etc...."
See, no probelm.
This "study" is a joke.
Resets happen under a variety of conditions.
Without analyzing a packet capture to determine the source of the reset this is utterly meaningless.
Even more so since this is a self selected population of users, the majority of which, likely think their torrent is broken.
The sample size is miniscule! A whole 22 users!
Networks that are known to not perform any of this bogus reset bullshit still accrue in excess of 10%. Big deal.
Such a bunch of kool-aid drinking morons.
We at LBE are proud to introduce our new pricing policies. They are as follows: 6 Mbit/sec down - 512 kbit up -> $15/mo. 1.5 Mbit/sec down - 128 kbit up - no RST -> $45/mo. Remember, LBE (Lousy Broadband Experience) are here to satisfy all of your emergent broadband needs. Thank you for using our services.
And have not noticed any throttling. My P2P programs work fine if they were able to work any faster I would be shocked. I do not believe Cogeco is throttling.
There's a rumor they still have some Internet there...
sure. stop traffic shaping and let all those
who use the internet for normal, legitimate usage
get completely screwed by thoth who use it to download the latest illegal xvids of movies.
yeah. great. f**k all you P2P users

Confucius say, "Find worm in apple - bad. Find half a worm - worse."
And having a mix of the two makes it even easier to hide behind plausible deniability. Because placing the right person at the right place, i.e. the worst net admin on the most loaded network might be just what it takes.

Do our, and it seems the Canadian Government officials understand how important net neutrality is? How would they react if some private companies decided to throttle traffic on their countries roads unless they were paid? It is the very same thing.
To bad I am not a big corporation that can say, I think that blue trucks can only go 40 MPH (64.37376 kph, for the Kanucks) unless they pay me. Even though they are on a public right of way.
Yes this is silly, but so is allowing internet traffic throttling.
This is simply greed run rampant, and total disrespect for the law by those companies that think they can get away with it.
So There.

Measuring RST is an interesting approach, but is hardly the only or even preferred solution to TCP/IP congestion control. Delaying [queuing] ACK packets is more transparent and should trigger source reductions.
You have got to be kidding. A self selecting sample of 22 individuals and this is proof?
Is it not just as likely that these 22 people have lousy connections, and so installed the plugin to 'prove' its their ISPs fault? Meanwhile, thousands of others have no problems, so have no need or desire to install the plugin.
Shaw interferes with SIP so they can flog their own 'digital phone.' When is that excrement going to hit the fan...?

I'm perfectly happy with my Cogeco service. I transfer ISOs all the time and get transfer rate in the 5Mbit range. I rarely resort to torrent -- it is unnecessary -- but it seems to work well enough as well. And if there's bandwidth contention, I would want it to be the torrents and not the direct transfers that were hit. That's the point of background.
One the other hand, I have experienced many service providers -- most recently and the Fairmont Banff Springs Hotel -- whose service is crippled.
This study compares the number of RESETs to the total number of connections made. It makes NO ATTEMPT at determining if the resets are false and injected by the ISP.
Egg on your faces yet assholes!!?!? You didn't think anyone would notice the throttling eh? I thought at first my router just sucked and couldn't forward ports correctly, or I had a faulty modem, or some other dumb shit - instead it's been you all along. I hate being in denial that the company I had trusted and spoke so confidently for has been resorting to these underhanded tactics for so long. And then, after making an anonymous posting on Broadbandreports.com that they didn't like, they somehow weaseled the IP address I posted from out of the site admins.
You might have fired me, but it looks like your customers will have fired you.
Sweet sweet karma baby.
In the UK contention ratios on domestic cable/dsl is 1:50. So bandwidth is allocated on certain assumed behaviour patterns.
P2P messes up that usage pattern by using constant bandwidth for hours/days at a time.
As a company I think I am very happy to throttle P2P traffic if it allows the other 49 households to get a 'quality' experience.
