Comments on: Comcast really does block BitTorrent traffic after all

Comcast for months has denied blocking BitTorrent traffic, but new tests show that it takes aggressive filtering steps that AT&T, Time Warner Cable, and Cablevision do not.

General Encryption Best Solution
by Josh Geller October 20, 2007 7:14 AM PDT
I think it's about time we started encrypting all traffic. There's no need to put up with this kind of egregious behavior from a service provider. How can they know which traffic to interfere with if they don't know which is which?

That's where we'll be at the end of the day anyway. There are people there now.

Comcast In Freedom out
by Belo3000 October 20, 2007 7:23 AM PDT
I am angered by CNET's recommendation that we have a tiered pricing structure. I am assuming that CNET is part of the problem and not the solution. Internet pricing is too high as t is. Accessing the internet must be inexpensive and totally unfettered. Anyone recommending the opposite is speaking for these huge media corporation which not only are planning to hike prices of basic information, but limit what sites we go to and what now what we download.
I am ashamed of CNET's behavior of not pushing for fair practices but rather towing the line of these huge multi media corporations as they slowly strangle us.

Do you work for Comcast?
by Belo3000 October 20, 2007 7:27 AM PDT
I am fearful of any comments that side with Comcast. I have to assume that the possibility exists that employees of Comcast or people who are friendly to Comcast will post positive comments because they might be paid or are obligated to Comcast.

Don't use Torrent... but now won't use Comcast
by el1jones October 20, 2007 7:34 AM PDT
Any service that sneaks a limit on the users bandwidth is untrustworthy in my opinion, and I will not deal with a company I cannot trust.
Also if I'm paying for bandwidth, it's MY bandwidth to do with as I please. If I pay for less bandwidth, then I get less, if I pay for more, I get more. If I pay for more, I want to use that unfettered.
Comcast will never see me as a customer.

Guilt by association
by AlecWest October 20, 2007 8:37 AM PDT
I'm a Comcast subscriber. And though, until now, I had nothing technical to back me up, I was certain that Comcast was throttling ... not just Bittorrent traffic but all high-bandwidth traffic.

I shepherd three mirror sites that host files for the Star Trek New Voyages fanfilm project (stnv.net, stnv.us, stnv.org). CBS/Viacom and Paramount have graciously granted the project permission to create and allow access to these fanfilm files as long as the project remains a non-profit endeavor. But most of these files are multi-meg files and some of them exceed 1 or 2 gigabytes.

I've had FTP uploads throttled. And sometimes, FTP downloads are throttled, too. And lately, the New Voyages people have created an official site where high-res versions can be downloaded via torrent. However, while I've heard of a few complaints of throttling regarding torrent downloads, it didn't occur to me to ask the complainer for the name of their ISP. From now on, I will.

I do have other ISP options. Some are faster options but more expensive. Even so, if the throttling of FTP traffic continues ... and if torrent complaints end up being Comcast complaints overall ... I'll consider those options in a heartbeat.

MP3 files, in and of themselves, are not illegal. It depends upon what's in the files. The same is true of torrent files. This guilt by association trip being dumped on people who routinely transfer "legitimate" audio and video files is patently unfair. And if it continues at Comcast, my prediction is that they will not have to worry about it in the future ... a future where customers leave them en masse for ISPs who better respect their customer base.

Comcast is correct!
by webkruzer1 October 20, 2007 8:51 AM PDT
Just because a few hog the bandwidth the rest suffers?

Comcast has the RIGHTS to shape traffic so the rest of the people have decent speed. There is only a finite amounth of bandwidth.

Ya wanna watch movies?
Go to NexFlix and get one in the mail.
Music?
Buy a CD.

Don't like what you read here?
Find another ISP.

There are noting but choices, pick one.

Comcast is NOT correct
by keschrich October 20, 2007 9:03 AM PDT
Comcast does have every right to shape traffic, blah, blah, blah.. HOWEVER: When I signed up for service, I paid for a service purporting to offer me x amount of bandwidth. (Offhand I'm not sure what it is.. for the sake of argument, lets say it was 4MBps). Typically I don't use all of my alloted bandwidth, but if I wanted to, I should be able to use all 4MBps 24/7, because thats what I paid for. If they can't offer it, they shouldn't advertise it.

