Despite assurances from FCC Chairman Ajit Pai that the repeal of net neutrality would inspire cable operators to increase investment in broadband, a year-long virtual spending freeze by the nation’s top cable operators has resulted in a major vendor pulling out of the next generation cable broadband standard until there are signs cable companies are prepared to spend money on upgrades again.

Cisco Systems has confirmed to Light Reading it has ceased investment in Full Duplex DOCSIS technology that would allow cable customers to get the same upload speed as download speed.

“Cisco has internally communicated that we are suspending further investment in Full Duplex DOCSIS (FDX) until the market timing, ecosystem development and size of the opportunity can be quantified,” a Cisco spokesperson said in a statement to Light Reading.

The news is a significant blow to the cable industry’s plans to upgrade to 10 Gbps capacity and a growing desire by customers to get much faster upload speeds than are currently available.

Cisco blamed its pullback on the cable industry’s lack of investment in broadband upgrades and an uncertain timetable when major cable companies including Comcast, Charter, Cox, and others will announce specific plans for future upgrades.

FDX has already been the victim of delays. Originally planned as an incremental upgrade for DOCSIS 3.1, FDX is now scheduled to be included in CableLabs’ DOCSIS 4.0 specification, which is not expected to be released for a few years. FDX will be one of several new features incorporated into the next cable broadband standard, which will allow for low latency connections and an expanded amount of coaxial cable spectrum that can be devoted to broadband services.

The cable industry has been taking a sober look at the costs associated with adopting FDX, which includes scrapping a significant amount of coaxial cable and pushing fiber optic technology much closer to customers. Cable systems that want to move towards FDX will have to remove amplifiers that maintain signal strength between the fiber optic connection and the coaxial cable entering customers’ homes. In some cases, this will mean removing multiple amps from the cable system and stringing new fiber optic cables deep into neighborhoods. This is known as node+0 architecture. Moving towards node+0 is expected to be both costly and labor intensive, and some large cable systems and investors are balking.

“There are a lot of operators who have no intention of getting to a node+0 environment in next 10 years,” Tom Cloonan, chief technical officer of Arris’ Networks Solutions unit, told Multichannel News last fall. “It’s going to take a while to run fiber deep enough to get to node+0.”

To date, the only major cable operator that has definitively backed moving to node+0 is Comcast. Other cable companies, notably Cox Communications, are seeking a much cheaper solution to manage upgrades.

Extended Spectrum DOCSIS (ESD)

An emerging alternative concept has emerged that can be implemented at a lower cost. Extended Spectrum DOCSIS (ESD) would essentially repurpose much of the bandwidth available over a coaxial cable solely to broadband service. DOCSIS 3.1 currently dedicates 1.2 GHz of spectrum for broadband. FDX would increase that to more than 1.8 GHz. ESD would devote as much as 3 (or possibly 6) GHz of spectrum for data transmissions. The cable system would devote as much as half of that spectrum for downstream traffic, the other half for upstream. Theoretical speeds in the future could be as high as 60 Gbps, and ESD will not require cable systems to ditch existing amplifiers. It will, however, force some cable systems to evaluate and replace at least part of their older coaxial cable network. ESD will be less forgiving of deteriorating cable than DOCSIS 3.1 is.

Unfortunately for Cisco, and other cable broadband equipment suppliers, ESD is still more theory than fact, and with cable operators demonstrating they are in no rush to move to either FDX or ESD, it will likely be several years before either technology becomes available to customers. Cloonan predicts ESD will not be implemented by cable systems until the mid-2020s.

The muddy waters over where the cable industry will ultimately plant the flag on next generation broadband upgrades means a lot of uncertainty for companies like Cisco, which has resulted in the company pulling out of developing FDX until there are assurances the cable industry has a timetable to implement it. The decision has also cost several Cisco employees their jobs. Multiple industry sources told Light Reading job cuts included 5-7 engineers dedicated to FDX, and some sources also report at least 40 employees in the cable access division of Cisco have also been let go.

If certainty does not return to the cable broadband market soon, Cisco could ultimately jettison much of its cable broadband technology division to focus on other technology growth areas.

The cable industry’s investment freeze is ironic because the Trump Administration’s FCC trumpeted its decision to repeal net neutrality, claiming it would inspire cable operators to accelerate investment in network upgrades. It appears the exact opposite has occurred.

The median bandwidth use slowdown (Image: BTIG Research)

Despite perpetual cries of Internet brownouts, usage blowouts, and data tsunamis that threaten to overwhelm the Internet, new data shows broadband usage has leveled off in North America, undercutting providers’ favorite excuse for usage limits and consumption billing.

Sandvine today released its latest broadband usage study, issued twice yearly. The results show a clear and dramatic decline in usage growth in North America, with median usage up just 5% compared to the same time last year. That is a marked departure from the 190% and 77% growth measured in two earlier periods. In fact, as Richard Greenfield from BTIG Research noted, mean bandwidth use was down 13% year-over-year, after the second straight six month period of sequential decline.

