603: What Network Managers Should Know About AI and Machine Learning

It's 2024. We obviously had to do an AI episode of the pod.

And for that, we welcome our guest Michael Wynston, Director of Network & Security Architecture at Fiserv. 

Michael is the first esteemed member of TeleGeography Explains the Internet's four-timers club. Indeed, as I'm sure you've guessed, he's back on the show for the fourth time. And this time around he's here to help us better understand how AI is developing as a network management tool.

 

602: What to Know About Direct-to-Device Satellite Communications

For our next episode of TeleGeography Explains the Internet, we look to the sky.

Our guest is Sal Salamone, Managing Editor of Network Computing magazine. Sal joins to discuss the emerging market for direct-to-device satellite communications. 

601: The History of U.S. Telecom Policy (in Under 60 Minutes)

TeleGeography Explains the Internet is back from summer break.

We return a little older, a little wiser, and you can bet that we've done the summer reading. To that end, we're starting this season with a classic TeleGeography Explains deep dive.

The topic? U.S. telecom law! 

Greg is joined by Jeff Long, an attorney in private practice with broad experience in both the data center and telecom industry. 

TeleGeography Literally Explains the WAN

Over the past five weeks, we've endeavored to explain precisely how data moves around the world, covering the basics of internet, transport networks, data centers, and the cloud along the way.

Today we answer our final, lingering question: What is a WAN?

First, let's get definitions out of the way. WAN stands for wide area network, which came out of the term LAN, or local area network.

Today's episode will help you brush up on the evolution of the WAN. We'll also hear from Brianna Boudreau, TeleGeography's current SD-WAN guru.

TeleGeography Literally Explains the Cloud

You may have heard a popular saying: There is no cloud, only other people’s computers. 

To explain how it works, Senior Research Manager Patrick Christian joins us to talk cloud. We explain what it means to get something "as-a-service," hyperscalers, CDNs, and how companies get to the cloud.

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

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.

• Episode 504 | How NaaS Relates to SDN and Automation
• Episode 409 | The Digital Divide Episode

• Episode 313 | The Need for NaaS

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.