Your closing comment that "there are nothing but choices" is also off. I live in a metropolitan area, and have 2 choices: DSL or Cable. Because of government granted monopolies, there is exactly one company in my area that offers those services: Comcast for cable, and AT&T for DSL. Although I do not support making network neutrality an issue for the legislature, the idea that we have choice depends on the government not creating monopolies.

Actually, Digital Delivery is happenning now
by ssutor October 20, 2007 9:52 AM PDT
Netflix now delivers movies digitally through direct download and streaming. Itunes, Amazon, Rhapsody and even Napster offer legitimate, for retail purchase, of downloadable music.

The reality of the situation is that digital delivery of media is not a thing of the future. It is happening right now. Bandwidth needs must scale to meet this growing customer demand.

You are correct that Bandwidth is not limitless. However, if you get off of a shared bandwidth solution and onto something with dedicated user thruput (DSL for example) then you will atleast have some control over the bandwidth available to you.

Folks who buy the comcast hype and purchase a shared bandwidth solution will always be subject to these kinds of problems.

Correct, perhaps, but without foresight
by AlecWest October 20, 2007 9:56 AM PDT
webkruzer1,

When's the last time you visited Comcast's website and/or watched Comcast's TV advertising regarding their high-speed Internet product? They first use access to high-speed high-bandwidth Internet as a selling point to attract new customers ... then turn around after the customers sign on and treat them like crap for USING that very same high-speed high-bandwidth access which they themselves advertised.

Even so, Comcast or no Comcast, the wave of the future is in high-speed high-bandwidth Internet access. In my last post to this topic, I mentioned that I shepherded mirror sites for the Star Trek New Voyages fanfilm project ... and that the files I upload/download are high-meg files or even gigabyte-sized files. What I didn't mention is that Star Trek New Voyages has been nominated by TV Guide to receive their 2007 Online Video Award in the Sci-Fi category.

Think about that for a second. Not only has the Internet reached a point where high-speed high-bandwidth "webisodes" of programs are made available to the masses. It's also reached a point where the television industry itself, via TVGuide.com, recognizes these web efforts as a wave of the future ... a wave that will affect ALL Internet providers, not just Comcast.

There was a saying that came out of the 1960s - "Either lead, follow, or get out of the way." If Comcast chooses to ignore the high-bandwidth future of the Internet, perhaps the best advice to give them would be to "get out of the way" and let ISPs that embrace the future take the lead - over ISPs that lack the foresight to embrace that future.
Comcast is NOT Correct!!!
by P1Daniels October 20, 2007 10:51 AM PDT
You would be correct if we were talking about people downloading movies, but we're not. The King James Bible (KJB) download under discussion is both quite small and quite legal. Movies are hundreds of MB's and take quite some time to doenload and most movie downloads are illegal (except porn...or so I hear). The KJB download is 4MB and takes literally seconds on my Comcast Cable modem (11MBPs) right here in Philly. I pay hard-earned money for this service and I expect the people I do business with to not sit behind a lawyer-crafted terms-of-service statements that give them all the options to change the rules in the middle of the game. As far as choice...Comcast is the only cable provider where I live...they own this town and Verizon Fios is not yet here...

All you people who think our market-economy gives you all these options are the corporations favorite customers...Dumb, illiterate, and ready to buy the snake-oil.
Uh...Network Neutrality anyone?
by jcanker October 21, 2007 9:07 PM PDT
"Comcast has the RIGHTS to shape traffic so the rest of the people have decent speed."

Uh, no, they don't, unless it affects the QoS for the rest of the users. (Check the current discussions between the FCC and Congress...) Do you REALLY mean to try to convince me that torrent files, regardless of size, are affecting the speed of your email downloads? I can load up a DVD ISO onto my PC, send a link to my friend, and have him download the entire 4.7 GB image, whether it's a movie or just a data backup of a portion of my C: drive. That's okay, but if I send it up as a torrent, which is usually a compressed file, then it's not okay. Hrm....seems like the policy lacks a bit of forethought...