Companies like Cisco earn millions annually pitching network management tools to providers implementing usage caps and consumption billing. For years, the company has warned of Internet usage floods that threaten to make the Internet useless (unless providers take Cisco’s advice and buy their products and services).

“Demand for Internet services continues to build,” said Roland Klemann from Cisco’s Internet Business Solutions Group. “The increasing popularity of smartphones, tablets, and video services is creating a ‘data tsunami’ that threatens to overwhelm service providers’ networks.”

Providers typically use “fairness” propaganda when introducing “usage based pricing,” blaming exponential increases in broadband usage and costly upgrades “light users” are forced to underwrite. A leveling off in broadband usage undercuts that argument.

A Cisco White Paper intended for the eyes of Internet Service Providers further strips the façade off the false-“fairness” argument, exposing the fact usage pricing has little to do with traffic growth, pricing fairness, or the cost of upgrades:

In 2011, broadband services became mainstream in developed countries, with fixed-broadband penetration exceeding 60 percent of households and mobile broadband penetration reaching more than 40 percent of the population in two-thirds of Organisation for Economic Co-operation and Development (OECD) countries.

Meanwhile, traditional voice and messaging revenues have strongly declined due to commoditization, and this trend is expected to continue. Therefore, operators are now relegated to connectivity products. The value that operators once derived from providing value-added services is migrating to players that deliver services, applications, and content over their network pipes.

As if this were not enough, Internet access prices are dropping, sales volumes are declining, and markets are shrinking. The culprit: flat rate “all-you-can-eat” pricing. Such a model lacks stability—sending service provider pricing into a downward spiral—because it ignores growth potential and shifts the competition’s focus from quality and service differentiation to price.

While Klemann was spouting warnings about the dire implications of a data tsunami, Cisco’s White Paper quietly told providers what they already know:

Maximum Profits

“[Wired] broadband operators should be able to sustain forecasted traffic growth over the next few years with no negative impact on margins, as the incremental capital expenses required to support it are under control.”

If usage limits and consumption billing are not required to manage data growth or cover the cost of equipment upgrades, why adopt this pricing? The potential to exploit more revenue from mature broadband markets that lack robust competition.

“In light of the forecasted Internet traffic growth mentioned earlier and competitiveness in the telecommunications market, Cisco believes that fixed-line operators should consider gradually introducing selected monthly traffic tiers to sustain [revenue], while a) signaling to customers that “traffic is not free,” and b) monetizing bandwidth hogs more sustainably.”

Cisco makes its recommendation despite knowing full well from its own research that customers hate usage-based pricing.

“The introduction of traffic tiers and caps—especially for fixed broadband services—is not welcomed by the majority of customers, as they have learned to ‘love’ flat rate all-you-can-eat pricing. Most customers consider usage-based pricing for broadband services ‘unfair,’ according to the 2011 Cisco IBSG Connected Life Market Watch study.”

Cisco teaches providers how to price broadband like trendy boutique bottled water and blame it on growing Internet usage.

But with competition lacking, Cisco’s advice is to move forward anyway, as long as providers initially introduce caps and consumption billing at prices that do not impact the majority of customers… at first. In uncompetitive markets, Cisco predicts customers will eventually pay more, boosting provider revenue. Cisco’s “illustrative example” of usage billing in practice set prices at $45 a month for up to 50GB of usage, $60 a month for 50-100GB, $75 for 100-150GB, and $150 a month for unlimited access — more than double what customers typically pay today for flat rate access.

Usage billing arrives right on time to effectively handle online video, which increasingly threatens revenue from cable television packages.

Sandvine’s new traffic measurement report notes the increasing prominence of online video services like Netflix, YouTube, Hulu, and Amazon Video.

“As with previous reports, Real-Time Entertainment (comprised of streaming video and audio) continues to be the largest traffic category on virtually every network we examined, and we expect its continued growth to lead to the emergence of longer form video on mobile networks globally in to 2014,” Sandvine’s report noted.

Sandvine found that over half of all North American Internet traffic during peak usage periods comes from two services: Netflix and YouTube. YouTube globally is the leading source of Internet traffic in the world, according to Sandvine.

An old excuse for usage caps on “data hogs” – peer-to-peer file-sharing, continues its rapid decline towards irrelevance, now accounting for less than 10 percent of total daily traffic in North America. A decade earlier, file swapping represented 60 percent of Internet traffic.

Cisco’s answer for the evolving world of popular online applications is a further shift in broadband pricing towards “value-based tiers” that monetize different online applications by charging broadband users extra when using them. Cisco is promoting an idea that well-enforced Net Neutrality rules would prohibit.

Citing the bottled water market, Cisco argues if some customers are willing to pay up to $6 for a liter of trendy Voss bottled water, flat rate “one price fits all” broadband is leaving a lot of money on the table. With the right marketing campaign and a barely competitive marketplace, providers can charge far higher prices to get access to the most popular Internet applications.

“Research from British regulator Ofcom shows that consumers are becoming ‘addicted’ to broadband services, and heavy broadband users are willing to pay more for improved broadband service options.”

Wharton School professors Jagmohan Raju and John Zhang concluded price is the single most important lever to drive profitability.

