Comcast Realizes Blocking By Protocol Is A Problem; Asks BitTorrent For Some Help

from the took-'em-long-enough dept

Well, well, well. After stubborn silence, non-denial denials, and (finally) a “but we have to!” defense, combined lawsuits and FCC threats, it appears Comcast has realized that its traffic shaping efforts have turned into something of a “rootkit moment.” In an announcement this morning, the company has teamed up with BitTorrent Inc. (the company, not the wider protocol itself) in order to come up with “protocol agnostic” ways to manage its traffic. It’s not giving up on traffic shaping — but it will be based on overall bandwidth use, rather than what applications you’re using. Lotus Notes users rejoice.

Of course, announcements, by themselves, mean nothing. Let’s wait and see what sort of systems Comcast actually puts in place before we judge whether the end result is better or not. Though, it does confirm what we noted recently: this really is a problem that can be solved by technology — which Comcast just didn’t want to implement. Comcast’s unwillingness to come up with a more reasonable technology solution earlier (while Verizon and others have been exploring them) is its own fault. In the meantime, it will be interesting to see if this has any impact on the lawsuits and the FCC investigation. Other than that, let’s see what Comcast actually does (and how upfront they are about it) before saying this is a full win. In the meantime, just getting Comcast to budge a little has to be seen as a short-term victory.

I don’t have trouble downloading with bittorrent and I use Comcast. I’m not a big downloader, mostly just use it for legit stuff like linux ISO’s and eval software. It is still faster to use bittorrent than the http or ftp download mirrors. Maybe I just don’t understand exactly what Comcast is doing.

Whatever it is, they should disclose what they are doing so that the consumer can make an informed choice (if they even have a choice). If you prioritize VOIP traffic, that is fine, just let us know. There may be a few crazies out there that will dump their Comcast service if they knew what was going on, but I doubt it would really have an impact on the bottom line.

“Maybe I just don’t understand exactly what Comcast is doing”

Comcast isn’t doing it everywhere. My packets have never been reset ether but my max download speed has been cut to 1/6th of what it was (was 24Mb down now it’s 4Mb down).

“you prioritize VOIP traffic, that is fine, just let us know”

They don’t want to say that because they only prioritise theirs. Vonage, VoiceWing, Skipe users be damned.

“but I doubt it would really have an impact on the bottom line.”

Not much negative, I’d guess mostly positive. They would be the first ISP to be honest with their clients. But, if they decide to cut my Internet speeds down and packet shape my ports I better see a reduction in price to match my reduction in service.

Anonymous Coward says:

“It’s not giving up on traffic shaping — but it will be based on overall bandwidth use, rather than what applications you’re using.”

The moment that someone who is paying the extra for a 16mbps connection is constantly limited to speeds less than the 6mbps (the cheaper connection) connection, Comcast will end up facing lawsuits

Sean Henry says:

I do not mind traffic shaping IF done in good faith. If the service is advertised as up to 10Mb down and 2Mb up then it better be able to provide it. For services that use real time interactive communication and need a faster rate give ALL the same equal priority (eg. First priority emergency services, second VOIP, third most all other services, last background services like updates.).

So if the network can handle 500 users downloading at 10Mbs at the same time. (The download speed cap will be considered 10Mbs for this example.) If there are 1000 users all downloading at the same time the max speed any user can use during that time would be 5Mbs. For any one using VOip they would get 5-10% more bandwidth to use during that time than other users. Any emergency services would be given the max bandwidth of 10Mbs at all times.

Using a file sharing protocol to share within the providers network should have the cap removed for those transmissions up to the point that it starts to limit transmissions into and out of the providers hub. This will allow for faster transmissions less bandwidth going between providers and less network time being used keeping the network from having a high load for as long of a time.

Re: Sean Henry

As an OC192 that provides 1gbps bandwidth costs appx $1 million per month, in order to fulfill your scenario to guarantee that if someone purchases an “up to” 10mbps circuit, and the ISP or Cable company needs to make sure EVERYONE gets their 10mbps at all times when the network is being maxed, the ISP would only be able to have 1000 customers connected to that OC192.
Now if the OC192 only had 1000 customers connected to it, the cable company would have to charge each customer $1000.00 per month to break even. So to make a profit from it, that would cover all their costs, they are going to need to charge each customer at least $1100.00 per month. Are you willing to pay that much per month Sean Henry to guarantee you get your 10mbps?

Sean Henry says:

Re: Re: Sean Henry

Crap for some reason it did not post all the message but my point was.
1. If you have more than 1000 users on actively using all possible bandwidth then 100 more get on doing the same thing all will be scaled back 10%.
2. All users will not be on at the same time.
3. Most the time when on users are not actually transmitting just like my connection now as I type.

Troll Or Do You Really Think That We Have Choice?

RE #9: “all urban areas have a choice these days”

Bill, um, I live in this boondocks called Silicon Valley, and I’ve been told that we are known, as a region, for those there Internets. Yet I have all of two choices for Broadband, Comcast or AT&T. In my last home in the area, DSL did not reach my house, leaving me one choice.

Whether it’s one or two, I don’t think that quite makes it a competitive market, where providers need relinquish market power, and be ruled by customer demand. Much on the contrary, my degree and training in what is called “Economics” suggested to me that a two-provider market could occasionally be considered an oligopoly. This becomes increasingly likely if there are significant barriers to entry for new competitors.

Those barriers to entry could be things like:
– there is significant capital expense preventing new companies from competing
– there are laws preventing entry (like municipal franchises, spectrum licenses, etc.)
– it is practically improbable to install a competing infrastructure (as in digging ditches along every street in a town for your copper, fiber, or cable).
– there is a powerful lobby from the incumbents giving them preferential treatment form government.
– the incumbents will drop their prices and undercut any new credible threat.

I’m not sure if any of those are ringing a bell with you or not, but to me it’s starting to look a bit like the broadband market is not one rife with consumer choice.

No. I don’t agree. We “vote with our dollars” the same way a Zimbabwean votes with their vote (and that country is dangling a long way under Chad.)

limiting by bandwidth, so now we wont get bandwidt

Sounds like a load … now instead of comcast “trying” to limit people who are downloading pirated media, we get bandwidth limits.. So if I “use” my connection, they will limit it? So http downloads get limited to what ? Loads of bullshit and if Bittorent Inc. suggested it, they should burn in hell too.

Technologcal Solution

It’s a great point, this issue needs a technological solution. Not a political or regulatory one. A lot of these issues are only really understood by network engineers, not lawmakers. They need to have the final say. And from what I’ve read (http://bennett.com/blog/index.php/archives/2008/03/27/new-and-improved-traffic-shaping/) network engineers seem to think this is a good plan. This overheated political posturing doesn’t do anything but hide the real issue. Issues that are technical, not political.

Public Knowledge (user link) says:

This is not a solution

Whatever this deal means, it does not mean that Comcast is out of the throttling business. We at Public Knowledge are still pushing forward with our petition to the FCC to demand that Comcast abide by the FCC principles of network management. More information about our petition can be found at:
