Growing questions are being raised about whether Comcast is violating FCC and Department of Justice policies that prohibit the cable company from prioritizing its own content traffic over that of its competitors.

Comcast’s Xfinity Xbox app offers Comcast customers access to Xfinity online video content without eating into their monthly 250GB Internet usage allowance. Netflix has called that exemption unfair, because its content does count against Comcast’s usage cap. New evidence now suggests Comcast may also be prioritizing the delivery of its Xfinity content over other broadband traffic, a true Net Neutrality violation if proven true.

Bryan Berg, founder and chief technology officer at MixMedia, believes he has found proof the cable company is giving its own video content preferential treatment, in this somewhat-technical finding published on his blog:

What I’ve concluded is that Comcast is using separate DOCSIS service flows to prioritize the traffic to the Xfinity Xbox app. This separation allows them to exempt that traffic from both bandwidth cap accounting and download speed limits. It’s still plain-old HTTP delivering MP4-encoded video files, just like the other streaming services use, but additional priority is granted to the Xfinity traffic at the DOCSIS level. I still believe that DSCP values I observed in the packet headers of Xfinity traffic is the method by which Comcast signals that traffic is to be prioritized, both in their backbone and regional networks and their DOCSIS network.

Berg also contends Comcast’s earlier explanation that its Xfinity content should be exempt from its usage cap because it travels over the company’s private Internet network is also flawed:

In addition, contrary to what has been widely speculated, the Xfinity traffic is not delivered via separate, dedicated downstream channel(s)—it uses the same downstream channels as regular Internet traffic.

Berg

Broadband traffic management is of growing interest to Internet Service Providers, who contend it can be used to manage Internet traffic more efficiently and improve speed and time-sensitive online applications like streamed video, online phone calls, and similar services. But manufacturers of traffic management equipment also market the technology to ISPs who want to favor certain kinds of content while de-prioritizing or even throttling the speed of non-preferred content. The technology can also differentiate traffic that counts against a monthly usage cap, and traffic that does not.

Quality of Service (QoS) technology can be used to improve the customer’s online experience or help a provider launch Internet Overcharging and speed throttling schemes that can heavily discriminate against “undesirable” online traffic.

Berg further found that when he saturated his 25Mbps Comcast broadband connection, traffic from providers like Netflix suffered due to the bandwidth constraints.  Because he flooded his connection, Netflix buffered additional content (slowing his stream start time) and reduced the bitrate of the video (which can dramatically reduce the picture quality at slower speeds). But when he launched Xfinity video streaming, that traffic was unaffected by his saturated connection. In fact, he discovered Xfinity traffic was exempted from his normal download speed limit, allowing his connection to exceed 25Mbps.

While that works great for Xfinity fans who do not want their videos degraded when other household members are online, it is inherently unfair to competitors like Netflix who are forced to reduce the quality of your video stream to compensate for lower available bandwidth.

According to the consent decree which governs the merger of the cable operator with NBC-Universal, prioritizing traffic in this way is a no-no when the company also engages in Internet Overcharging schemes, namely its arbitrary usage cap:

“If Comcast offers consumers Internet Access Service under a package that includes caps, tiers, metering, or other usage-based pricing, it shall not measure, count, or otherwise treat Defendants’ affiliated network traffic differently from unaffiliated network traffic. Comcast shall not prioritize Defendants’ Video Programming or other content over other Persons’ Video Programming or other content.”

This graph shows Berg's artificially saturated 25Mbps Comcast broadband connection. The traffic in red represents Xfinity Xbox traffic, which is given such high priority, it allows Berg to exceed his usual download speed limit.

Comcast sent GigaOm a statement that denies the company is doing any such thing:

“It’s really important that we make crystal clear that we are not prioritizing our transmission of Xfinity TV content to the Xbox (as some have speculated). While DSCP markings can be used to assign traffic different priority levels, that is not their only application – and that is not what they are being used for here. It’s also important to point out that our Xfinity TV content being delivered to the Xbox is the same video subscription that customers already paid for and is delivered to their home over our traditional cable network – the difference is that we are now delivering it using IP technology to the Xbox 360, in a similar manner as other IP-based cable service providers. But this is still our traditional cable television service, which is governed by something known as Title VI of the Communications Act, and we provide the service in compliance with applicable FCC rules.”

Our View

Comcast, as usual, is talking out of every side of its mouth. In an effort to justify their unjustified usage cap, they have pretzel-twisted a novel way out of this Net Neutrality debate by paving their own digital highway on a Comcast private drive.