The real issue is with shaping. Virgin Media in the UK have declared that unless the bigger internet companies (e.g. youtube pay them money), their data streams will be shaped to reduce load on Virgin's network. http://tech.slashdot.org/article.pl?sid=08/04/13/1913241
Throttling P2P traffic because little Timmy 4 doors down wants to share pirated music etc is fine by me. If he has an issue, go ask daddy to switch providers. Get the hell away from downgrading my cluster.
About a decade ago I was with them, and I always had problems. Imagine playing Starcraft and getting disconnected for no damn reason. I wrote to Blizzard with the error information, they told me to call my ISP. I called Cogeco, they said that my computer wasn't configured properly.
But if I took my computer and went to a friend's house to play, everything worked fine!
Cogeco just plain sucks, and this is just another nail in the coffin for them.
I had "10mbit" service on Cogeco in windsor, ontario...
...
It was my third and fastest Cogeco line at different locations.
Network Node saturation was unbelievable - in those days Limewire and a couple of other sketchy apps were the de rigeur and most people, particularily in the sketchy university and college areas (its like drunken party central there) - the p2p direct connect apps were typical set to 0 0 (full speed) everywhere and as a result anything from loading web pages to IMAP just plain didn't work.
The segment the 10mbit line was on was less saturated in comparison.
This was 2003/2004 - I could run an FTP to certain sites and get a nice even 10mbits.
However, Torrent or especially emule was OBVIOUSLY being messed with. On DSL with Bell or anyone else I was used to get ting a good solid 200-300KB/s sustained, and I definitely knew how to tweak my client for max performance.
On Coegeco I was never able to get more than 50-100KB/s and connections would drop constantly. Telnetting to the ports on remote clients would just disappear into thin air. Average upload speeds were under 1KB/s vs. a normal 4-5KB/s or more.
This didn't make sense, I was able to get far higher connection rates on 1mbit DSL lines and what really boggles my mind is that I actually get better sustained rates right now on rural radio packet infrastructure which is capped at 80KB/10KB. Thats totally non-sensical. The line i'm on now, with a small rural former telco (government protected at that, despite that they can't provide service even close to what the government requires for that protection - they just lobbied out the competition with exclusive zone rights and then said "oh, we'll upgrade the equipment in the next 10 years...)
Anyways, Cogeco was expensive and it really stunk, at least in Windsor.
I've been on 6 different cable providers, and all of them sent me HUGE over-use bills (Videotron in montreal once sent me a bill for over $500 in 1999, for using I think 5gb of download) but cogeco by far takes the cake.
Normally now I use a DSL provider that uses some of the bell network, so far I haven't run into obvious problems with download speeds, latency, etc.
I do really wish P2P applications would start more aggressively routing on local WAN's over distant links and do a better persistent costing analysis over different routes.
Then again, all that the major move to Torrent has done is created limited content, hollywood-like homogenization of content on the network. Foreign content I used to find easily on Emule is now on foreign language sites and difficult to get sources on. Rare music is just plain gone unless your on a private site, and even then each tracker seems to cater to very specific tastes. Old stuff? Good luck. Then I go to the DVD store and notice all the rare/fringe stuff is gone.
I guess both of these factors - the changing ISP climate and the homogonization of media - are turning us into more alike, fall into step consumers. I've even started reading people magazine. Fluff about celebrities really fills the time between boring news stories.
--- ask me about nihilism, I will have nothing to tell you.
I just wonder if some of those RSTs might not be coming from bandwidth hogs -- users who disrupt other users service to capture more bandwidth for themselves. cable is shared medium.
Didn't Slashdot used to have warnings after pdf links? Whatever happened to that?
interfering with torrents on their network
tcp torrent traffic and spam bot traffic are virtually identical. vuze doesn't seem to know this because they look at tcp traffic and p2p lives on both tcp and udp. looking for packets with the rst bit set would better indicate blocked botnet traffic.
