Advancing Peak Performance in HPC Environments

By: George Clement

Whether deployed on premises, in the cloud, or at the edge, high performance computing (HPC) solutions are now transforming a wide range of industries, including financial services, healthcare, manufacturing, oil and gas, and research and educational institutions. Often integrating artificial intelligence (AI) and machine learning technologies, HPC is able to process data and perform complex calculations at speeds up to quadrillions per second. Today, the data science applications, large-scale analytics, and recommendation engines driven by HPC are helping to detect credit card fraud, make faster and more accurate patient diagnoses, and assist scientists to find sources of renewable energy…

Monetizing 5G, Edge and Cloud Intelligently

By: Alexis Rodriguez Lorenzo

Much has already been written about the new capabilities of 5G, like low latency, massive IoT and high bandwidth, and how they will enable a new breed of applications, including Industry 4.0, autonomous driving, public safety automation and others. This horizon of opportunity will only be reached if telcos are able to bring computing power to the edge, executing artificial intelligence (AI) models where the data – often unstructured – is generated. However, reaping the business benefit from the symbiotic combination of 5G and edge will require more than just technology…

Flexible, Intelligent CDCF Networking

By: John Nishimoto

As bandwidth continues its exponential growth, service providers must adapt their networks to accommodate the ever-increasing throughput demand.  As data moves closer and closer toward the end user, multiple 100G circuits to edge data centers are the new norm, while 400GbE services will become available to more and more content delivery network operators over the next couple of years.  To keep pace with the ever-growing complexity, incorporating colorless, directionless, and contentionless functionality in flex-grid deployments (CDCF) is essential to effectively manage and operate super-high bandwidth networks…

Next Generation Cloud Security

By: Juta Gurinaviciute

According to Gartner, 99 percent of the vulnerabilities exploited by the end of 2020 were the ones known by security and IT professionals at the time of the incident. In fact, one in three breaches are caused by unpatched vulnerabilities. Software vendors are constantly publishing new patches to fix problems in software that they have sold. It is then up to the users of the software to apply the patches. Otherwise, they risk leaving themselves open to attack via the backdoors that the vendors failed to spot when building the product in the first place…

Evolving Onwards: Data Centers in 2021 and Beyond

By: Todd Murren

2020 has been a momentous year. A global health crisis has fundamentally shifted the way we live, work and communicate — perhaps forever. In the wake of social-distancing protocols, digital tools have become a day-to-day mainstay, driving our reliance on networks, data centers and the data that flows through them to an unprecedented level. In just the first few weeks of March 2020, reports observed an 18 percent increase in U.S. in-home data usage compared to the same period in 2019. Average daily data usage rates exceeded 16…

The Vital Role of Satellite

By: Brad Poulin

In the world of the industrial Internet of Things (IoT), two simultaneous phenomena are driving unprecedented convergence. Customers are demanding more data from service providers, but at the same time, crucial 2G and 3G cellular infrastructure is being deprecated. To meet this need for more data, service providers are turning to satellite to improve reliability and avoid interruption in connectivity. As satellite and cellular networks transform, the future where they coexist and work seamlessly together is the future of industrial IoT…

Paving the Path to 400G Migration

By: Koby Reshef

400G is delivering on its promise of higher capacity fiber optic transport to address the ever-increasing demands for speed and connectivity across metro, short- and long-haul network backbone infrastructure and between data centers. These new capacity levels allow carriers to maximize the value of existing infrastructure while reducing operational costs. Of course, like any new technology, 400G has its challenges. Upgrades from 10G to 40G to 100G and 200G do not require any changes to the existing carrier infrastructure; they all have wavelength spectral bandwidths that fit into existing 50GHz/100GHz grid optical filters…

Unleashing DOCSIS 4.0 for HFC & FTTH

By: Ayham Al-Banna, Tom Cloonan

HFC network evolution is one of the most complex and impactful set of decisions facing today’s operators. The difficulty is identifying potential market challenges and addressing them with the right technology in a timely and cost-effective manner. The operative term is “right technology.” DOCSIS 4.0 (D4.0) is designed to carry the cable industry into the 10G future. It will enable 10 Gbps downstream (DS) rates and 5 Gbps upstream (US) rates. It’s the first DOCSIS standard to incorporate both Full Duplex DOCSIS (FDX) and Extended Spectrum DOCSIS (ESD)—the two primary pathways for evolving today’s HFC networks…

Going Cloud-First to Accelerate WAN Transformation

By: Ashwath Nagaraj

For network architects and engineers, the WAN experience is typically seen through the eyes of telco carrier relationships. In many cases, this experience isn’t necessarily a positive one. The process of working with a telco carrier to design an enterprise WAN requires negotiating contracts and rates, provisioning and installing new circuits, addressing performance issues and outages, and managing service-level agreements (SLAs) on an ongoing basis. This can all be challenging to say the least…

Letter from the Editor: The Final Stretch

By: Scott St. John

I may be the only person who is saddened to see the end of 2020. I fully realize the challenges many people have faced over the last year and the devastating impact COVID-19 pandemic has had around the world. My sympathy goes out to everyone effected by the coronavirus in so many different, challenging, and tragic ways. I just had a different experience. For me, this year was full of unique opportunities that would not have occurred if it had not been for the unique challenges presented by the pandemic…

IT & Telecom Industry News

By: Scott St. John

A brand-new year unfurls before us, promising continued progress against the pandemic and glimpses of an emerging “new normal” globally. The final weeks of 2020 and early days of 2021 brought an array of news headlines reflecting on top trends and making predictions for what will be dominant in the new year. Amid this bevy of trends news, highlights also surfaced as the Federal Communications Commission opened its latest 5G spectrum auction, T-Mobile rolled out next-generation 911 capabilities, a new national council for AI in the US debuted, and plans for a space-based mobile communications network were launched…
