How to Right-Size Your Middle-Mile Network for Rural Broadband Growth
By Mitch Simcoe – Have you ever purchased something where you didn’t plan and anticipate your future needs correctly and you ended up needing to replace it with something larger, something that can scale with greater capacity to meet your needs? Something that leaves you with a nagging feeling, that if you had just planned better from the start it would have saved you a lot of time, money and aggravation?

For example, my son recently graduated from college and the first car he went and bought was a 2-seater red convertible with a trunk that can barely hold a suitcase. Now he wants to go mountain biking and kayaking on the weekend and realized he will need to upgrade to a truck and will reluctantly have to sell the sports car.

Well, it is not hard to fall into the same trap when it comes to planning for a Middle-Mile Network for Rural Broadband. Middle-mile networks are typically fiber rings that aggregate the traffic from service provider central offices or utility substations that connect residential customers in rural areas as shown in Figure 1. Whether it’s utility co-ops, regional service providers or municipalities, all need to plan for future broadband demand on these middle-mile networks. As we have seen during the pandemic, people living in rural areas have welcomed the opportunity to work from home; they shop, consume entertainment, and access advanced education services and critical healthcare data online. The COVID-19 pandemic has only accelerated these trends: elevating high-speed reliable broadband from a “nice to have” service to an essential one, just like water or electricity. more>

Distribute, virtualise, and optimise your datacentre infrastructure with Interxion’s ‘Managed Wave’ services
More enterprises than ever are distributing their datacentre infrastructure across multiple locations to boost their agility and to get closer to their cloud and content partners. If this is your case, you could benefit from DCI connectivity that’s super-fast, totally reliable, and highly cost effective, such as Interxion’s Ciena-powered Managed Wave solution, says Martin Phelps,
By Martin Phelps – In recent years, we have seen massive changes in enterprise’s collocation and connectivity needs. Until very recently, for example, most organisations only hosted equipment in two remote datacentres for backup or disaster recovery (DR) purposes. Additionally, compute, storage, and network equipment was nearly always hosted in the same facility to avoid latency and other issues that can impact performance.

Now, though, all this has changed.

The new normal is to distribute datacentre infrastructure across two or more geographically distributed locations, and not only for the purpose of DR. This approach to building out infrastructure is being driven by a number of key factors, including:

  1. Availability of datacentre space (or lack of it)
    Lack of space in tier-4 datacentres could be a challenge for Enterprises.  A distributed architecture allows them to overcome this challenge by hosting infrastructure in two or more tier-3 datacentres in active-active mode.
  2. Proximity to cloud providers and other partners
    With distributed architectures, enterprise customers can decide to host additional, virtualised infrastructure that is collocated with cloud ‘on-ramps’. This can minimise their latency and maximise app and workload performance.

How bold hardware and software innovations are changing the game in optical networking
How are hardware and software advancements helping network operators solve key challenges they face today?
By Paulina Gomez – Communications have come a long way since Western Union took the bold step of implementing the first transcontinental electric telegraph system in October of 1861. Fast forward 160 years and optical networks across the globe are what lay the foundation for modern communications and the way we live, work and play.

Keeping pace with today’s “new normal” customer demands for always-on, anywhere, reliable connectivity requires innovative technologies to deliver open, scalable, and programmable networks, that include next-gen coherent modems to drive down the cost of transport and reconfigurable open line systems, to be able to quickly adapt to changing customer requirements.  However, evolving towards a smarter optical network also requires leveraging advanced analytics with intelligent software automation to not only drive operational simplicity but also actionable insights based on what is happening in the network.

As our customers evolve to more open, programmable, and automated networks they need the right analytical tools at their fingertips to be able to extract the full value of their deployed network assets across all stages of the photonic network lifecycle. Paving the path towards a smarter optical network starts with an SDN domain controller like Ciena’s Manage, Control and Plan (MCP), that lays the foundation for multi-layer, automated, lifecycle operations. Advancements in hardware and software are also required to give more control to end-users so that they can fully operationalize and realize the benefits associated with a modernized network.

Updates from ITU

By Houlin Zhao – The opening of ITU Digital World 2021 a few days ago represents a special moment for the International Telecommunication Union (ITU).

This latest in our Telecom conference and exhibition series had us take stock of the incredible journey of information and communication technologies (ICTs) over the last 50 years. It was also a moment to turn to the future and commit to building the digital world, together.

My message to attendees– and the world – was to seize this moment to create a better digital future for all.

A special milestone

Fifty years ago, government and industry leaders from around the world met in Geneva for the first-ever ITU Telecom.

Over the last half-century, Telecom events have provided a window into an innovative industry at the heart of life-changing advances – from the Internet to the rise of wireless networks and emerging technologies like 5G, AI and others.

