Virtualizing the World of Cable
By Wayne Hickey – When cable operators saw huge demands in linear video, Video-on-Demand (VoD) and high-speed data services, and faced with an aging analog infrastructure, they moved to a Converged Cable Access Platform (CCAP) to increase capacity and throughput. CCAP combines headend functions into a single architecture by combing Edge Quadrature Amplitude Modulation (EQAM) and Cable Modem Termination System (CMTS).
Back in June 2011, CableLabs created CCAP by blending two competing platforms, a Comcast-backed Converged Multiservice Access Platform (CMAP) and a Time Warner Cable Converged Edge Services Access Router (CESAR) platform. The following year CCAP products were introduced, and deployed the year after.
Fast forward to today, cable operators are looking to implement software-based access platforms, migrate away from commonly deployed centralized, purpose-built CCAP equipment, and virtualize CCAP (vCCAP) — and thus begin the shift to a Distributed Access Architecture (DAA). Developed by CableLabs, vCCAP is the latest cable technologies that combines functions including the CMTS and EQAM.
Virtualizing and distributing MAC and PHY functions enables digital combining, eliminates analog optics with cost effective 10G Ethernet transport, and converts analog fiber nodes to digital optic IP-enabled devices. DAA makes it easier to push fiber deeper into the edge of the network, and along with the ability to support denser wavelengths for each fiber, digital optics greatly improves Carrier-to-Noise-Ratio (CNR), which will enable higher orders of QAM on the coax and higher performance DOCSIS technologies. more> https://goo.gl/EoPwPL

By Dave Lammers – It was back in 1985 that Ross Freeman invented the FPGA, gaining a fundamental patent (#4,870,302) that promised engineers the ability to use “open gates” that could be “programmed to add new functionality, adapt to changing standards or specifications, and make last-minute design changes.”
Freeman, a co-founder of Xilinx, died in 1989, too soon to see the emerging development of embedded field programmable logic arrays (eFPGAs). The IP cores offer system-on-chip (SoC) designers an ability to create hardware accelerators and to support changing algorithms. Proponents claim the approach provides advantages to artificial intelligence (AI) processors, automotive ICs, and the SoCs used in data centers, software-defined networks, 5G wireless, encryption, and other emerging applications.
With mask costs escalating rapidly, eFPGAs offer a way to customize SoCs without spinning new silicon. While eFPGAs cannot compete with custom silicon in terms of die area, the flexibility, speed, and power consumption are proving attractive.
Achronix Semiconductor (Santa Clara, Calif.) has branched out from its early base in stand-alone FPGAs, using Intel’s 22nm process, to an IP model. It is emphasizing its embeddable Speedcore eFPGAs that can be added to SoCs using TSMC’s 16FF foundry process. 7nm IP cores are under development.
Efinix Inc. (Santa Clara recently rolled out its Efinix Programmable Accelerator (EPA) technology.
Efinix (efinixinc.com) claims that its programmable arrays can either compete with established stand-alone FPGAs on performance, but at half the power, or can be added as IP cores to SoCs. The Efinix Programmable Accelerator technology can provide a look up table (LUT)-based logic cell or a routing switch, among other functions, the company said. more> https://goo.gl/nXqYvV

A Bright Idea: How LEDs Are Helping JPMorgan Chase Become Carbon Neutral
By Bruce Watson – When Mike Norton took over as managing director of real estate at JPMorgan Chase & Co. in 2015, he took on a weighty responsibility that included finding an efficient and sustainable way to oversee the branding, maintenance, upkeep and design of 6,000 branches and commercial properties around the world. It was a complex task that turned on a simple item: the light bulb.
Norton started talking to the energy management company Current, powered by GE. They devised a plan for a system focusing on improving energy efficiency, productivity and sustainability in nearly 4,500 Chase branches across the U.S. In 2016, that proposal turned into a deal for the world’s largest LED lighting installation, a project covering 25 million square feet of real estate that would eventually lead to energy savings equivalent to taking 27,000 cars off the road.
One year later, Current by GE has installed LEDs in 2,500 Chase branches. The original plan estimated that the installation would lead to 12 percent energy savings. But in reality, the savings have ranged from 15 to 50 percent, depending on the branch.
“It’s common sense: You take a 100-watt phosphorus light bulb and replace it with a 4-watt LED, and it’s going to lower energy usage by quite a bit,” Norton says. more> https://goo.gl/1UiEwV

From Light To Bright: San Diego Is Building The World’s Largest Municipal Internet Of Things
By Bruce Watson -San Diego’s newest streetlights might not look all that special — and that’s exactly the point. Designed to blend in with the rest of the city’s outdoor lighting, they’re easy to overlook. Under the surface, though, the LED fixtures are actually data-gathering machines. They will allow San Diego to build the largest municipal internet-of-things network in the world.
San Diego’s digital lighting revolution started as a modest solution to a common problem. “We were broke,” David Graham, San Diego’s deputy chief operating officer, told GE Reports in February. “In the early 2000s, we went through about a decade of fiscal crisis, and we were trying to find ways to be more efficient, save money and reduce energy usage.”
One idea to save money was to replace the yellow glow of the city’s old sodium vapor streetlamps with efficient new LED lights. In addition to providing cleaner, broader-spectrum light, the new fixtures used 60 percent less energy and slashed maintenance needs because of their longer life spans. The city replaced more than 35,000 lights, yielding an estimated $2.2 million in savings per year.
But the new fixtures also brought to light new problems. “We know when a traditional light bulb isn’t working, because it burns out,” says Austin Ashe, general manager of Current, powered by GE’s Intelligent Cities program. “But an LED doesn’t burn out. It just degrades over time.” more> https://goo.gl/6fdyFY

By Hany Farid – In 2016, Facebook, Google, Microsoft, and Twitter announced that they would work together to develop new technology to quickly identify and remove extremism-related content from their platforms. Despite some progress, serious problems remain.
First, we need a fast and effective method to remove content. Once content has been identified, reported, and determined to be illegal or in violation of terms of service, it should be immediately removed (Prime Minister Theresa May is calling for a maximum of two hours from notification to take-down).
Fourth, we need to invest in human resources. While advances in machine learning hold promise, these technologies – as technology companies will admit – are not yet nearly accurate enough to operate across the breadth and depth of the internet. There are more than a billion uploads to Facebook each day and 300 hours of video uploaded to YouTube each minute of the day.
This means that any machine-learning based solution will have to be paired with a significant team of human analysts that can resolve complex and often subtle issues of intent and meaning that are still out of reach of even the most sophisticated machine learning solutions. more> https://goo.gl/X2ACdL

Declarative Configuration when Change is Constant
By Dave McLeish – Change is a double-edged sword. To set the scene let’s first focus on recent change for the good as relates to our own domain of product lifecycle management (PLM). In the past few years, increased mobility with smart phones and tablets has provided new opportunities for mobile access to PLM. Adoption of familiar user interface (UI) patterns from everyday life (shopping cart, smart search) and enhanced possibilities for user experience through touch and virtual assistants have enabled more of the “extended enterprise” to embrace PLM. From the shop floor where there’s touch screen access to work instructions to executives empowered to simply search, sign off and interact with dashboards on their device of choice, increasingly the whole enterprise can contribute to and view the digital thread from product development to delivery.
At the heart of this change for the good is the rich web-based access to PLM that has been made possible by html5. Rich capabilities that have meant we can begin to reimagine how we collaborate and deliver products from inception, through realization and utilization. Zero-install rich, browser-based solutions remove the need for desktop install and reduce the IT deployment overhead through firewall friendly standard https requirements.
But developing in the browser has its challenges when targeting rich capabilities over high latency WAN and with limited memory resources. Arguably the greatest challenge is managing change. Whilst the emergence of HTML5 and CSS3 among other standards have provided a reliable basis for developing web solutions, the same cannot be said for much of the web development space. more> https://goo.gl/NjgcsC

By Amy Kover – Standing on a 10-foot-wide platform 365 feet above the rolling green hills of Tumbler Ridge, British Columbia, Kristen Hough looks tiny. The winds at this height are strong enough to spin a 500,000-pound wind turbine at 14 revolutions per minute. One strong gust could push a person over.
But Hough, 28, also looks unafraid. A wind technician, Hough is part of a team that is responsible for the electrical and mechanical upkeep of 61 turbines here that can produce 185 megawatts of energy — enough to power an entire city. She makes the climb to the top of a wind turbine at least once a day. At that height, Hough is in her element. “Even climbing the turbines [the first few times], it was so exciting that I knew it was what I was supposed to do,” she says.
Hough’s shift typically begins each morning at 7 a.m. when lead technician Mitch Burns assigns Hough and her five teammates to either handle routine maintenance — like tightening bolts and greasing gears — or troubleshoot problems. For instance, if the temperature in the gearbox appears a bit high, Hough needs to figure out why and fix it. Sometimes she can resolve the issue with a few taps on her laptop, but it -often requires hands-on attention instead. That’s when Hough gets out her safety gear and starts the long ascent to the top of the turbine. more> https://goo.gl/vWg2At

Optic Zoo Networks Keeps Vancouver’s Data Traveling at Blistering Speeds with Ciena
By Tony Ross – Optic Zoo Networks is a recognized brand throughout metro Vancouver due to our extensive carrier grade dark fiber network and infrastructure. Based on demand and to further accelerate our growth and better serve Tier 1 service providers, we knew it was time to take our offerings to the next level.
Our customers need to support bandwidth-hogging applications like virtual and augmented reality, as well as Internet of Things (IoT). However, in order for data to continue to flow with ease, we needed to ensure that Optic Zoo Networks was ready to support that growth. That meant offering new Carrier Ethernet Services (CES), and in turn, required that we build a Carrier Ethernet Network (CEN).
To continue to support top-echelon service providers, however, we needed to build a CEN that could scale instantaneously and meet the needs of organizations in a range of industries – from finance, healthcare, education, and more.
For example, customers that previously wanted to upgrade to higher levels of bandwidth had to go through inefficient processes, such as having to order a network loop that could take weeks. With our CEN, today’s 1G customers can easily upgrade to 10G tomorrow with a simple software upgrade. more> https://goo.gl/fh54t3
