Comcast’s New Traffic Meter Makes Customer The Traffic Cop; Admits Up to 1GB Represents “Background Traffic”

Comcast's new usage gauge is being tested in Oregon

Comcast's new usage gauge is being tested in Oregon

Comcast’s long promised “usage gauge” has arrived.  The company promised to provide one to customers more than a year ago when it imposed a 250GB monthly usage limit on its residential broadband accounts.  Although generous in comparison to some other providers that limit customers to as little as 1-5GB of usage per month, Comcast’s allowance and the meter re-emphasizing it has created controversy among customers concerned about usage caps, potential overlimit fees or speed throttles.

Stop the Cap! reader “bones” sent along word of the measurement tool beta test in the Portland, Oregon area, and reviewing the accompanying data exposes some inconvenient facts such usage limits will have on customers.

Comcast’s version of the ‘gas gauge’ depicts usage on a bar graph and is updated monthly.  Company officials claim the average user consumes just 2-4 gigabytes per month, a debatable figure.  Comcast claims about 1% of their subscribers exceed 250GB of usage per month, but does not indicate whether that number has been on the increase as the company unveils new premium speed, premium priced broadband tiers.

Comcast hired NetForecast to “independently” verify the accuracy of the meter, which they claim produces results within 0.5% accuracy.

The company’s report concludes with praise for Comcast’s new meter, claiming it “will shine a new light on a previously unknown and misunderstood aspect of the digital age. NetForecast believes that this information will allow consumers to become better informed, and better informed consumers will help positively shape the Internet’s future.”

It also increases resentment towards a company that makes them check a meter to be sure they are within their “allowance” for the month, particularly when that company makes loads of money on broadband service.

NetForecast’s tests do reveal several new pieces of information to the “net meter” controversy:

  1. The company found up to 1GB of traffic per month represented “background traffic associated with modem management.”  That’s a considerable amount of data counted against a customer’s usage, especially for customers stuck on lower consumption usage plans;
  2. The increasing complexity of some web pages and their underlying structure can contribute to additional traffic associated with “protocol overhead”;
  3. Poorer line quality can result in increased traffic due to retransmission requests;
  4. “Unexpected” traffic is so substantial, it warranted its own section in the NetForecast report:

Traffic can be generated by more than just PCs. Any device that has access to the wireless router is a potential Internet traffic generator—including smart phones, game consoles, digital video recorders, printers, cameras, etc. Many non-PC devices “phone home” to a manufacturer or supporting service. These automated connections are transparent to the user as a convenience so the user is unaware of the traffic generated.

The most likely source of unexpected traffic, however, is from software running on PCs throughout the home. The Windows operating system and most popular software have automated update programs. These updates often download and are installed automatically without the need for user intervention. The automation is generally designed for the convenience and protection of the consumer, but the traffic it generates may come as a surprise.

Each program update download may be modest in size, however, when you multiply a modest download by the number of programs calling for updates and the number of PCs in the house, the traffic attributable to updates can be substantial. Furthermore, in some cases the vendor default update settings are very aggressive, with some default settings checking each hour and downloading every possible option even though they are not all needed. For example, a software program may load its interface in a dozen languages even though all household members only know how to read English.

That’s just the beginning.  The company also documented “surprise usage” from smartphones downloading updates, photo sharing sites, online backup, and other online applications.  Perhaps most important are online video services:

A large volume of traffic may be going to digital video recorders such as TiVo. A user in the home may have rented a movie from Amazon, Netflix. Blockbuster, etc. Renting the movie will be a known traffic-generating event, however, many services also preload the start of other movies as well as trailers to make them instantly available should they be called for. As in other situations described above, traffic is consumed for the consumer’s convenience but without his or her knowledge.

If Comcast’s meter results showing your usage doesn’t make sense and you don’t believe or understand the numbers, wait until you read how it is your responsibility, as a customer, to do all the sleuthing.

NetForecast’s prescription for “rogue traffic” requires the customer to shut off their computers and other connected devices for a “digitally silent” period (overnight or on a weekend when traveling).  Then, the customer gets to follow this routine:

At the end of the digital silence turn on one PC and log back into the Comcast meter portal, or you can check from an Internet cafe or other means while you are away. If true digital silence was achieved, the meter should not have incremented by more than 1GB. If there is more than 1GB use over even several days, then there is certainly some other traffic consumer connected through the router.