It has to be noted that the data gathering techniques Vuze uses are far from optimal. The plugin detects all TCP resets on a connection and doesn't make a distinction between BitTorrent and other traffic, and there is no control group.
if all they are doing is looking for rst flags then they have no real data. the only way to distinguish the traffic is p2p is by looking in the body of the packet for client information. if anyone here has sniffed traffic they know only the most popular p2p clients identify themselves.
Having to work for a living is the root of all evil.
Can we get even? I'd love to see a plug-in for my torrent client that can send a single packet complaint to the DNS servers of anyone who has recently ticked me off every time I start d/lin or u/ling a new block on a torrent. Andy
I don't know about p2p throttling, but I have been a Cogeco customer for years.
Its primary selling point for me is that it is better than Bell.
The short version of my story goes like this. I bought a new computer almost a year ago. At one point I decided to download a whole bunch of old TV shows. I went to log on one day and could not. On my second or third try I then was redirected to a URL that basically said "Cogeco disconnected you". So I call up and basically say "WTF?". The answer I got, is that you have a 60GB cap, that you exceeded. My response was "WTF is a cap?". Their response, it is a cap or limit on how much you can download and upload combined. My response "Since when?! I never signed anything about a cap. This is bullshit". Their response, check you EULA. I say "thanks", and proceed to do so. 'Lo and behold, it is there. It turns out there is also a line in the agreement that basically says that they can at ANY time add ANY thing to the agreement and they don't really have to notify you. You see because they posted the changed agreement in an obscure URL on their website that i am sure everyone monitors daily. I have had my connection suspended once since then.
Apparently the reason for the "caps" and canceling of service, is that your increased activity (going beyond the cap) MAY indicate that your computer has been compromised by hackers (ohhh noes!) and are now illicitly using your connection for nefarious means, so it only a precaution that it is being disconnected. Once you call in prove, that no it was you they will reconnect you with 1GB worth of cap space, if you go beyond that, they cancel your account for 24 hours and then you can activate for another GB of Cap. If you go beyond that, they cancel you for the rest of the month. The last time I got canceled, I had the one GB cap, and WOW decided to download automatically an 500MB update I was a bit worried.
What really burns me is that they have these cap but offer no way to monitor your cap space. NONE! The only way to check is to call in and ask one of their tech people, and the last time I did that (when I was worried there), they didn't really either know or were not sure.
Now I said to myself that if this happened again I would go someplace else and vote with my money so to speak (been a customer for 10+ years). However all the other ISP's than have no cap limit, all use BELL or Cogeco lines, thus no matter who you go with, if Bell or Cogeco decide to throttle or whatever, all the "compitition" by default will also.
Anyways it is one of those frustrating things, that due to the monopoly there is NOTHING you can do about it. You have two choices: 1) Do whatever Bell and Cogeco say and pay want they want, or 2) Don't have an internet connection.
The only good part about the situation (sorta) is that I did actually learn a lot about the issues, the industry, the alternatives (such that they are), etc.. that I would not have if I wasn't so pissed off that I went on a learning tear.
Anyway I need an internet connection, so I bend over and take it like everyone else.
Adelphia is dead (no more). Are we sure the list is updated beside the history changes? I don't have an account there to fix and not going to do so for one change (already tried BugMeNot).
Ant(Dude) @ Quality Foraged Links (AQFL.net) & The Ant Farm (antfarm.ma.cx / antfarm.home.dhs.org).
The ISP for which I work does no such packet shaping or TCP resetting one any traffic entering or leaving our network. Despite this, we have a median reset rate approaching 13%. Does this plugin take into consideration the fact that the reset could be sent from a foreign network rather than the provider the client is attached to?
Does the Vuze client track resets on a per foreign client basis, or as an aggregate of the local client.
Any insight into this?
[WP:Beans]
-
- - You can't take something off the Internet! That's like trying to take pee out of a swimming pool.
Vuze is gathering statistics of TCP connection disruptions from thousands of P2P users and basing their assumption of bandwidth throttling and filtering solely on those disruptions.