Consider this: Most ISP's incorporate a usage allotment: I get to transfer so much data each month, and if I go over that, then I have to pay extra. What does it matter HOW I use that allotment? Now, don't confuse that with bandwidth, which is how much data I can transfer at a particular point in time. If you don't want me using an 8MB bandwidth connection, then don't sell it to me. If you can't handle the total bandwidth on your global network, then don't offer to let the users claim such a big slice of the pie in the first place. Any ISP oversells their networks the same way most airlines oversell their flights--ISP's don't expect all the users to be using the network at the same time. In order to make you happy, webkruzer1, what Comcast really should do is mandate what timeframe I can log on and use my "always on" broadband so that they can schedule network usage.

Your frustration is misdirected by claiming "Comcast is correct." They AREN'T correct, because they are throttling by content, not by size. They already have the 2 necessary tools in place to limit my use if they want: A specific max bandwidth definition (8mb in my case) and a monthly usage allotment (haven't bothered to look up what it is for Comcast). So, since those are in place, please explain to me why they need to look at my IP headers to see what is actually in the legal data packets that I'm sending to ensure it didn't originate from a peer-to-peer network?

And before you post up again that someone's Netflix download is cramping your style, please take the time to understand the complexities of the Internet beyond logging into your NetZero account to go "webkruzing."
Your not looking at the whole picture!
by klassie1 October 21, 2007 9:11 PM PDT
You need to look at the broader side of things. You are right they do have a finite amount of bandwidth that should be divided upon their subscibers in a fashion that does not cause your neighbors bandwitdh to suffer because you are using 100% of the bandwidth that you were sold. For instance say there backbone could handle(simple math)100Mbps and they had 100 customers, that is enough for each customer to have a reliable (minus tcp/ip overhead and such) 1Mbps without affecting another users bandwidth. Instead they sell that 100Mbps to 400 customers and tell them all that they have a solid 1Mbps connection and hope like hell everyone doesn't use it at the same time. So if they would actually sell service that they could provide this would be a non issue.

They don't block it, typical CNET ignorance and sensationalism
by The_Decider October 20, 2007 9:47 AM PDT
If they were its users could not use bit torrent on Comcast's networks at all.

I have no doubt that they use QOS to throttle things like bit torrent. It isn't that huge of a deal.

People who have cable broadband have to share the network with many services and most need higher priority then what downloading needs.

People watching TV in your network need real time service.

People watching stuff on demand need real time service.

People using VOIP need real time service.

Then there are all the people surfing the net, some with real time needs.

All of these activities take place on the same network.

That is the problem with cable. Essentially it is a shared connection and for many of their services, comcast is able to perform QOS on the entire distance between you and where the content resides(cable, on demand). Why do you think VOD over cable is superior to VOD across the internet? But there is a cost to all this QOS, some services get throttled.

I don't know for sure, but I bet those that are experiencing bit torrent throttling live in areas where there are too many people, doing too many things over a distribution network and something has to give. Downloading is not high priority.

This is one of many reasons why I have DSL.

It's not QOS
by ssutor October 20, 2007 10:07 AM PDT
QOS only classifies and prioritizes traffic thru a network. Comcast is proxying the traffic and sending gratuitous RST packets to the server on behalf of the client to kill the connection.

Slowing traffic and Resetting a session are completely different things.

You are right, however, DSL is the answer and always was.

RE: Downloading is not high priority.
by starcannon October 20, 2007 10:55 AM PDT
The entire concept of the internet relies on the concept of downloading and uploading being a priority.
The article states they tried sharing the torrent on 4 different cable networks with only the comcast network showing evidence of throttling.
Some further tests could have been done, such as testing the sharing of the file over Kazaa or through email, or through instant messaging, or through an ftp service, or from an http address, and honestly it should have been tested out to this degree, so as to really make sure that torrents and or p2p clients in general were being targeted by comcast.
But the initial results are not looking great, looks to me like comcast has some splainin' to do.

Creating Resistant Strains
by p40tomahawk October 20, 2007 9:49 AM PDT
Congratulations, Comcast: you have just guaranteed that the next step in the P2P arms race will consist of block-resistant hidden BitTorrent schemes. Anyone noticing what's happening with Staph bacteria lately? It's precisely the same mechanism, and precisely the same result.

Blocking Napster was dead simple. Today's P2P protocols are far more robust, and now they are going to get even stronger. Simple evolution at work through natural selection.

