What are the current challenges and opportunities for today’s submarine networks? What’s next? Find out what will be covered in our upcoming webinar with TeleGeography.
Current state of the global submarine network
By Brian Lavallée – Internet traffic patterns have shifted, and volumes have surged, as the telecom industry addresses the “new normal” where people are increasingly working, learning, and playing from home. Although the global network infrastructure has bent in certain parts of the network, it hasn’t broken. This is a testament to how reliability and availability is in the DNA of our industry and is more important than ever before.
According to TeleGeography, global Internet bandwidth rose last year by 35%, which was a major increase over the previous year’s 26% growth. This increase was driven largely in response to the global pandemic and represents the largest single-year increase since 2013. It also raised the most recent four-year CAGR to 29%. Being able to connect with each other, and to machines, has consistently increased in importance, but in 2020, this took on a whole new level of importance related to our social and economic well-being.
The pace of technology innovation in the telecom industry has accelerated over the past decade in response to growing demands related to our increasing affinity for always-on broadband connectivity. Even the once closed and proprietary world of submarine networks has evolved with the advent of Open Cables, programmable coherent modems, ROADMs, active branching units, C+L band, and more recently, open APIs, intelligent data-driven automation, and analytics. Together, these amazing technologies address challenges related to network scalability, availability, and flexibility during “normal” times. They’re even more important today as we’re mandated to increasingly work and play remotely. more>

Because you asked. Adaptive IP.
In light of the digital disruption being driven by 5G, IoT, AI, and edge cloud, many of our customers have asked us to help them reimagine their IP networks in a way that allows them to scale in a simpler and more cost-effective way. We listened and answered their call with Ciena’s Adaptive IPTM. Ciena’s Scott McFeely explains how this breakthrough solution is delivering IP differently by leveraging automation, openness, and simplicity to give our customers the competitive edge they need from access to metro.
By Scott McFeely – IP, or more formally referred to as Internet Protocol, is the common language that enables billions of interconnected humans and machines to “talk” to each other on a daily basis for business and consumer applications and use cases. IP is the “language” and foundation of the largest human construction project ever created – the internet – and it works because it’s based on open industry standards.
The internet has evolved over time and will continue to do so well into the future, as more humans and machines come online with new and evolving applications and use cases, such as 5G, Fiber Deep’s Converged Interconnect Network (CIN) architecture, and IP Business Services. This means that the way IP networks are designed, deployed, and managed also needs to evolve to maintain pace.
Over the decades since its introduction in the 1970s, by the legendary Vint Cerf and Bob Kahn, IP has continually evolved to maintain pace with ever-changing application and end-user demands. This evolution has also led to new RFCs and protocols being standardized, adopted, and deployed within routers (at last count there were over 8,000 RFCs and protocols). It has more importantly led to many of these protocols associated with IP no longer being required, updated, or maintained. This is analogous to human languages where words, phrases, and even whole languages, such as Latin, are no longer commonly used over time
What do we do with these obsolete protocols? We can eliminate them from modern IP networks to reduce storage, compute, complexity, and operating costs. We call such IP networks “lean” and it allows operators to move away from traditional box-centric IP network designs running ever larger and more complex monolithic software stacks, as many traditional IP vendors have and continue to implement today.
Operators are asking for something different. They are asking for Adaptive IPTM, a simpler way to deliver IP. more>

By Prabir Purkayastha – The U.S. tech war on China continues, banning Chinese equipment from its network, and asking its Five Eyes partners and NATO allies to follow suit. It is a market and a technology denial regime that seeks to win back manufacturing that the U.S. and European countries have lost to China.
International trade assumed that goods and equipment could be sourced from any part of the world. The first breach in this scheme was the earlier round of U.S. sanctions on Huawei last year, that any company that used 25 percent or more of U.S. content had to play by the U.S. sanction rules. This meant U.S. software, or chips based on U.S. designs, could not be exported to Huawei. The latest round of U.S. sanctions in May this year stretched the reach of U.S. sanctions to cover any goods produced with U.S. equipment, extending its sovereignty well beyond its borders.
In the last three decades of trade globalization, the U.S. has increasingly outsourced manufacturing to other countries, but still retained control over the global economy through its control over global finance—banks, payment systems, insurance, investment funds. With the fresh slew of sanctions, another layer of U.S. control over the global economy has been revealed: its control over technology, both in terms of intellectual property and critical manufacturing equipment in chip making.
The new trade sanction that the U.S. has imposed is in violation of the World Trade Organization’s rules. It invokes national security, the nuclear option in the WTO, on matters that are clearly trade-related. Why the U.S. has gutted the WTO, refusing to agree to any new nominations to the dispute settlement tribunal, has now become clear. China cannot bring the illegal U.S. sanctions to the WTO for a dispute settlement, as the dispute settlement body itself has been made virtually defunct by the United States.
The battle over 5G and Huawei has become the ground on which the U.S.-China tech war is being fought. The 5G market (including installation and network equipment) is expected to reach $48 billion by 2027, but more importantly, it is expected to drive trillions of dollars of economic output over the installed 5G networks. Any company or country that controls the 5G technology will then have an advantage over others in this economic and technological space. more>
