What is a Transport Network?

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.

What is the Internet?

If you've caught TeleGeography's podcast, you'll know that we endeavor to explain the business behind human connection every week. We've chatted about Wi-Fi, WAN, and everything in between

We've audaciously called our show TeleGeography Explains the Internet, but we've never properly explained how the internet works and how bits get pushed around the globe. Until now.

That's right. We decided it was time to, quite literally, explain the internet.

Why Do You Need a New Network Security Posture?

“Enterprises have shifted connectivity to the internet, mostly with DIA. This changes the security environment away from private MPLS to the best-efforts public internet.”

Last week, Senior Manager of Enterprise Research Greg Bryan joined Ciena's Brian Lavallée for a live webinar all about submarine cables and security.

For his part, Greg described how the enterprise network has shifted in the last few years, how carriers and enterprises have responded to these changes, and why geography matters in network security.

The Red Sea: A Key Subsea Cable Crossroads Under Siege

The Red Sea is a global hot spot at the moment due to repeated attacks by Yemeni Houthi rebels against commercial shipping vessels.

While this inlet is a strategic location for global shipping, it also plays a vital role in global communications networks.

The State of the Network in 2024

Another lap around the sun, a new TeleGeography State of the Network Report—a tradition we’ve kept since 2017.

No seven-year itch for us, though; we’re just getting started. As the world of telecommunications continues to turn, each edition brings even more to report on than the last.

How Is the Global Network Keeping Up With Demand?

By any measure, the global bandwidth market is thriving. International bandwidth demand has nearly doubled from 2020 to 2022, and has now reached 3.8 Pbps.

Meanwhile, the lit capacity on major submarine cable routes continues to soar, keeping pace with demand.

How? Is the network getting faster?

Not quite. Think bigger highway, not faster cars.

Watch Now: The Cloud Under the Sea

If you caught Research Director Alan Mauldin’s Submarine Networks World presentation this year, then you know how well-versed he is in submarine cable geopolitics (and in cable knowledge in general).

So you shouldn’t be surprised to see Alan sharing his expertise throughout ABC News’ exciting new submarine cable documentary, The Cloud Under the Sea.

This hour-long program “uncovers the shadowy world of telecommunication sea cables.” Watch it below.

The Data Center Industry Faces New Obstacles

Recently, we’ve been closely monitoring the intensifying pressures of insatiable demand and supply constraints in key data center markets.

Supply constraints have come in the form of both short-term and long-term challenges.

In the short term, supply chain disruptions have hindered development timelines. On the long-term side, regulators and utility providers have begun taking a hard look at the data center sector and how to grow it sustainably going forward. In some cases, these entities have severely disrupted development during the interim period.

None of these challenges have been resolved. And as we move through 2023, another major disruptive component has been added to the mix—the accelerated growth of generative Artificial Intelligence (AI).

Want To Retire in Your 20s? Become a Submarine Cable

Wouldn't it be great to be fully retired before your 30th birthday?

Because they are engineered with a minimum design life of 25 years, it's common for the submarine cables that keep our world connected to experience this luxury.

Let’s talk about why, and what happens to cables after they reach retirement age.