What people don't realize that much of the disruptions are caused by good, old-fashioned sub-par service provision and not throttling or filtering.
I've got a Cogeco 10 Meg connection. I'm totally satisfied with it... most of the time.
Browsing the web, net radio, FTP, etc... super-fast. P2P can be wickedly fast too. BUT, whenever P2P uploads start going (an inevitability on most networks), my connection virtually DIES. Uploads rarely go above 10kb, and most additional connections like web or e-mail will simply stall most of the time, and remain stalled for at least 2 minutes after I disconnect my P2P. (This is even with encryption options.)
That's one of the reasons I dislike BitTorrent. When it's in use, my connection is otherwise useless.
Does it make you happy you're so strange?
Huh? I am a Cogeco customer in Windsor, ON. I download torrents at 700 kB + per second. Yes, that is seven hundred kiloBYTES per second. I have had multiple warning phone calls and e-mails from Cogeco about my downloading, and even had my account suspended for downloading 130 gigabytes in 3 days. They do not throttle, or if they do, they throttle to speeds their customers never reach naturally anyway. And the fact that they haven't simply terminated my service yet speaks to their willingness to tolerate P2P users.
DSL's different, with far more players at different parts of the OSI protocol stack:
- - The dry copper lines are still owned by the monopoly telco,
- - the Layer 2 ATM layer may be provided by telco DSLAMs, or may be provided by DSLAMs owned by carriers such as Covad,
- - Layer 2 concentration from the DSLAM to the router may be provided by the DSLAM provider or the Layer 3 service provider,
- - and the Layer 3 Internet service (including routing, upstream feeds, and extra services such as email and web hosting) may be provided by the DSLAM provider, or may be provided by a third-party ISP such as Speakeasy or Sonic, and the
- - Layer 8 services (financial
:-) may be provided by the ISP or by some aggregator such as Megapath that sells bundles of service from multiple providers.
(There are a few variants on this such as using frame instead of ATM for Layer 2, or using PPPoE to make it easier to handle billing by over-complicating technology, but most of them don't change the fundamental differences in which provider sets which kinds of policies.)Traffic throttling and similar harassment isn't primarily a Layer 2 ATM feature - it's an ISP feature usually handled at Layer 3 or 4 of the OSI stack, though occasionally it's done at higher layers (e.g. some detection mechanism and either TCP RSTs or various ICMP distractions.) The amount of oversubscription that happens at Layer 2 may be handled by the DSLAM provider or the router provider, but that's normally done by assigning some committed bandwidth level to each subscriber and doing some kind of fair-queuing with any excess bandwidth, so it doesn't know or care whether you're running one fat FTP session or videoconference or a Layer-3-fairness-evading bundle of many TCP sessions from Bittorrent.
So if you don't like your DSL provider's policies, whether they're P2P throttling or charging too much for static IP addresses or not allowing you to run servers at home or restricting who you can share your wireless router with or whatever, you can get another ISP that'll provide you better services. You may not get more bandwidth than the vanilla telco DSL services, depending on whether you live in a market with multiple DSLAM providers or how good your copper wires to the telco are, and you won't get the latest loss-leader price, but at least in most of the RBOC-served parts of the US, you can certainly get better policies if you want them. My copper's not great (I think I'm still only getting about 1.5/384), but when I decided I wanted a static IP address, I went with sonic.net, whose acceptable use policies were (approximately) "We're selling you *internet* access, not couch-potato service, so do whatever you'd like except for spamming", plus they were doing some cool wireless things, and I could have gotten similarly open policies from Speakeasy and surprisingly reasonable ones from Earthlink. Sonic's a small provider, so they also have the advantage that if I send them email or call them on the phone, I get a response from an actual human with a clue (though sometimes the clue is "looks like a wiring problem, we'll have your telco check it out", and even then, they get to be the ones hassling the telco to get it fixed.)
