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 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

By James Somers – “When we had electromechanical systems, we used to be able to test them exhaustively,” says Nancy Leveson, a professor of aeronautics and astronautics at the Massachusetts Institute of Technology who has been studying software safety for 35 years. She became known for her report on the Therac-25, a radiation-therapy machine that killed six patients because of a software error. “We used to be able to think through all the things it could do, all the states it could get into.
Software is different. Just by editing the text in a file somewhere, the same hunk of silicon can become an autopilot or an inventory-control system. This flexibility is software’s miracle, and its curse. Because it can be changed cheaply, software is constantly changed; and because it’s unmoored from anything physical—a program that is a thousand times more complex than another takes up the same actual space—it tends to grow without bound. “The problem,” Leveson wrote in a book, “is that we are attempting to build systems that are beyond our ability to intellectually manage.” more> https://goo.gl/XSu4jU

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 Raya Bidshahri – To contribute to human progress, it is not enough to be intelligent, resourceful, or well-connected. Those are all factors that play a significant role but aren’t the true driving forces of disruptive innovation. Stimulating positive change at civilization level also requires certain mindsets and ways of thinking.
Here are five mindsets that will allow us to leave a positive mark on humanity.
- Curiosity and Critical Thinking
One of the tragedies of our education system is that it fails to nurture the childlike sense of wonder that we are all born with.
- Intelligent Optimism
Nothing productive will come from blind optimism and ignorance of some of the brutal realities of our world.
Paving a new way forward for humanity comes at a cost. More often than not, executing a radically disruptive idea is a risk.
- Moonshot Thinking
Instead of looking to make a 10 percent gain or improvement in a current product or idea, moonshot thinking involves aiming for a 10x improvement of the status quo.
- Cosmic Perspective
We’ve all heard of “thinking big” or ‘big-picture thinking.” Moving beyond that involves having a cosmic perspective.
It’s about asking the right questions, being intelligently optimistic about the future, taking a risk with a moonshot, and maintaining a cosmic perspective. more> https://goo.gl/V2bVjb

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