Comcast argues their 250GB usage cap controls last-mile congestion to provide an excellent user experience. That excuse completely evaporates in the context of its new toll-free video traffic. In fact, their earlier argument that its regionally-distributed streaming traffic should not count because it does not travel over the “public Internet” at Comcast’s expense does not even make sense.

Berg provides an example:

A FaceTime call from my house to my neighbor’s—which never leaves even the San Francisco metro area Comcast network, given that both of us are Comcast customers—goes over the “public Internet.”

Yet Comcast’s Xbox streams, which pass from Seattle to Sacramento to San Francisco through all of the same network elements that handle my video call (and then some!) are exempt from the bandwidth cap?

You can’t have it both ways, guys.

DOCSIS 3 technology has vastly expanded the last mile pipe into subscriber homes. If Comcast can launch their own private pipe for unlimited IPTV traffic that travels down the same wires their Internet service does, they can comfortably handle any additional capacity needs to support their “constrained” broadband service without the need to limit their customers’ use.

Usage caps remain an end run around Net Neutrality. Consumers given the opportunity to view content under a usage cap on the “public Internet” or using the “toll-free” traffic lane Comcast created for content from their “preferred partners” will make the obvious choice to protect their usage allowance. Comcast is certainly aware of this, and it is a clever way to discriminate through social engineering. It’s also less obvious. You don’t have to de-prioritize or block traffic from your competition to have an impact, you just have to limit it. Customers who repeatedly exceed their usage allowance face suspension of Comcast broadband service for up to one year. That’s a strong incentive to follow their rules.

Netflix is fighting to force Xfinity traffic to fall under the same arbitrary usage cap regime Netflix endures — a truly shortsighted goal. The real issue here is whether Comcast should be capping any of its Internet service.

Comcast has given us the answer, launching the very bandwidth-intense video streaming it used to decry was contributing to an Internet traffic tsunami.

It’s time for Comcast to drop its usage cap.

Shaw Cable has pulled the plug on its complimentary cable radio service on Vancouver Island, which used to provide enhanced FM reception of radio services from across the province and from the United States.

Listeners in the Vancouver area never received notification the service was being terminated, and a Shaw spokesman said the company did not bother because it was a free service delivered to cable customers.

Some listeners called the loss of more than 20 FM stations devastating, leaving them with as few as three clear stations, and no reception of CBC Radio 2 from Canada’s public radio network.

Kerry Hunt, Shaw’s regional manager for Vancouver Island, said the company is phasing out the FM radio service in order to increase Internet speeds and make room for additional digital cable channels.

“Nobody is installing FM anymore,” Hunt told Canada.com. “It’s just a service that is very rarely even being used.”

Gone for some B.C. listeners

Hunt called cable radio anachronistic in the digital and Internet age, and those customers who value the service are now being pushed to use Internet streaming services, offered by many of the stations listeners lost. But those streams count against the company’s Internet Overcharging usage caps, and with many of cable radio’s fans among the less-computer-savvy elderly, the expense to add broadband service to continue listening to radio stations they used to receive for free is a hardship.

Cable radio service is a legacy service, originally introduced in the 1970s and 1980s to provide enhanced radio service to cable-TV subscribers over cable-wired FM receivers. Some cable systems delivered national radio superstations, college stations not available over the air, or distant regional radio signals not well received by cable subscribers.

The Canadian Radio-television and Telecommunications Commission used to require all Canadian cable operators provide the service, converting all area AM signals for FM reception. Those rules have been considerably relaxed, and today most cable operators deliver the bare minimum, including one CBC Radio service, over its set top cable boxes.

Shaw says it plans to gradually discontinue cable radio service across its entire coverage area.

After intense lobbying, wireless phone companies won a significant reprieve from the watered-down 2010 Net Neutrality policies introduced by Federal Communications Commission chairman Julius Genachowski.

Now some of America’s largest cell phone companies are considering plans that would offer special “toll-free” access to favored partners’ content, while leaving everyone else subject to the companies’ usage capped data plans.

Much of the discussion about exempting certain content from data allowances is taking place at this week’s CTIA Wireless trade show in New Orleans.

Some highlights:

• T-Mobile USA is planning to expand video streaming services offered to subscribers, but with a twist. Content creators could pay to have their shows streamed to customers, and in turn, T-Mobile would not charge that traffic against the customer’s monthly usage allowance. Whether T-Mobile would maintain an ownership interest in the content is unknown, but “preferred partners” would receive exceptional visibility through aggressive promotional campaigns T-Mobile would launch.  So would T-Mobile, which plans advertising and promotional messages inside that content;
• Verizon Wireless said it was looking to create “toll-free” data services that would be subsidized by content providers. Video, games, and even apps could be promoted to consumers as “data usage”-free, meaning it won’t count against your monthly usage allowance. But Verizon recognizes the concept would be controversial and run afoul of Net Neutrality concerns.
• AT&T has already signaled its interest in creating a “content-provider-pays” model where users get free access to content if content providers pay AT&T’s traffic charges.

All three carriers earlier abandoned all-you-can-eat flat rate data plans, and Net Neutrality proponents claim these latest moves are attempts by wireless phone companies to further monetize data traffic.

The Wall Street Journal reports the plans, in some cases, fly in the face of rhetoric about spectrum shortages and a wireless data traffic crisis (underlining ours):

T-Mobile’s Mr. Duea said the goal of new video offerings that don’t count against data plans would be to get customers interested in consuming more data, and set T-Mobile’s plans apart from those of other carriers.

"Data floods" and "spectrum shortages" don't stop T-Mobile.

Current FCC Net Neutrality rules require wireless carriers to not block competing services from companies like Skype and Google, nor censor content. Both Verizon and MetroPCS are challenging those rules in federal court. But wireless carriers are already exempt from giving preferential treatment to certain types of data or traffic, which opens the door to “toll-free” data services.

Net Neutrality supporters believe these practices will uneven the playing field for content creators and innovative new online start-ups, who may not be able to afford the prices carriers charge for first class treatment. It also influences consumer decision-making by encouraging customers to use the “toll-free” services to preserve their monthly data allowance.

Companies like Ericsson and Cisco have plans to market technology that will allow carriers to divide up data traffic into different traffic lanes, some fast and free to use, others subject to a customer’s monthly data allowance, and certain undesirable traffic shunted to low priority slow lanes.

A Verizon Wireless executive ironically blamed the need for “toll-free” pricing partly on the wireless industry itself, which has almost universally abandoned unlimited data plans.

“As we move away from flat rate pricing, there is room for an 1-800-type of service where certain destinations could offset the cost of the network to get customers to those destinations,” said Verizon’s chief technology officer Tony Melone. “There are Net Neutrality issues that have to be addressed, too.”

Melone added the company wasn’t quite ready to launch the “toll-free” traffic lanes just yet, but claimed certain content providers were discussing deals with the company to participate if and when the new toll booths are opened for traffic.

Wall Street analysts are predicting the end of free video streaming in the near-term as media and cable companies regain control over online content for themselves.

Cable companies are partnering with content producers to move a growing amount of streamed video content behind paywalls in an effort to protect their core business profits.

The trend is evolving so rapidly, analysts like Laura Martin with Needham & Co. predict the end of free streaming is imminent.  Either customers will pay upfront or use TV Everywhere “authentication platforms” that require evidence of a pay television subscription before being able to watch.

Craig Moffett, an analyst with Sanford Bernstein, perennially sees cable operators as the most likely winners in the billion-dollar entertainment battle.

“They’re winning the broadband wars,” Moffett says of the cable industry. “Broadband is increasingly the flagship product, not the video distribution business.”

Cable networks and program producers are growing increasingly alarmed at the impact video streaming services like Hulu and Netflix are having on their bottom lines.

Case in point: the fall of Nickelodeon, a popular children’s cable network that used to guarantee high ratings and lucrative ad revenue.  Recently the network has fallen off the ratings cliff.  Some careful analysis found the reason why: Netflix.  Nickelodeon, along with many other cable networks, licensed a number of their series to Netflix for on-demand viewing. In households with young children, parents increasingly choose the on-demand Netflix experience for family viewing over the traditional cable channel.

Moffett

That’s a major problem for content producers and networks, and Moffett quotes industry insiders who predict licensing deals for Netflix streaming will increasingly not be renewed (perhaps at any price) as networks retrench to protect their core business.  What is left will soon be behind paywalls, limited to customers who already subscribe to a pay television service.

That line of thinking is already apparent at Time Warner (Entertainment), Inc., where CEO Jeff Bewkes rarely has a good thing to say about Netflix.  His company refuses to license a significant amount of their content for online streaming because it erodes more profitable viewing elsewhere.

Time Warner only licenses older content and certain “serialized dramas” that have proven difficult to syndicate on traditional broadcast television or cable outlets.  But the company keeps kid shows to itself and its own distribution platforms, like Cartoon Network.

When it does let shows go online, it wants them behind paywalls.

Bewkes applauded Hulu’s recently announced plans to move its service away from free viewing.  Authenticating viewers as pay TV subscribers before they can watch “makes sense” to Bewkes.

“Hulu is moving in the right direction now,” Bewkes said.

Big media companies do not want significant changes to the viewing landscape, where major networks front the costs for the most expensive series, and cable networks commission lower budget programs and repurpose off-network content.  Pay television providers bundle the entire lineup into an enormous package consumers pay to receive. That is the way it will stay if they have their say.

“Just because consumers would rather get individual channels a-la-carte, on-demand, and streamed — only what they want to pay for — [if they think] that is inevitably the way the world if going to evolve, not so fast,” Moffett said. “It may be the way consumers want it and it may be the way technologists want it, but the media companies have a say here.”

“There is no way they are going to voluntarily unbundle themselves,” Moffett said.

Comcast Monday announced it was exempting its new Xbox streaming video service from the company’s long standing 250GB monthly usage cap, claiming since the network doesn’t exist on the public Internet, there is no reason to cap its usage.

Net Neutrality advocates immediately denounced the cable operator for violating Net Neutrality, giving favorable treatment to its own video service while leaving Netflix, Amazon, and others under its usage cap regime.

Public Knowledge president Gigi Sohn:

“The Xbox 360 provides a number of video services to compete for customer dollars, yet only one service is not counted against the data cap—the one provided by Comcast.” Sohn said. “This is nothing less than a wake-up call to the Commission to show it is serious about protecting the Open Internet.”

Stop the Cap! believes Comcast also inadvertently undercut its prime argument for the company’s 250GB usage cap — that it assures “heavy users” don’t negatively impact the online experience of other customers:

We work hard to manage our network resources effectively and fairly to ensure a high-quality online experience for all of our customers. But XFINITY Internet service runs on a shared network, so every user’s experience is potentially affected by his or her neighbors’ Internet usage.

Our number one priority is to ensure that every customer has a superior Internet service experience. Consistent with that goal, the threshold is intended to protect the online experience of the vast majority of our customers whose Internet speeds could be degraded because one or more of their neighbors engages in consistent high-volume Internet downloads and uploads.

The threshold also addresses potential problems that can be caused by the exceedingly small percentage of subscribers who may engage in very high-volume data consumption (over 250 GB in a calendar month). By applying a very high threshold on monthly consumption, we can help preserve a good online experience for everyone.

Comcast argues around the exemption of the Xbox service by reclassifying it as somehow separate from the public Internet.  The company then tries to claim the Xbox app functions more like an extra set top box, not as a data service.  But, in fact, it –is– a data service delivered over the same cable lines as Comcast’s broadband service, subject to the same “last-mile congestion problem” Comcast dubiously uses as the primary justification for placing limits on customers.

Cable providers who limit broadband use routinely use the “shared network experience” excuse as a justification for usage control measures.  Since cable broadband delivers a fixed amount of bandwidth into individual neighborhoods which everyone shares, a single user or small group of users can theoretically create congestion-related slowdowns during peak usage times.  Cable operators have successfully addressed this problem with upgrades to DOCSIS 3 technology, which supports a considerably larger pipeline unlikely to be congested by a few “heavy users.”

Comcast’s argument the Xbox service doesn’t deserve to be capped because it is delivered over Comcast’s own internal network misses the point.  That content reaches customers over the same infrastructure Comcast uses to reach every customer.  If too many customers access the service at the same time, it is subject to precisely the same congestion-related slowdowns as their broadband service.  Data is data — only the cable company decides whether to treat it equally with its other services or give it special, privileged attention.

Even if Comcast argues the Xbox streaming service exists on its own segregated, exclusive “data channel,” that represents part of a broader data pipeline that could have been dedicated to general Internet use.  The fact that special pipeline is available exclusively for Comcast’s chosen favorites, while keeping usage limits on immediate competitors, is discriminatory.

Comcast customers who have lived under an inflexible 250GB usage limit since 2008 should be wondering why the company can suddenly open unlimited access to some services while refusing to adjust its own usage limits on general broadband service.

Stop the Cap! believes Comcast has forfeit its own justification for usage caps and network management techniques that can slow customer Internet speeds.  We have no problem with the company offering unlimited access to the Xbox streaming service. But the company must treat general Internet access with equal generosity, removing the unjustified and arbitrary usage cap it imposed on customers in 2008.  After all, if the company can find vast, unlimited resources for a service it launched only this year, it should be able to find equal resources for a service it has sold customers (at a remarkable profit) for more than a decade.

Anything less makes us believe Comcast’s usage caps are more about giving some services an unfair advantage — violating the very Net Neutrality guidelines Comcast claimed it would voluntarily honor.

Stop the Cap! strongly believes usage caps are increasingly less about good network management and more about controlling and monetizing the online experience, seeking marketplace advantages and new revenue streams from consumers who already pay some of the world’s highest prices for broadband service.  As we’ve argued since 2008, Internet Overcharging through usage caps and usage based billing is also an end run around Net Neutrality.  The evidence is now apparent for all to see.
