Updates from Boeing

Boeing and subsidiary Liquid Robotics team up to explore deeper possibilities for autonomous systems
BY Dan Raley – Created by Boeing subsidiary Liquid Robotics, this maritime innovation known as the Wave Glider was originally intended to record the songs of migrating whales. When integrated with Boeing’s advanced sensors for defense applications, the Wave Glider can locate undersea vehicles at substantial distances, hunt for mines, monitor land radar, and gather and relay data to other systems, all while operating on solar and wave power for months at a time.

“It’s a hidden treasure,” said Jim Bray, Boeing autonomous systems technology integrator in St. Louis. “There’s a lot going on under the sea.”

Covered with fiberglass panels and small antennas topside and tethered to a wing-like propulsion system beneath it called a sub, the Wave Glider communicates by low-Earth-orbit satellite through a command-and-control unit and surface radio modem, similarly to someone sending a text message by smartphone.

“It’s revolutionary stuff,” said Scott Willcox, Liquid Robotics technology lead. “It’s like reinventing the sail — fundamentally, it’s a new way to get around the ocean. What you can do with it is almost limitless.”

In Ventura, Calif., in July, seven months after Boeing acquired Liquid Robotics, the companies teamed to test new Wave Glider capabilities in the ocean that would be presented to a customer for the first time. The testing demonstrated how transponders placed on the ocean floor by the Wave Glider conceivably could provide an oceanic GPS. An unmanned undersea vehicle in need of updating its location could use these underwater acoustics to determine where it is and never have to surface. more>

Meet the People who brought 400G to Optical

By Helen Xenos – How big of an undertaking is involved with bringing WaveLogic Ai to market? It’s more than just moving more bits.

What does it take to introduce a new, transformational networking technology to market? How do you deliver innovation that brings tremendous value to customers one year earlier than they could access it otherwise?

You use a team that has done it before. With 40G, with 100G, with 200G, and now with 400G.

Ciena’s WaveLogic Ai, our recently available next generation coherent technology, is establishing new performance and economic benchmarks in optical networking. Operators can now double the capacity they can carry for each transponder they deploy and go longer distances without the need for regenerators.

They can offer differentiated higher capacity wavelength services and gain efficiencies in DCI and metro applications with the industry’s first single carrier 400G solution. more>

Net States Rule the World; We Need to Recognize Their Power

By Alexis Wichowski – A non-nation-state, Facebook, just topped 2 billion users—more than a quarter of the world’s population, surpassing even China’s population by almost 40 percent. In short, nation-states are not the only game in town anymore.

It is time to name this new landscape. The world is no longer dominated by nation-states alone. We have moved into a non-state, net-state era.

Why “net-states”? Because the world is no longer neatly divided into states (countries like the US, France, and India) and non-states (terrorist organizations like ISIS and al Qaeda). Ever since Barbara Ehrenreich’s 2011 article “Coming to a Theater Near You: War Without Humans” described the “emergence of a new kind of enemy, so-called non-state actors,” the term transformed into a fancy way of saying “bad guy.” Now we need new language to describe the non-state, non-bad-guys. I propose “net-states.”

Net-states are digital non-state actors, without the violence. Like nation-states, they’re a wildly diverse bunch. Some are the equivalent to global superpowers: the Googles, the Facebooks, the Twitters. Others are mere gatherings of pranksters, like Lulzsec (whose sole purpose for action is “for the lulz”—the laughs). Others still are paramilitary operations, such as GhostSec, an invite-only cyberarmy specifically created to target ISIS. There are also hacktivist collectives like Anonymous and Wikileaks. more>

Using “public interest algorithms” to tackle the problems created by social media algorithms

By Tom Wheeler – Technology and capitalism have combined to deliver us to a decidedly undemocratic outcome. The internet was once heralded as the great democratizing tool. That vision was smashed by the algorithms of the social media platforms. By fracturing society into small groups, the internet has become the antithesis of the community necessary for democratic processes to succeed.

This is bigger than the current discussion of political advertising rules for the internet. The questionable ads and postings are the result of the problem, not the cause of it. That problem is how the software algorithms that determine what you see on social media prioritize revenue over veracity.

In social media parlance, identifying users who like similar content is described as assembling a community. In reality, these groups are the un-community. Algorithms deliver only what they want to see, creating silos of prejudices and preferences that tear at the collective fabric required for a representative democracy. As the Russians demonstrated, organizing Americans into self-reinforcing echo chambers is ripe for exploitation.

Today, public interest groups of all political stripes monitor the mainstream media. With a public interest API they could also built public interest algorithms to accomplish the same for social media. To date, algorithms have been problem-creators.

