TeleGeography Literally Explains Data Centers

We're back at it with episode three of our five-part podcast special that explains the nuts and bolts of the internet. We haven’t yet covered exactly how and where those networks meet and exchange traffic with each other and access their destinations. So today, it's data center time. Senior Research Manager Jon Hjembo was on hand to help us work through data center types, their defining features, and what happens inside these facilities. We talk about who owns these structures and how their geography informs the way the internet works.

TeleGeography Literally Explains Transport Networks

Welcome back to our five-part podcast special that literally explains how the internet you know and love works. Last week we covered the most basic question: what is the internet? Today, we tunnel deeper, exploring the physical transport networks behind this seemingly invisible, omnipresent information superhighway. Plus we get a little help from TeleGeography's own Paul Brodsky, Peter Wood, and Lane Burdette for this one From This Episode: What is the Internet?Explore our Submarine Cable MapEpisode 503 | The Total Transformation of Latin American TelecomEpisode 424 | What Happens to Cables When The Earth Moves Under Our Feet?Episode 418 | Behind the Seas: Making Our Famous Submarine Cable MapEpisode 416 | The Death of Voice Has Been Greatly ExaggeratedEpisode 404 | What Role Do Satellites Play in Global Communication?


TeleGeography Literally Explains the Internet

What is the internet? Simply put, the internet is a network of computers. Computers can only understand two things: on and off. Everything that we do on the internet is in binary—a series of 1s and 0s representing on and off—which gives instructions to your computer to do all the amazing things it does. This means that the very bottom of the internet is a system for sending those 1s and 0s over wires (or spectrum in some cases). Whatever you do on the internet—email, videos, chats—the information is translated into that binary by your devices and then transmitted via packets. We cover this process and lots more in the first episode of our five-part special to, well, literally explain the internet.


511: Wi-Fi 6 Afraid of 7?

On TeleGeography Explains the Internet, we often focus on the long-haul, zeroing in on the network portion of telecoms. Today, with the help of Tiago Rodrigues, President and CEO of the Wireless Broadband Alliance (WBA), we’re switching things up a bit. Drawing upon his vast expertise in the Wi-Fi space, Tiago steps into the hot seat to outline the key issues in the wireless LAN. This episode considers Wi-Fi 6, 6E, and 7 developments, OpenRoaming™ that allows seamless connection across different Wi-Fi networks, and Wi-Fi’s role in emerging solutions like NaaS. We also discuss the digital divide and how to best use the limited resource of spectrum to ensure connectivity in our increasingly digital world.

510: Head in the Cloud, Toes at the Edge

Today we welcome Nokia's Paul Unbehagen to the pod. Paul has a deep history in the networking world, so he approaches his role at Nokia—NE Americas CTO—from the perspective of a network engineer. Although our main topics this week are enterprise cloud and right-sizing cloud utilization, we use those as a springboard into many topics circling the state of the network in 2023. We touch on the history of the enterprise’s move into the cloud and why some companies have reevaluated their cloud strategy in recent years. As it so often does, the geography of the cloud comes up, along with Paul’s take on location and design in the cloud. This brings us to the edge—not only what it means and where it is, but some of the new and exciting use cases of what edge computing facilitates. Embedded in that conversation is also 5G and how mobile can push the network into being a central part of the business. And we can’t resist bringing up AI/ML.

509: Why 4G Is Still Relevant for Enterprise Connectivity

This week on TeleGeography Explains the Internet, we welcome SmartCIC CEO Toby Forman to the show. Toby comes to us with a global perspective on the development of fixed wireless access (FWA) and its potential as a disruptive technology in the enterprise connectivity space. After nailing down a solid definition of FWA in the market today, we run through the factors to consider when deploying FWA. Toby explains what Cellsmart—a division of SmartCIC focused on FWA—does for service providers and enterprises interested in going through this process. Next, Toby offers some real-world use cases and shares how he sees the fixed wireless and wireless markets developing over the next few years, briefly delving into the broader implications of broadband access for economic development around the world. This episode should leave you with a deeper understanding of the development of FWA, but also the ability to evaluate and plan for what is coming next.

508: How Geography Influences Network Security

Today’s TeleGeography Explains the Internet guest comes to the security world with a deep background in cloud and networks. Joe DePalo is Chief Platform Officer at Netskope, and the ideal person to help us understand how and why location matters in network security. We first identify how the network has changed over the past few years, gauging the impact on both the threat landscape and how networks perform generally. Also on the agenda: why middle mile performance and security should be part of the equation, and how lessons learned from the challenges of creating CDNs are instructive about the modern issues in network security. Finally, Joe offers a particularly interesting take on a question that comes up often on the podcast—what does it mean to have a WAN in this environment?

507: How Do Targeted Ads Work? Is My Phone Listening In?

Today on TeleGeography Explains the Internet, we're asking the big questions about mobile advertising. Luckily, Ross Flynn of the Mobile Ecosystem Forum is with us to explain, which is exactly what we do on this show. Ross has a background in digital advertising, making him the ideal person to walk us through advertising formulas that pair ads with IPs. He talks to Greg about programmatic advertising—not just what it is, but how the practice impacts the mobile market. And then we get to the fun stuff: how do these advertising practices actually impact the mobile market? Is mobile advertising evolving? Does it present unique opportunities?

