The Adaptive Network: Why automation alone isn’t enough
By Keri Gilder – Just imagine, instead of 70, your heart rate was at 100 beats per minute. This could be a warning sign that you are on the verge of having a heart attack.

If your doctor were to get this information in real time, they could check the readings against your medical records and see that this is completely out of the norm and then warn you to seek medical assistance immediately.

However, if your personal trainer received that same information, would they reach the same conclusion as your doctor? Your trainer has access to a different database, which might show your resting heart rate as well as the rate during high-intensity training. Knowing that you are likely exercising, they would instead conclude that there is no need to go to the hospital after all.

This clearly demonstrates that just accepting raw data without filtering and proper analysis is no longer good enough and can potentially have serious repercussions. Instead, it is critical that we have diversity of thought when it comes to how we interpret data.

This is not just true for our health or other day-to-day scenarios, but can also be applied to the communication networks that carry and house our information. more>

Guidelines to Achieve Digital Transformation

GSR-18 BEST PRACTICE GUIDELINES ON NEW REGULATORY FRONTIERS TO ACHIEVE DIGITAL TRANSFORMATION
itu.int – Digitization is increasingly and fundamentally changing societies and economies and disrupting many sectors in what has been termed the 4th Industrial Revolution. Meanwhile, ICT regulation has evolved globally over the past ten years and has experienced steady transformation.

As regulators, we need to keep pace with advances in technology, address the new regulatory frontiers and create the foundation upon which digital transformation can achieve its full potential. Being prepared for digital transformation and emerging technologies such as Artificial Intelligence (AI), the Internet of Things (IoT), Machine to Machine communications (M2M) and 5G is fundamental.

Advances in technology are creating new social phenomena and business models that impact every aspect of our personal and professional lives – and which challenge regulatory paradigms. M2M, cloud computing, 5G, AI and IoT are all bringing further profound change. Recognizing the potential of emerging technologies and the impact that policy and regulatory frameworks can have on their success, regulators should encourage a regulatory paradigm pushing frontiers and enabling the digital transformation. more> draft doc (pdf)

Why the Secret Behind Strong Early Adoption of 400G Technology is … 200G

By Helen Xenos – This month, we shipped our 5,000th 400G-capable coherent optical transponder, confirming our prediction that the use of 400G technology is ramping 3 times faster than 100G.  What may come as a surprise, however, is that the dominant application driving 400G deployments is not 400G, but 200G (long haul-datacenter interconnect to be precise).

Why? The technology that enables 400G wavelengths has a lot to do with expanding the application space for 200G as well.

To fully understand the demand drivers for 400G, it’s important to clarify the various ways 400G is defined. The term “400G” is quite popular in today’s optical networking conversations, but can also have different meanings depending on the context in which it is being used.

So, which applications are driving 400G deployments? We hear so much about the fast-growing metro WDM market, 400ZR and the need to maximize capacity for short reach DCI applications, that intuitively you would think this is the “sweet spot” application.

In fact, the most popular use case we see for early 400G adoption is to support the rise of 200G long-haul for aggressive DCI network builds. more>

4 Data Center Interconnect Developments You Need to Know
By Kent Jordan – The Data Center Interconnect (DCI) market is evolving rapidly and new compact, modular devices have been introduced to help network operators quickly and easily deploy new capacity to keep up with demand. But, as the adage says, “the more things change, the more they stay the same”. So, what’s new with DCI and what hasn’t changed in the last year?

One thing that hasn’t changed is the need for more interconnect capacity. Interconnect bandwidth growth is still on the rise, and it’s growing rapidly. By 2020, interconnect bandwidth has been forecasted to grow up to 5,000 Tbps, with double-digit growth rates across a variety of industry segments from Cloud and IT to Healthcare and Energy. All are poised to experience large capacity growth in the coming years, which means many of the same challenges from the past year still exist.

Network operators are challenged with keeping up with growing demand and offering content and/or services globally. They also have a need for automation to speed bandwidth activation and improve their customers’ quality of experience. On-going operational costs remain a challenge as well, with a need to reduce footprint and power consumption. more>

Variable Fonts Are the Future of Web Type
By Mandy Michael – A variable font is a single file that acts like multiple fonts. Variable fonts can improve page-load times, but their appeal goes way beyond that: Site visitors get an improved reading experience, and designers get greater creative freedom.

While it’s still early days, some software applications—including the latest Illustrator and Photoshop—and many web browsers do support the technology, and more will follow. It’s a good time to understand how variable fonts work and how to use them in your web designs.

Inventive type designers aren’t restricting themselves to expected variations, such as weight, width, or italic. They’re creating variations that address effect, readability, and style. more>

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>
