From Land to Sea to Cloud
By Brian Lavallée – Submarine networks carry over 99% of all telecommunications traffic between continental landmasses making them easily classified as critical infrastructure. There’s also no “Plan B” for these submerged assets, so they’ll continue to act as the jugular veins of intercontinental connectivity for years to come and will thus require constant technology innovation to reliably and securely maintain this pivotal role.

But exactly what traffic is transported back and forth on seabeds around the world? According to respected industry analyst firm TeleGeography, it’s increasingly Data Center Interconnection (DCI) traffic, and LOTS of it.

It’s projected that Internet Content Providers (ICPs) will soon account for the majority of submarine traffic in all regions of the world. Impressive for a group of companies that just over a decade ago, were essentially non-players in the submarine networking market.

Given the astonishing amount of DCI traffic added to traditional wholesale traffic, several new technologies were introduced to address this extraordinary growth, which sits at around 40% CAGR worldwide, according to TeleGeography. more>

Debunking 5 common myths about 5G
By Brian Lavallée – When 5G begins to roll out, it will likely start in a select group of countries like the United States, South Korea, China, Japan, and India. However, we won’t be saying goodbye to 4G anytime soon. The truth is, 5G was never intended to replace 4G, unlike 4G that was expected to replace 3G (but never really did). When 5G rolls out, 4G and its multiple variants will still play a key role in the network — particularly for less bandwidth-heavy applications and use cases.

This means operators need to plan for both 4G today and 5G tomorrow, as both will coexist and share same network resources for the foreseeable future.

There’s no doubt: higher download speeds are a big part of 5G and is what most people are most excited about but equally important is that 5G will offer up to 10 times lower latency than 4G. It is this combination of faster download speeds and reduced latency that opens up new use cases, such as augmented reality and virtual reality.

Since the 5G standards are not complete, there is no such thing as a “5G product” today. To get around this, some talk about having 4.5G (better than 4G, but not quite 5G) products that meet the current draft standards being proposed today. However, it is important to note; you can’t credibly make this claim because if you build something based on where the standards are now, there is still a chance the product won’t be able to adapt, such as via software upgrades, when standards are approved later. more>

5 ways to future-proof your network today to support IoT tomorrow
By Rob Tomkins – There is no getting around the fact that networks are seeing an explosion of data coming from “smart” objects that connect the physical and digital worlds. In fact, IHS forecasts that the market will grow from 15.4 billion devices in 2015 to 75.4 billion in 2025. Despite this increase in data, and no matter what new IoT technology or application is announced, users’ expectations remain high — networks must be up and running constantly and bandwidth must always available.

Plus, now that IoT, including Industrial IoT, is becoming more intertwined with mission-critical services such as smart grids and emergency alert systems — the stakes are even higher. Even the slightest network latency or jitter goes beyond a simple inconvenience and has the potential to cause life-threatening situations.

The time is now for service providers, enterprises and cities to get their networks in shape to handle the increase in bandwidth requirements, as well as prepare for what is to come tomorrow. Unfortunately, while it’s a simple concept, it’s not such a simple task.

In many ways, the current IoT landscape resembles the Wild West. more>

Ethernet Adventures: Making Progress with an Old Friend – Good ol’ Ethernet
By Chris Sweetapple – This was not his only network problem. The traditional Local Area Network (LAN) connections were plagued by latency and jitter. Users simply would NOT use underperforming applications or services.

To our hero, this is not good enough. His business’ users have high expectations. They want connectivity options and performance that are reliable, secure, on-demand and cost-effective. Our hero knows that the network can play a very valuable role. Only the network can manage the quality of the connection and ensure optimal end-user experience for everything else. This makes the network more important than ever – and a differentiator for the business; but only if it can provide the best possible assurance for each service by ensuring latency, security and speed.

With his friend, advanced business Ethernet, our hero can mitigate legacy network complexities, sidestep the public internet and increase network performance. He can also maintain links to traditional networks and applications while keeping pace with fluctuating usage demands. Our hero can now modernize his network. He can move toward next-generation operations and embrace hybrid capabilities for a variety of uses. Connections can be increased from 1G to 10G and higher – up to 100G to connect to data centers or transfer massive files like MRI scans, uncompressed video, design prototypes, and so on. more>

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