503: The Total Transformation of Latin American Telecom

Luis Fiallo has been in the telecom industry for over 25 years. And for the majority of that time, he has been at China Telecom Americas, witnessing the many changes happening in the Latin American telecom market firsthand. After years of helping to drive CTA's growth in the region, Luis—now Vice President—has many valuable insights to share with TeleGeography Explains the Internet. Peter Wood, TeleGeography’s Senior Analyst covering Latin America, joins to cover the history of networks in the region, going back to the days when even intra-South American traffic tromboned to Miami and back. We also discuss the idea of directly connecting developing markets around the world, without passing through the U.S. or Western Europe, and the economic connections between East Asia and Latin America. Finally, we talk about the cloud and dig into the areas of the Latin American telecom market that Luis views as the most important to develop in the coming years.

502: Why Telecom Service Providers Need To Automate

In both 2021 and 2022, MEF CTO Pascal Menezes joined us on TeleGeography Explains the Internet to talk through the work MEF is doing on standardizing the enterprise network. This season, we welcome a new face from the same team, Stan Hubbard, Principal Analyst at MEF. Stan recently authored a State of the Industry Report for MEF, so we wanted to have him on to discuss his findings and see where the telecom industry is at with adopting new technologies. Stan first explains the drivers in the market and why telecom service providers need to automate to stay relevant and competitive. He then outlines the path carriers can take to achieve this. Next, we talk about his report and get details on the state of adoption of automation in the telecom industry, why customized or proprietary APIs are inefficient, the benefits of standardization, how enterprise drives automation, and even how blockchain will be involved in network contracts. You can hear about more topics like this at MEF's Global NaaS Event, happening October 2-4, 2023 in Dallas.

424: What Happens to Cables When The Earth Moves Under Our Feet?

How are submarine cables impacted by tectonic shifts beneath the seafloor? This week's guests on TeleGeography Explains the Internet are well-positioned to tell us. They join us from the UK’s National Oceanography Centre: Isobel Yeo, Researcher in Geology and Volcanology, and Michael Clare, Principal Researcher of Ocean BioGeoscience and Marine Environmental Adviser to the International Cable Protection Committee. Mike and Izzy are geologists specializing in the seafloor, so their research has become vital for the submarine cable community. While most cable faults are due to human activity, a fair number are caused by changes in the seafloor. This includes earthquakes, volcanoes, landslides, and even flooding on land. We discuss the myriad ways that the dynamic nature of what lies under the surface can damage cables. We even get into the history of natural disasters and communications cables going back a century or more. We get into a specific seismic event—the recent Tongan volcanic eruption—as well as ongoing threats to sub cables, including how climate change could increase risks and how we can start to mitigate them.

423: Staying a Step Ahead of Mobile Fraudsters

Our guest today is Dario Betti, CEO of the Mobile Ecosystem Forum. It's always nice to have industry association folks on the show. I've found they can pull back from the perspective of a single vendor or operator to paint a broader picture of the challenges facing different corners of the telecom industry. This is exactly what Dario does in this interview on all things mobile. Dario first explains what the MEF does (and does not do) for its members. But, perhaps more importantly, he provides a great overview of the key issues at play in the global mobile market. And what might those issues be? We talk about fraud—always needing to stay one step ahead of the bad guys—and what's happening with roaming as carriers turn off 2 and 3G networks. We get into security for mobile networks, meeting ever-increasing mobile bandwidth demand, and 5 and even 6G mobile service.

422: AI Meets The Corporate Network

Today’s episode of TeleGeography Explains the Internet is about artificial intelligence. And for that we welcome Kannan Kothandaraman, Co-Founder and CEO at Selector AI. With a plethora of cheeky, AI-generated content out there already, we don't have to tell you that AI has been in the news a lot lately. And I know "AI" is a capacious term; this week's conversation focuses on how AI/ML will actually impact telecom networks. In fact, we've talked a lot on TeleGeography Explains the Internet about the meaningful changes that have come to corporate networks over the past several years—although it's often in the context of impacting the underlay selection, cloud utilization, security, and other factors. Our interview with Kannan is all about how AIOPs (don't worry, we'll define this in the show) are an important tool for meeting the many challenges that come with a reimagined WAN.


421: What Makes a WAN Truly Secure?

I've always known Aryaka Networks as service provider with a different approach to enterprise networks—they don’t neatly fit into categories like facilities-based carrier or managed service provider. When Aryaka’s Chief Product Officer Renuka Nadkarni agreed to join me on TeleGeography Explains the Internet, I quickly had a list of questions mapped about their place in the WAN landscape. In this episode, we cover how Aryaka approaches the WAN across different services like network, WAN optimization, SD-WAN, and security. We also get a chance to chat about the state of the modern WAN, the forces that have changed it, and how those changes impact the way one should think about security. With an extensive background in security, Renuka has a clear and interesting take on what a secure WAN truly is. From This Episode: Episode 414: SASE and SecureEpisode 312: SASE Isn't Revolutionary.