Comcast blocking traffic
by Bubulus October 20, 2007 9:54 AM PDT
Comcast had better be careful. The common carrier rules cut both ways. The same rules that limit Comcast's liability for carrying, for instance, child pornography traffic also require that they not discriminate in this way. Otherwise they risk losing the legal protection of the common carrier rules and become subject to criminal and civil prosecution for carrying kiddie porn.

God raises cosmic intellectual property awareness

In a court case of biblical proportions, God has passed judgment on the illegal sharing of his written word over the popular bit torrent p2p network.

In press releases given out by his Son and right hand man, Jesus told reporters early Friday that "bible pirates may find themselves in literally a hell of a lot of trouble if they do not cease and desist in unauthorized uploads of the bible either in whole or in part".

Asked whether any of these new revelations on intellectual property would be included in future editions of God's infallible word St. Peter said that "while there are not plans to add or subtract from the books of the Bible its author reserves the right to do so at anytime he sees fit."

Meanwhile advocates for the rights of free will were protesting this development, Judas if Iscariot said "This is exactly the sort of judgment and arbitrary decision making process that had me taking the 30 silver pieces and leaving the Gospel Corporation and Joining the 'Do as thou will' group these two thousand years ago.

The consumer base seems overwhelmingly split, while some believe deeply that the word of God should be freely available and distributable in every language around the planet, others point to the omnipotence and profound wrath of God when he is angered.

Comcast blocking small files too.
by dlockling October 20, 2007 10:32 AM PDT
A friend tried to forward an article to me to my comcast account, it was returned to him as spam. We email regularily, so he is not block by me as a spammer. I asked him to send to another email account through a different provider, and it came through. Coincedence - I don't think so. Since the article was political in nature, it leads one to believe that political speak is being targeted by comcast as well. Are these issues that can be built into a class action lawsuit? I hope so.

by The_Decider October 20, 2007 10:38 AM PDT
It is not a coincidence but it is not some grand conspiracy either.

Some ISP's treat emails from certain email providers as spam by default.

Set up your own mail server and try to send email to a provider like hotmail, without properly configuring it for hotmail. Unless you alter some settings hotmail will block you.

Have him send an encrypted email to you from the account that was marked as spam and you will see that your paranoid, ignorant theory holds no water.
Legitimate Large Files
by starcannon October 20, 2007 10:45 AM PDT
I run Linux exclusively, when a new release comes out the torrent network is often the fastest way to download the new release iso.
Fortunately I have a great ADSL provider, I'd be pretty disgruntled if my torrents were being throttled.
The fix is easy here folks, simply switch to a provider who does not mess with your bandwidth.
Do not give money to those who would unjustly attempt to limit bandwidth use, freedom of speech, or any of the other freedoms we enjoy through use of the internet.
It's your dollar, spend it wisely

Net neutrality has nothing to do with this
by The_Decider October 20, 2007 11:45 AM PDT
Comcasts networks are private. Net neutrality has to do with the internet "backbone" and whether or not packets should be prioritized there(they should not be). But that is a different issue from the one covered(very poorly) here.

Before anyone suggests, I am not a Comcast shill, I just don't like people missing the point and suggesting things like censorship when that is not the issue. Comcast is a private network, not really any different then the network at your place of business.

If you have read my posts here on CNET, you would never take me for a corporate shill. I am not anti-corporate either, just pro-corporate responsibility and think that corporate interests should never trump individual, environmental, etc interests.

Every six months or so, I always shop around to see if I can find cheaper auto insurance than my current insurer provides. But until I read your article, it hadn't occurred to me to shop around to see if I could find a cheaper ISP.

I'm a Comcast subscriber in Portland, Oregon. And today, I searched around for a different provider. I didn't want DSL because I didn't want to be forced into maintaining a landline to get the service ... especially since I use a broadband phone (Packet8.net). So, wireless was my only option.

Well, as it happens, I found a wireless service right here in town that offers the same download speeds I experience with Comcast, faster upload speeds than I experience with Comcast, and after the initial startup costs are out of the way ends up costing me $11 per month LESS than Comcast ... even less if I pay their yearly fee upfront.

Mind you, I hardly every use a torrent utility. Most of my bandwidth use comes from watching online video streams and FTPing. But it just goes to show that no matter what kind of service you can think of, it can pay off handsomely if you "shop around" from time to time. And, I get the feeling this effort will pay off for me (grin).

Again, thank you Declan McCullagh.