The political implications of blaming phantom Internet growth and manageable upgrade costs for the implementation of usage caps or usage-based billing is uncertain. Even the “data hog” meme providers have used for years to justify usage caps is now open to scrutiny. Sandvine found the top 1% of broadband users primarily impact upstream resources, where they account for 39.8% of total upload traffic. But the top 1% only account for 10.1% of downstream traffic. In fact, Apple is likely to provoke an even larger, albeit shorter-term impact on a provider’s network from software upgrades. When the company released iOS7, Apple Updates immediately became almost 20% of total network traffic, and continued to stay above 15% of total traffic into the evening peak hours, according to Sandvine.

Some other highlights:

• Average monthly mobile usage in Asia-Pacific now exceeds 1 gigabyte, driven by video, which accounts for 50% of peak downstream traffic. This is more than double the 443 megabyte monthly average in North America.
• In Europe, Netflix, less than two years since launch, now accounts for over 20% of downstream traffic on certain fixed networks in the British Isles. It took almost four years for Netflix to achieve 20% of data traffic in the United States.
• Instagram and Dropbox are now top-ranked applications in mobile networks in many regions across the globe. Instagram, due to the recent addition of video, is now in Latin America the 7th top ranked downstream application on the mobile network, making it a prime candidate for inclusion in tiered data plans which are popular in the region.
• Netflix (31.6%) holds its ground as the leading downstream application in North America and together with YouTube (18.6%) accounts for over 50% of downstream traffic on fixed networks.
• P2P Filesharing now accounts for less than 10% of total daily traffic in North America. Five years ago it accounted for over 31%.
• Video accounts for less than 6% of traffic in mobile networks in Africa, but is expected to grow faster than in any other region before it.

Cisco has released the results of the third annual study from the Saïd Business School at Oxford University, which looks at broadband quality in 72 countries and 239 cities around the world.  The results are an embarrassment to much of North America’s broadband.

Using data from 40 million real-life broadband quality tests conducted in May-June of 2010 on the Internet speed testing site, Speedtest.net, the researchers were able to generally evaluate broadband conditions in the 72 countries which generated enough tests to provide useful results.

Although these kinds of studies often end up indirectly promoting Cisco’s own products (which they’d argue go hand-in-hand with broadband improvement), the findings highlight the very real problem that most aggressive broadband development is taking place outside of North America.  Here at home, reduced investment and foot-dragging has kept growth in check, even as prices continue to rise.

Based on the findings, the countries with the most sophisticated and advanced broadband networks are:

While the United States and Canada both languish in 15th place, broadband in South Korea has gone from excellent to outstanding as it continues aggressive, almost revolutionary improvements in service and speed:

• South Korea tops the broadband leadership ranking for the second year in a row;
• Broadband quality in South Korea is ranked the highest and has set a new benchmark for the world;
• Average download throughput is 33.5 Mbps, an increase of 55% from 2009, average upload throughput is 17 Mbps, an increase of 430%, and average latency is 47ms, an improvement of 35% vs. 2009 figure;
• South Korea has achieved 100% broadband penetration.

Cisco’s study found North America is in peril of falling even further behind because providers are trying to incrementally upgrade inferior, obsolete copper-wire phone networks on the cheap instead of replacing them.

As long as providers in the United States and Canada maintain a Dollar Store-mentality towards broadband improvement, both countries will increasingly fall further and further behind countries many Americans couldn’t find on a map.

Developing economies, especially in eastern Europe, are poised to leapfrog over North America and potentially become new powerhouses in the digital global economy of the future.  Among the nations on the verge of blowing past the United States and Canada: Lithuania, Latvia, Bulgaria, Romania, the Czech Republic and Hungary.

Welcome to the 500GB Broadband Economy

Cisco’s study also includes some important findings about data consumption that expose North American broadband providers who support Internet Overcharging schemes as direct threats to our economic future in a knowledge economy:

The study assessed the average consumption of different household segments and found major differences between basic-digital homes and smart and connected homes:

• Basic digital homes which mainly use the web for simple-quality requirement applications such as web browsing, instant messaging and social networking, consume about 20 GB per month;
• Smart and connected households, who would use the web for high definition video communication, high definition entertainment, tele-education or telemedicine, home security and others, can easily consume 500 GB per month and require an assured bandwidth of 18 Mbps.

Under these terms, Canada’s digital economy is already destined to fail because virtually every provider in the country limits broadband consumption to levels far below that required by “smart and connected households.”  In the United States, some providers have suggested as little as 5GB would represent “enough usage” under residential broadband accounts.  The nation’s largest cable company, Comcast, limits consumption to half the amount required.  Those advocating unlimited broadband or far higher limits are accused of being “bandwidth hogs” or pirates by many of these providers and their dollar-a-holler friends.

World leaders in broadband have some things in common: availability of inexpensive, unlimited broadband delivering fiber-fast speeds.  Those falling behind or at the bottom are raising broadband prices, putting limits on consumption and delivering slow broadband speeds that would draw laughter in countries as diverse as Japan, Sweden, and the United Arab Emirates.