If the digital silence experiment worked, then carefully add devices back to the home network while watching the meter. Note that the meter only increments once per hour, so it may take some time to find a rogue traffic source. On the other hand, the home may simply be a highly connected place that is leveraging many aspects of the Internet, and the traffic may be entirely due to legitimate use.

“I guess those of us who are Comcast customers get to add this to our ‘list of things to do’ when we are trying to enjoy our broadband service,” writes Stop the Cap! reader Karen in Portland.  “Can you imagine telling a customer whose wireless wi-fi was ‘borrowed’ by a neighbor that they have to do all this when half the time, those customers don’t even understand how to enable wi-fi security?”

Each and every byte gets counted.  Almost.

Exempt from the usage meter are Comcast’s digital phone service and on-demand video services sent to your television. That’s a nice benefit for Comcast, but not so nice for their competitors, such as voice-over-IP telephone services and the aforementioned Netflix, Amazon, and other on-demand broadband video services. Programming sent to your computer over Comcast’s forthcoming TV Everywhere service does count against your allowance, however.

With a 250GB allowance, it may be some time before most customers find themselves routinely having to limit their usage to avoid exceeding it.  But that assumes Comcast doesn’t follow some other providers into a limbo dance of lowered usage allowances.  With a meter in place, it’s as simple as lowering the cap and telling the customer to check before they use.

What do Comcast customers think?  Comcast’s blog amusingly illustrates some company employees love it, and most consumers hate it:

“Finally! This is great stuff, I cannot wait for this to roll out in our market. We’ve been waiting and customers have been asking for months. Keep up the good work out there, and let’s never stop being innovative. We ROCK!” — Ozzie Navarro, presumably the ‘we’ is this instance refers to an author employed by Comcast.

“How is it great that you’re capping a service I pay monthly for at great expense? Now I can see it in a meter, wow! Upgrade your damn infrastructure to support more bandwidth instead of cutting off customers.” — Jason

“Don’t think you are fooling people by saying, ‘Only x% of people use over 250gb/month, and 1-x% of people won’t have to worry.’ Would you outright deny that you are implementing this feature because you feel your TV industry is threatened by Netflix, Slingbox, Hulu.com, et al.? You say it is to provide all users with a better experience. You say that because some people are “hogging the internet”, grandma can’t look at photos of her grandchildren fast enough. Did it ever occur to you that more people are using more web-intensive programs everyday? It’s not like bandwidth is a finite resource. As much as you guys want to say it is, bandwidth is only limited by ISPs. You love to say that your “networks are overburdened.” Hate to point out the obvious, but you are the ones selling the service so you should plan accordingly for usage. You sell people an advertised rate of 10Mbps, knowing full well that unless everyone else in their neighborhood is offline, there isn’t a snowball’s chance in hell you’ll get these speeds.

Then you have the nerve to say because so many people are “abusing their privilege” you must implement a bandwidth cap to “maintain the integrity of our networks.” I pay $50/month just to access this wonderful series of tubes known as the internet. When I was sold this plan, I was told very specifically that it was UNLIMITED.  That meant, if I maxed out my possible internet consumption everyday — no big deal — that’s what unlimited means. It’s becoming more and more obvious that this whole thing is a money grab, much like overdraft fees from our favorite financial institutions. I love how in the last comment you preach about rolling out your DOCSIS 3.0 system, which will supposedly let people have higher speeds. You don’t plan on upgrading the amount we can use per month though do you? That was suspiciously left absent from your article. Basically you are giving us the power use the internet in more innovative ways, but punishing us for trying to take advantage of your speeds. Thanks for giving me the ability to hit the upper limit more easily and quickly!” — Matt

“So a service whose advertising mentions NOTHING about data caps is actually capped, eh? That’s nice. It’s also really nice that you’re rolling out a faster product, so people can use up their allotted internet EVEN FASTER. Comcast doesn’t want people not paying for their ridiculously overpriced TV service, so they cripple their internet so you don’t have a choice. Really nice.” — Comcast customer

The Internet Overcharging Express: We Derail One Limited Service Logic Train-Wreck, They Railroad Us With Another

Phillip "He Who Shall Not Be Named" Dampier

Phillip "He Who Shall Not Be Named" Dampier

I’ve tangled with Todd Spangler, a columnist at cable industry trade magazine Multichannel News before.  This morning, I noticed Todd suddenly added me to the list of people he follows on Twitter.  Now I see why.

Todd is back with another one of his cheerleading sessions for Internet Overcharging schemes, promoting consumption-based billing schemes as inevitable, backed up by his industry friends who subscribe and help pay his salary and a guy from a company whose bread is buttered selling the equipment to “manage” the Money Party.

GigaOm’s Stacey Higginbotham and Broadband Reports’ Karl Bode don’t pay his salary, so it’s no surprise he disagrees them.  Oh, and I’m in the mix as well, but not by name.  Amusingly, I’m “the StoptheCap! guy, who’s making a career directing his bloggravation at The Man.”

Todd doesn’t consider himself “an edgy blogger type because, as everyone knows, I am The Man,” he writes.

Actually, Todd, you are Big Telecom’s Man, paid by an industry trade magazine to write industry-friendly cozy warm and fuzzies that don’t rock the boat too much and threaten those yearly subscription fees, as well as your paid position there.  I’ve yet to read a trade publication that succeeds by disagreeing with industry positions, and I still haven’t after today.

Unlike Todd, I am not paid one cent to write any of what appears here.  This site is entirely consumer-oriented and financed with no telecom industry involvement, no careers to make or break, and this fight is not about me.  I’m just a paying customer like most of our readers.

This site is about good players in the broadband industry who deserve to make good profits and enjoy success providing an important service to subscribers at a fair price, and about those bad players who increasingly seek to further monetize their broadband offerings by charging consumers more for the same service.  As one of the few telecom products nearly immune from the economic downturn, some providers are willing to leverage their barely-competitive marketplace position to cash in.

It’s about who has control over our broadband future – certain corporate entities and individuals who openly admit their desire to act as a controlling gatekeeper, or consumers who pay for the service.  It’s also about organizing consumers to push back when industry propaganda predominates in discussions about broadband issues, and we know where we can find plenty of that.  Finally it’s about evangelizing broadband, not in a religious sense, but promoting its availability even if it means finding alternatives to private providers who leave parts of urban and rural America unserved because it just doesn’t produce enough profit.

Let’s derail Todd’s latest choo-choo arguments.

“The idea of charging broadband customers based on what they use is still in play.” — That’s never been in play.  True consumption billing would mean consumers pay exactly for what they use.  If a consumer doesn’t turn on their computer that month, there would be no charge.  That’s not what is on offer.  Instead, providers want to overcharge consumers with speed –and– usage-based tiers that, in the case of Time Warner Cable, were priced enormously higher than current flat-rate plans.  Customers would be threatened with overlimit fees and penalties for exceeding a paltry tier proposed by the company last April.  The ‘Stop the Cap! guy’ didn’t generate thousands of calls and involvement by a congressman and United States senator writing blog entries.  Impacted consumers instinctively recognized a Money Party when they saw one, and drove the company back.  A certain someone at Multichannel News said Time Warner Cable was “taking one for the team.”  At least then you were open about whose side you were on.

“Verizon just wants to make more money by charging more for the same service. What an outrage! It’s not like the company spent billions and billions to build out their network and needs to recoup that investment.” — Recouping an investment is easily accomplished by providing customers with an attractive, competitively priced service that delivers better speed and more reliability than the competition.  Provide that in an era when fiber optic technology and bandwidth costs are declining, and not only does the phone company survive the coming copper-wire obsolescence, it also benefits from the positive press opinion leaders who clamor for your service will generate to attract even more business.  Stacey’s comments acknowledged the positive vibes consumers have towards Verizon’s fiber investment — positive vibes they are now willing to throw away.

Verizon FiOS already gets to recoup its investment from premium-priced speed tiers that are favored by those heavy broadband users.  Most will happily hand over the money and stay loyal, right up until you ask for too much.  Theoretically charging your best customers $140 a month for 50Mbps/20Mbps service and then limiting it to, say, 250GB of usage will be an example of asking for too much.  Verizon didn’t get into the fiber optics business believing their path to return on investment was through consumption billing for broadband.

“Today’s broadband networks — not even FiOS — are not constructed to deliver peak theoretical demand and adding more capacity to the home or farther upstream will require investment.” — Readers, today’s newest excuse for overcharging you for your broadband access is “peak theoretical demand.”  It used to be peer-to-peer, then online videos, and now this variation on the “exaflood” nonsense.  It sounds like Todd has been reading some vendor’s press release about network management.  Peak theoretical demand has never been the model by which residential broadband networks have been constructed.  The Bell System constructed a phone network that could withstand enormous call volumes during holidays or other occasional events.  Broadband networks were designed for “best effort” broadband.  If we’d been living under this the peak demand broadband model, cable modem service and middle mile DSL networks wouldn’t be constructed to force hundreds of households to share one fixed rate connection back to the provider.  It’s this design that causes those peak usage slowdowns on overloaded networks that work fine at other times.