As the importance of small and medium-sized enterprises (SMEs) in the ICT ecosystem grew, Telecom events gave them a voice in the global debate and a platform to showcase their creativity. SMEs have become an integral part of these events since 2015. more>

3 unique network provider perspectives on IP/Optical convergence
What are network providers thinking about IP/Optical Convergence? Representatives from Microsoft, Telia Carrier and Cox Communications recently participated in a panel “Evolution to Coherent WDM Integration in Routers” moderated by Ciena’s Helen Xenos to discuss this very topic. Helen shares some of the interesting insights she learned during the session.
By Helen Xenos – According to a recent Heavy Reading global service provider survey, 87 percent of providers view IP/Optical convergence as important for their next-generation networks.* This is consistent with what we are hearing from customers.  There is a lot of excitement in the industry to build networks differently and offer a richer quality of experience to end users by leveraging a combination of new technology innovations – coherent pluggable optics, modern IP protocols, programmable open interfaces, and centralized multi-layer, multi-vendor software control.

What are the advantages and opportunities tied to IP/Optical convergence?  What are the networking considerations and challenges yet to overcome? I was fortunate to moderate a panel at the recent OFC Conference on this topic, where important –and entertaining—insights were shared through three unique perspectives: cloud provider (Microsoft), service provider (Telia Carrier), and multi-service operator (Cox Communications).  Here are some of the key insights I took away from the sessions. more>

The real stakes of Apple’s battle over remote work

By Shirin Ghaffary and Rani Molla – For the past several months, a fight has been brewing inside Apple, the world’s most profitable company, about a fundamental aspect of its business: whether its corporate employees must return to the office.

Apple expects employees to return to their desks at least three days a week when its offices reopen. And although the Covid-19 delta variant has made it unclear exactly when that will be, Apple’s normally heads-down employees are pushing back in an unprecedented way. They’ve created two petitions demanding the option to work remotely full time that have collected over 1,000 signatures combined, a handful of people have resigned over the matter, and some employees have begun speaking out publicly to criticize management’s stance.

Apple employees who don’t want to return to the office are challenging the popular management philosophy at many Silicon Valley companies that serendipitous, in-person collaboration is necessary to fuel innovation. more>

Who is right about inflation?
The US Fed and consumers have very different expectations about the future
By Brian Wallheimer – Inflation chatter started heating up this spring, along with inflation itself. In April 2021, the US Consumer Price Index, which measures how fast prices change, rose at a 4.2 percent annual rate, more than double the usual target rate. Then in May, the inflation rate soared to 5 percent. With the worst of the pandemic seemingly easing, US consumers were apparently venturing out again and spending at a fast clip.

The figures took inflation watchers off guard. The Wall Street Journal’s editorial page noted that Federal Reserve chairman Jerome Powell had wanted some inflation but would likely be surprised by the force of April’s numbers, saying, “Powell’s inflation ship has come in, albeit more rudely than he probably wanted.”

Financial journalists and investors, always looking for signs of how the central bank will react to signs of inflation or deflation, kicked into high gear, trying to anticipate the timing of any Fed actions.

But consumers—who actually drive inflation—seemed unfazed, apparently already operating with the understanding that prices were rising fast, and would continue to do so. Homeowners remodeling their homes during the pandemic were aware of historically high lumber prices. Home cooks felt the impact on food prices. Buyers of both new and used cars saw prices surge due to a shortage of computer chips. more>

Enabling Africa’s digital economy
Africa leads the globe in international bandwidth growth. With the fastest growth rate over the last four years and eight new cables in the works over the next few years, this is an emerging market with key network infrastructure projects to watch.
By Brian Lavallée – After Asia, the world’s 2nd largest continent is Africa, which covers 20% of our planet’s landmass. How big is Africa? Well, it’s bigger than China, India, the contiguous U.S., and most of Europe – combined. Africa is the home to almost 1.4 billion people, speaking over 2000 languages, making it the 2nd most populous continent. This population is also the youngest, with a median age of just 19.7 years in 2020.The next youngest continent is Latin America and the Caribbean (31.0) followed by Asia (32.0), Oceania (33.4), North America (38.6), and Europe (42.5).

A large, young, and populous continent means networks play an extremely important socioeconomic role to help increase critical connectivity options to close the Digital Divide and connecting Africa to the rest of the digitized world. The direct link between higher broadband and a higher Gross Domestic Product (GDP) further increases the importance of a fast, reliable, and inexpensive digital ecosystem of submarine and terrestrial networks, both wired and wireless.

From 2016 to 2020, Africa experienced the highest used international bandwidth growth by region, with a Compound Annual Growth Rate (CAGR) of over 50%, shown in Figure 1. However, Africa is still the world’s least connected continent, but it’s changing because of steady investments by African network operators. more>