Death From Above, 2.0
by metavalent October 20, 2007 6:58 PM PDT
Um, or just build the REQUIRED CAPACITY in the first place? The New First Mile Oligarchs are pretending like bandwidth is a scarce resource; it is only as scarce as their refusal to build the required capacity. The oligarchs said that we couldn't have local loop competition because there would be no business model to meet the DEMAND; now, they are failing to meet that market demand, having killed off competition.

Comcast and AT&T have been NEGLIGENT in failing to fulfill their oligarchical market duties, in many cases flat illegally acting to prevent the Telecom Act of 1996 from succeeding and rebuilding the Death Star; despite both MARKET and REGULATORY requirements to be OPEN and COMPETITIVE.

This was not at all unforeseeable. There were plenty of us as early as the 1990's saying BUILD THE OPEN ACCESS GIGABIT ETHERNET LOCAL LOOP. Even the IEEE ratified an Ethernet in the First Mile STANDARD! But the self-proclaimed visionaries of Sand Hill Rd. and Wall Street said, "what would anyone ever need all that bandwidth for?"

So, to cover their own short-sighted tracks, the game is calling Power Users and Leading Innovators "bandwidth hogs."

They aren't "hogs" ... they are POWER USERS ... you know, the kind of people who maximize utility of available resources to bring you the Next Great Things. Pretty soon, what was only for the power users is available to everyone. Killing that dynamic is killing innovation.

John Perry Barlow told us all about this in 1995. He called it Death From Above. http://tinyurl.com/2tuakm

This current assault on innovation is nothing more and nothing less than Local Loop Death From Above 2.0: Terror of the New Oligarchs.

Not to mention Korea
by metavalent October 20, 2007 7:10 PM PDT
And many other nations where RESIDENTIAL users pay $20/mo. or less for 100Mbps or more!

The UK gets this and the US better wise up, right now. "The minister contrasted the UK's lack of broadband offering speeds of more than 20Mbps with South Korea, where he said 90 percent of homes now had broadband connections offering 50 or 100Mbps."
SOURCE: http://tinyurl.com/ywfvgz

Of course, the obligatory troll may tell me, "then move to Korea if you don't like America," but that's not the point. The point is, if the biggest economic power in the world can't also provide the best Universal Ethernet network in the world, it won't remain in that leadership position for long.

ATT.com also get dropped!
by DMAN3k October 22, 2007 10:31 AM PDT
Recently, when I check my ATT (Cingular) Wireless service on the web, I noticed that my internet died. After clicking refresh like 10 times, the site finally shows up.

Is Comcast limiting connections to ATT.com?

I called support and they send a "network engineer" over the phone to talk to me. I asked them about bandwidth cap, ATT.com, and legitimate p2p (bit torrent). He said that there is a bandwidth cap but from what he could tell, I'm not reaching it. He also denies Comcast blocking ATT or any p2p. However, when I asked him if this is just what the company allows him to say, he said," Yes." Then I ask him, "What would YOU say?" He replied, "I cannot answer that question."

This is the reason why we need Net Neutrality.

More to consider...
by phonebem October 22, 2007 3:24 PM PDT
Not to sound too paranoid, but has anyone thought of this as a monopolistic move? It may sound strange but hear me out... Comcast in addition to internet offers pay per view movies through their cable service. I'm curious as to how Comcast would view the bandwidth consumed by, say a media center PC streaming a DVD quality video LEGITIMATELY from Netflix online, or a comparable service. This is direct competition for Comcast's ppv service and I'm pretty sure that this would be a legal loophole to fight Comcast on this one regardless of any "terms of service agreement". Please correct me if I'm wrong but, I don't think that type of agreement can be used to restrict competition. This isn't even taking into consideration the legal music streaming sites in existence which could (would) also be restricted. I guess in short this could be significantly more underhanded than it appears on the surface...

bandwidth

you get what you pay for..?

Folks that's what its all about.

IF you sign a contract with your Service Provider and it states say 8Mbps downstream to your computer/home and states that you can transmit say 768Kbps upstream to the internet.....

What Part of that CONTRACT is misunderstood?
By EITHER the provider or the consumer??

If I pay for 8Mbps down and 768kBps up... I DO NOT care and neither should the Service Provider care if that means 24x7... it should be priced appropriately based on competition and profit requirements.