No residential broadband provider is building or proposing constructing peak theoretical demand networks that are good enough to include a service and speed guarantee.  Instead, cable providers are moving to affordable DOCSIS 3 upgrades, which continue the “shared model” cable modems have always relied on, except the pipeline we all share can be exponentially larger and deliver faster speeds.  Will this model work for decades to come?  Perhaps not, but it’s generally the same principle Time Warner Cable is using to deliver HD channels quietly ‘on demand’ to video customers without completely upgrading their facilities.  You don’t hear them talk about consumption billing for viewing, yet similar network models are in place for both.

“Is it fairer to recover that necessary investment in additional capacity from the heaviest users, who are driving the most demand?” Apparently so, because providers already do that by charging premium pricing for faster service tiers attractive to the heaviest users.  But Todd, as usual, ignores the publicly-available financial reports which tell a very different tale – one where profits run in the billions of dollars for broadband service, where many providers Todd feels urgently need to upgrade their networks are, in reality, spending a lower percentage on their network infrastructure costs, all at the same time bandwidth costs are either dropping or fixed, making it largely irrelevant how much any particular user consumes. What matters is how much of a percentage of profits providers are willing to put back into their networks.

Do people like Todd really believe consumers aren’t capable of reading financial reports and watching executives speak with investors about the fact their networks are well-able to handle traffic growth (Glenn Britt, Time Warner Cable CEO), that consumption based billing represents potential increased revenue for companies that deny they even have a traffic management problem (Verizon), or that broadband is like a drug that company officials want to encourage consumers to keep using without unfriendly usage caps, limits, or consumption billing (Cablevision.)

“From 7 to 10 p.m., we’re all consumption kings,” Sandvine CEO David Caputo told Todd. “Bandwidth caps don’t do anything for you.” The implication of this finding is that “the Internet is really becoming like the electrical grid in the sense that it’s only peak that matters,” he added. — I would have been asking Todd to pick me up off the floor had Caputo said anything different.  His bread and butter, just like Todd’s, is based on pushing his business agenda.  Sandvine happens to be selling “network management” equipment that can throttle traffic, perhaps an endangered business should Net Neutrality become law in the United States.  His business depends on selling providers on the idea that sloppy usage caps don’t solve the problem — his equipment will.  Todd has no problem swallowing that argument because it helps him make his.  The rest of us who don’t work for a trade publication or a net throttler know otherwise.

What would actually be fair to consumers is to take some of those enormous profits and plow them back into the business to maintain, expand, and enhance services that deliver the gravy train of healthy revenue.  In fact, by providing even higher levels of service, they can rake in even larger profits.  You have to spend money to earn money, though.

Technology doesn’t sit still, which is why provider arguments about increased traffic leading to increased costs don’t quite ring true when financial reports to shareholders say exactly the opposite.  That’s because network engineers get access to new, faster, better networking technology, often at dramatically lower prices than what they paid for less-able technology just a few years earlier.  With new customers on the way, particularly for the cable industry picking up those dropping ADSL service from the phone company, there’s even more revenue to be had.

Or, do you think spreading the cost across all subscribers, thereby raising the flat-rate pricing for everyone, is the better option? Note that Comcast did this to an extent when it raised the monthly lease fee for cable modems by $2 (to $5), citing costs associated with its DOCSIS 3.0 buildout.

The industry already thinks so.  As we’ve documented, cable broadband providers like Time Warner Cable and Comcast (and Charter next year), are already raising prices across the board for broadband customers in many areas.  Does that mean the talk about Internet Overcharging schemes can be laid to rest?  Of course not.  They want their rate increases -and- consumption based billing for even fatter profits.

If, on the other hand, you want to pretend that all-you-can-eat plans are sustainable at today’s price tiers, you’d be kind of clueless.

Every ISP maintains an Acceptable Use Policy that provides appropriate sanctions for those users who are so far out of the consumption mainstream, they cannot even see the rest of us.  Slapping consumption based billing on consumers with steep overlimit fees and penalties punishes everyone, and the provider keeps the proceeds, and not necessarily for network upgrades.

If Todd believes consumers will sit still for profiteering by changing a model that has handsomely rewarded providers at today’s prices, with plenty of room to spare for appropriate upgrades, he’ll be the clueless one.  The cable industry’s ability to overreach never ceases to amaze me.  Every 15 years or so, legislative relief has to put them back in their place.  It’s what happens when just a handful of providers decide it is easier to hop on board the Internet Overcharging Express and cash those subscriber checks than actually engage in all-out competitive warfare with one another – keeping prices in check and onerous overcharges out of the picture.

Nobody needs to know my name to understand this.  But some of his provider friends already know the names of our readers, because PR disasters do not happen in a vacuum.  They are also acquainted with two other names: Rep. Eric Massa and Sen. Charles Schumer.  If they want to go hog wild with Internet Overcharging schemes, that list of names will get much, much longer.

Time Warner Cable CEO Reports Basic Cable Suffers While Broadband Gains, Still Thinks ‘Usage Based Pricing’ is the Future

Phillip Dampier November 10, 2009 Data Caps, Video 12 Comments

brittDespite challenging economic conditions, Time Warner Cable CEO Glenn Britt told CNBC broadband from the cable operator has remained strong during the downturn.  The company reported the addition of 117,000 new Road Runner customers during the third quarter, many switching from rival telephone company-provided DSL service.

A CNBC anchor who visited a conference recently and absorbed cable industry talking points about consumption-based pricing asked Britt about whether Time Warner Cable’s network had the capacity to handle skyrocketing data consumption.

“Our physical plant is very capable and we invest in it in a steady way, so I think we’re able to keep up with demand.  I think the other question you’re really raising is who pays […] is an evolving thing.  Also the history has been everybody pays the same for unlimited access.  I suspect that will change going forward to some more usage based model, but that in itself is controversial so we’ll have to see what happens,” Britt said.

Britt’s comments about investments in their network are challenged by the company’s own financial reports which showed a decline in those investments and in the cost of obtaining network bandwidth.

Still, Time Warner Cable is upgrading some areas to DOCSIS 3 technology to market higher speed service to broadband enthusiasts.

The company continues to face significant challenges in its mainstay cable television business, losing 84,000 cable televison package customers in the last quarter, a result of the loss of home ownership during the economic crisis according to Britt, and a general downturn in the economy.  Still, through a combination of price increases and marketing bundled services, the company grew average revenue per subscriber to $102.48 a month in the third quarter.

Alarmism In The Media: Flu Outbreak Could Crash Internet, Unless Provider-Suggested Throttles and Rationing Are Authorized

America's Broadband Emergency Plan Allows Up to Three Cat-Chasing-Laser-Pointer videos per day

America's Broadband Emergency Plan Allows Up to Three Cat-Chasing-Laser-Pointer videos per day

The mainstream media loves a scare story.  Suggestions that a national H1N1 pandemic could bring the Internet as we know it to its knees is a surefire way to get plenty of attention.

The Chicago Tribune, among others, reports that a nationwide outbreak of virus forcing 40% of American workers to remain housebound could result in too many people sitting at home watching Hulu, bringing the entire Internet to a screeching halt.

The answer? Shut down video streaming sites and throttle users during national emergencies.

Of course, even more interesting is what never turns up in these kinds of stories — the news behind the sensationalist headlines.

The report on which this story is based comes courtesy of the General Accounting Office.  The GAO doesn’t simply issue reports willy-nilly.  A member or members of Congress specifically request the government office to research and report back on the issues that concern them.  In this instance, the report comes at the request of:

  • Rep. Henry Waxman
  • Rep. John D. Dingell
  • Rep. Joe Barton
  • Rep. Barney Frank
  • Rep. Bennie G. Thompson
  • Rep. Rick Boucher
  • Rep. Cliff Stearns
  • Rep. Edward J. Markey

The congressmen weren’t worrying exclusively about your broadband interests.  The GAO notes the study came from concern that such a pandemic could impact the financial services sector (the people that brought you the near-Depression of 2008-09).  The Wall Street crowd could be left without broadband while recovering from flu, and that simply wouldn’t do.

“Concerns exist that a more severe pandemic outbreak than 2009’s could cause large numbers of people staying home to increase their Internet use and overwhelm Internet providers’ network capacities. Such network congestion could prevent staff from broker-dealers and other securities market participants from teleworking during a pandemic. The Department of Homeland Security (DHS) is responsible for ensuring that critical telecommunications infrastructure is protected. GAO was asked to examine a pandemic’s impact on Internet congestion and what actions can be and are being taken to address it, the adequacy of securities market organizations’ pandemic plans, and the Securities and Exchange Commission’s (SEC) oversight of these efforts,” the report states.

Putting aside my personal desire that a little less broadband for deal-making, bailout-demanding “kings of the world” might not be a bad idea, the GAO’s report concludes what we already know — the business model of residential broadband is based on sharing connections and when too many people stay home and use them, it’s slow and doesn’t work well.

Providers do not build networks to handle 100 percent of the total traffic that could be generated because users are neither active on the network all at the same time, nor are they sending maximum traffic at all times. Instead, providers use statistical models based upon past users’ patterns and projected growth to estimate the likely peak load of traffic that could occur and then design and build networks based on the results of the statistical model to accommodate at least this level. According to one provider, this engineering method serves to optimize available capacity for all users. For example, under a cable architecture, 200 to 500 individual cable modems may be connected to a provider’s CMTS, depending on average usage in an area. Although each of these individual modems may be capable of receiving up to 7 or 8 megabits per second (Mbps) of incoming information, the CMTS can transmit a maximum of only about 38 Mbps. Providers’ staff told us that building the residential parts of networks to be capable of handling 100 percent of the traffic that all users could potentially generate would be prohibitively expensive.

In other words, guess your customer demand correctly and 200-500 homes can all share one 38Mbps connection.  Guess incorrectly, or put off expanding that network to meet the anticipated demands because your company wants to collect “cost savings” from reduced investment, and everyone’s connection slows down, especially at peak times.

One way to dramatically boost capacity for cable operators is to bond multiple channels of broadband service together, using the latest DOCSIS 3 standard.  It provides cable operators with increased flexibility to meet growing demands on their network without spending top dollar on wholesale infrastructure upgrades.  Many operators are already reaping the rewards this upgrade provides, by charging customers higher prices for higher speed service.  But it also makes network management easier without inconveniencing existing customers with slowdowns during peak usage.

The GAO didn’t need 77 pages to produce a report that concludes broadband usage skyrockets when people are at home.  Just watching holiday shopping traffic online spike during deal days like “Cyber Monday,” after Thanksgiving would illustrate that.  Should 40 percent of Americans stay home from work, instead of browsing the Internet from their work machines, they’ll be doing it from home.  That moves the bottleneck from commercial broadband accounts to residential broadband networks.

The GAO says such congestion could create all sorts of problems for the financial services sector, slowing down their broadband access.

Providers’ options for addressing expected pandemic-related Internet congestion include providing extra capacity, using network management controls, installing direct lines to organizations, temporarily reducing the maximum transmission rate, and shutting down some Internet sites. Each of these methods is limited either by technical difficulties or questions of authority. In the normal course of business, providers attempt to address congestion in particular neighborhoods by building out additional infrastructure—for example, by adding new or expanding lines and cables. Internet provider staff told us that providers determine how much to invest in expanding network infrastructure based on business expectations. If they determine that a demand for increased capacity exists that can profitably be met, they may choose to invest to increase network capacity in large increments using a variety of methods such as replacing old equipment and increasing the number of devices serving particular neighborhoods. Providers will not attempt to increase network capacity to meet the increased demand resulting from a pandemic, as no one knows when a pandemic outbreak is likely to occur or which neighborhoods would experience congestion. Staff at Internet providers whom we interviewed said they monitor capacity usage constantly and try to run their networks between 40 and 80 percent capacity at peak hours. They added that in the normal course of business, their companies begin the process to expand capacity when a certain utilization threshold is reached, generally 70 to 80 percent of full capacity over a sustained period of time at peak hours.

However, during a pandemic, providers are not likely to be able to address congestion by physically expanding capacity in residential neighborhoods for several reasons. First, building out infrastructure can be very costly and takes time to complete. For example, one provider we spoke with said that it had spent billions of dollars building out infrastructure across the nation over time, and adding capacity to large areas quickly is likely not possible. Second, another provider told us that increasing network capacity requires the physical presence of technicians and advance planning, including preordering the necessary equipment from suppliers or manufacturers. The process can take anywhere from 6 to 8 weeks from the time the order is placed to actual installation. According to this provider, a major constraint to increasing capacity is the number of technicians the firm has available to install the equipment. In addition to the cost and time associated with expanding capacity, during a pandemic outbreak providers may also experience high absenteeism due to staff illnesses, and thus might not have enough staff to upgrade network capacities. Providers said they would, out of necessity, refrain from provisioning new residential services if their staff were reduced significantly during a pandemic. Instead, they would focus on ensuring services for the federal government priority communication programs and performing network management techniques to re-route traffic around congested areas in regional networks or the national backbone. However, these activities would likely not relieve congestion in the residential Internet access networks.

It’s clear some broadband providers are not willing to change their business models to redefine congestion from measurements taken during peak usage when speeds slow, to those that anticipate and tolerate traffic spikes.  That means making due with what broadband providers are delivering today and developing technical and legal means to ration, traffic shape, or simply cut access to high bandwidth traffic during ‘appropriate emergencies.’  Right on cue, the high bandwidth barrage of self-serving provider talking points are on display in the report:

Providers identified one technically feasible alternative that has the potential to reduce Internet congestion during a pandemic, but raised concerns that it could violate customer service agreements and thus would require a directive from the government to implement. Although providers cannot identify users at the computer level to manage traffic from that point, two providers stated that if the residential Internet access network in a particular neighborhood was experiencing congestion, a provider could attempt to reduce congestion by reducing the amount of traffic that each user could send to and receive from his or her network. Such a reduction would require adjusting the configuration file within each customer’s modem to temporarily reduce the maximum transmission speed that that modem was capable of performing—for example, by reducing its incoming capability from 7 Mbps to 1 Mbps. However, according to providers we spoke with, such reductions could violate the agreed-upon levels of services for which customers have paid. Therefore, under current agreements, two providers indicated they would need a directive from the government to take such actions.

Shutting down specific Internet sites would also reduce congestion, although many we spoke with expressed concerns about the feasibility of such an approach. Overall Internet congestion could be reduced if Web sites that accounted for significant amounts of traffic—such as those with video streaming—were shut down during a pandemic. According to one recently issued study, the number of adults who watch videos on video-sharing sites has nearly doubled since 2006, far outpacing the growth of many other Internet activities. However, most providers’ staff told us that blocking users from accessing such sites, while technically possible, would be very difficult and, in their view, would not address the congestion problem and would require a directive from the government.

You have to love some of the players in the broadband industry who trot out their most-favored “network management” talking points to handle a national emergency.  It’s interesting to note providers told the GAO they were concerned with violating customer agreements regarding speed guarantees, when most providers never guarantee residential service speeds.  Their first solution is the Net Neutrality-busting traffic throttle, to slow everyone down to ration the “good enough for you” network in your neighborhood.  Shutting down too-popular, high bandwidth websites like Hulu (no worries – you can watch your favorite shows on our cable TV package) is apparently someone’s good idea, but considering providers admit it wouldn’t actually solve the congestion problem, one’s imagination can ponder what other problems such a shutdown might solve.

One provider indicated that such blocking would be difficult because determining which sites should be blocked would be a very subjective process. Additionally, this provider noted that technologically savvy site operators could change their Internet protocol addresses, allowing users to access the site regardless. Another provider told us that some of these large bandwidth sites stream critical news information. Furthermore, some state, local, and federal government offices and agencies, including DHS, currently use or have plans to increase their use of social media Web sites and to use video streaming as a means to communicate with the public. Shutting down such sites without affecting pertinent information would be a challenge for providers and could create more Internet congestion as users would repeatedly try to access these sites. According to one provider, two added complications are the potential liability resulting from lawsuits filed by businesses that lose revenue when their sites are shutdown or restricted and potential claims of anticompetitive practices, denial of free speech, or both. Some providers said that the operators of specific Internet sites could shut down their respective sites with less disruption and more effectively than Internet providers, and suggested that a better course of action would be for the government to work directly with the site operators.

A very subjective process indeed, but one many providers have sought to keep within their “network management” control as they battle Net Neutrality.  One would think “potential claims of anti-competitive practices” would represent an understatement, particularly if cable industry-operated TV Everywhere theoretically kept right on running even while Hulu could not.  As long time net users already know, outright censorship or content blockades almost always meet resistance from enterprising net users who make it their personal mission to get around such limits.

Expanding broadband networks to provide a better safety cushion during periods of peak usage is looking better and better.

Providers could help reduce the potential for a pandemic to cause Internet congestion by ongoing expansions of their networks’ capacities. Some providers are upgrading their networks by moving to higher capacity modems or fiber-to-the-home systems. For example, some cable providers are introducing a network specification that will increase the download capacity of residential networks from the 38 Mbps to about 152 to 155 Mbps. In addition to cable network upgrades, at least one telecommunications provider is offering fiber-to-the home, which is a broadband service operating over a fiber-optic communications network. Specifically, fiber-to-the-home Internet service is designed to provide Internet access with connection speeds ranging from 10 Mbps to 50 Mbps.

Hello.

Sounds like a plan to me, and not just for the benefit of the Wall Street crowd sick at home with the flu.  Such network upgrades can be economical and profitable when leveraged to upsell the broadband enthusiast to higher speed service tiers.  During periods of peak usage, such networks will withstand considerably more demand and provide a better answer to that nagging congestion problem.

The alternative is Comcast or Time Warner Cable, in association with the Department of Homeland Security, having to appear on Wolf Blitzer’s Situation Room telling Americans they have a broadband rationing plan that will give you six options of usage per day.  Choose any one:

  • Up to three videos of cats chasing laser pointers on YouTube
  • One episode of Hogan’s Heroes
  • Up to six videos of your friends playing Guitar Hero on Dailymotion
  • Unlimited access to Drugstore.com to browse remedies
  • Five MySpace videos of your favorite bands
  • Up to 500 “tweets” boring your followers with every possible detail of your stuck-at-home-sick routine

Cable In Denial: Phooey on FiOS – Cable Industry Downplays Fiber Optics At Cable Expo

Phillip Dampier October 29, 2009 Broadband Speed, Data Caps, Video 3 Comments

It’s appropriate that it is snowing heavily in Denver as attendees of the Society of Cable Telecommunications Engineers meet at Cable-Tec Expo ’09, under the banner “Touch the Technology.”

Yesterday’s Technology Leadership Roundtable, according to Lightwave’s Steven Hardy, was reserved for out of touch Verizon fiber bashing:

The title of this morning’s Technology Leadership Roundtable was “Enough Already!” “Enough of what?” you ask. Answers the roundtable description: “Growing a little weary of all that FiOS in your face?” The short answer, not surprisingly, is yes. Roundtable moderator Leslie Ellis (Ellis Edits LLC) opened the discussion by asking whether the cable-TV community should be defensive about the fact that it hasn’t fully embraced FTTH — particularly since the industry invented video over fiber and carries more video over fiber than anyone else.

Much pooh-poohing of FTTH and telcos ensued. Paul Liao, president and CEO of CableLabs, said that the MSOs are the big dogs when it comes to video and becoming big dogs in voice delivery — and when you’re a big dog, you’re going to attract competitive attention.

Dermot O’Carroll, SVP, engineering and network operations, at Rogers Cable Communications up in Canada, asserted that fiber “doesn’t do much” for voice or video (I assume he meant fiber access versus HFC) and perhaps only a little bit when it comes to Internet access. This last shortfall should go away with deployment of DOCSIS 3.0, he said.

Liao agreed that DOCSIS 3.0-enabled HFC should prove more than adequate for customer needs today and into the future, adding that DOCSIS 3.0 should enable more bandwidth than anyone will ever need. (This sounds like one of those “eat your words in 10 years or less” statements, but Liao is certainly smarter than I am and more versed in DOCSIS 3.0 capabilities.)

Meanwhile, at least two workshops later in the week will discuss how to migrate HFC networks to FTTH. It doesn’t hurt to hedge your bets, apparently. Getting a better understanding of how MSOs really feel about FTTH is one of my goals here.

The cable industry has routinely confronted the threat of fiber optics by dismissing it as irrelevant wizardry until they are forced to upgrade their networks to try and match the capabilities a well run fiber to the home system can provide.  Broadband service with equal upload and download speeds on cable?  Not so much.  The sheer bandwidth potential of fiber optics?  Quite nice, thank you.  The potential for Verizon FiOS to be positioned to meet the current and future needs of customers without a lot of expensive upgrades?  Very high, assuming it’s priced competitively.


Fiber bashing snowjob from Time Warner Cable

Rogers Cable has a point when they dismiss fiber’s potential for broadband.  That’s because the company treats its customers to a host of Internet Overcharging schemes which provide blazing fast speeds that customers can’t use for very long without facing overlimit charges on next month’s bill.  Few companies want to provide robust video broadband service in a country where such usage limits and other schemes prevail from Vancouver to St. John’s.