It’s time for social media open APIs to enable problem-solving through public interest algorithms. more>

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

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

#Ciena25: The Story Behind the Founding of Ciena

By Bruce Watson – The company that would eventually become Ciena began its life as an inspiration inside the head of David Huber.  The former General Instruments engineer had an idea for how to help cable companies squeeze more television channels through their lines to end consumers.  In 1992, he set out to turn those ideas into a reality, and on November 8, 1992, the paperwork was officially filed in Delaware for the new company.

Huber immediately began searching for venture capital funding.  In late 1993, Huber was introduced to Pat Nettles, a veteran leader of several telecom companies.  By early 1994, Nettles was brought on-board to run the business side of things and was soon the company’s first CEO (though owning a doctorate in particle physics, Nettles was no stranger to the technology side of things himself).

Nettles quickly convinced Huber that it was the long-distance phone companies, not the cable TV industry, that would be the best target for Huber’s invention.

The introduction between the two was orchestrated by Jon Bayless, a venture capitalist who’s firm Sevin Rosen Funds provided $3 million in start-up funding for the business in February 1994. more> https://goo.gl/ZdVzLE

Future of 5G
By Susan Friedman, Brian Lavallée – 5G is coming, and with it comes the expectation of wireless speeds that are 100X or more what we experience today with 4G. In fact, one of the goals of 5G is to achieve maximum download speeds of 10 Gbps per user. This influx of traffic won’t come without a cost to the underlying networks that support it.

To succeed, mobile network operators (MNOs) will need more than just a new radio access network, they will also need fiber—and lots of it – to manage the massive increase in bandwidth that will come as billions more users, both human and machine, join the network.

5G is expected to be deployed strategically in different locations, especially in the early days. If consumers are expecting all 3G and 4G networks to be replaced with 5G, they’ll be disappointed. 5G is expected to complement 3G/4G where it makes sense. And depending on where service providers believe applications and use cases will be most lucrative, they can roll out speeds of up to 10 Gb/s.

This means if you’re in a rural community, chances are you probably won’t get 5G in the early days. In cities and metro areas you’ll see potential applications like enhanced mobile broadband, self-driving cars, video broadcast services, and other use cases that will require high-bandwidth and/or low-latency. So, service providers will deploy 5G in geographic areas where it makes economic sense. more> https://goo.gl/kmxQSs

Net neutrality 2.0: Perspectives on FCC regulation of internet service providers

By Stuart N. Brotman – The final outcome of this high-profile, high-impact proceeding will not be apparent until sometime late in 2017, at the earliest. Congress may also become more seriously involved at some point on the legislative front.

But without a doubt, as Chairman Pai noted in his Newseum speech, a “fierce debate” lies ahead for a number of months at least. And if past is prologue, the FCC may well receive an avalanche of comments in response to these proposed changes; the record in the Title II Order shows that over four million comments were filed by interested parties and the general public combined.

There will be no lack of political discourse, to be sure.

As we move into 2016, an unresolved national communications policy dilemma remains: whether the public-switched telephone network and the internet are parallel systems or parts of a larger ubiquitous network environment. Determining which characterization will be followed has profound consequences for regulatory treatment.

Given the emerging dominance of mobile over fixed service, if the FCC can’t regulate both, it may win the battle but lose the war. Given that a further appeal is likely regardless of which side prevails, including possible review by the U.S. Supreme Court, Congress may find itself re-emerging as the best source of guidance for the FCC. Legislative action can definitively clarify whether Congress intends for the telephone network and internet to be joined at the hip, or should continue to function in parallel with differing regulatory treatment. more> https://goo.gl/f4x8Uh

The Dawn of Automated Network Services


Ciena – Network operators are struggling to gain greater control over an increasingly complex network environment, which may include everything from virtual technologies to cloud services and legacy infrastructure. They must find a way to efficiently deliver and scale up new services and applications to keep pace with varying customer demands.

To address their challenges, many organizations are learning to embrace virtual services and infrastructure using Software Defined Networking (SDN), and Network Functions Virtualization (NFV).

However, these technological advances also introduce new pitfalls. For example, as organizations adopt SDN and NFV, they must prevent migrating from legacy hardware silos to ‘virtual software silos’—replete with their own vendor dependencies—which could hinder an organization’s ability to deliver new services or keep up with the pace of change.

The current situation underscores the need for service orchestration to help organizations break down potential silos and efficiently tie hardware, software, applications, and networks neatly together. more> blueplanet.com/resources
