When Carriers Collaborate

Wanna look at some cool voice data?

The recent expansion of the i3forum's Insights tool has quite a bit of that. I've been itching to talk about it on TeleGeography Explains the Internet. So today we're chatting with the i3forum, a nonprofit industry body focused on "accelerating transformation across the carrier ecosystem."

Put another way: this consortium of carriers routinely collaborates on solving some of the biggest challenges facing their industry. And they have a really innovative way of sharing data among participants, to the benefit of all involved. (Non-members can participate in this data-sharing, too. More of that in our discussion.)

WAN Configurations Are Shifting

Network underlays have been in transition as more enterprises install SD-WAN services and attempt to meet the increase in cloud traffic. Companies are looking to lower costs and increase connectivity while maintaining secure networks.

All of these changes have led to a decrease in MPLS usage, but has the decline in MPLS stalled?

Confessions of a Telecom Investor

On TeleGeography Explains the Internet, I typically interview guests who work in the telecom industry or manage telecoms at large enterprises.

Not this week!

Meet Aaron Chan, Founder and Managing Partner at Recurve Capital. As an investor in the “technology media and telecom” space—or “TMT” as they say in finance circles—Aaron has something of an outside perspective.

Behind the Seas: Making Our Famous Submarine Cable Map

There's a good chance that you first heard about TeleGeography through one of our maps.

Our own Research Analyst Lane Burdette was introduced to TeleGeography when she came across our Submarine Cable Map a few years ago. Now part of the team that creates this resource, Lane is understandably stoked about this week's 2023 Submarine Cable Map launch.

It seems like the perfect time to welcome Lane—along with our incredibly talented Designer and Cartographer Larry Lairson—to TeleGeography Explains the Internet.

The Death of Voice Has Been Greatly Exaggerated

Why has it taken us this long to welcome Senior Research Manager Paul Brodsky—an A+ podcast guest—to TeleGeography Explains the Internet?

I brought Paul on to discuss our most recent voice report, but we couldn’t help getting into a whole lot more.

It's one thing to make predictions. It's another to go back and assess how those predictions shook out.

A Brief History of Networking as a Service

This week's guest on TeleGeography Explains the Internet has a deep history in networking.

Khalid Raza was involved in some of the earliest large-scale MPLS deployments. Then, after seeing the limitations of MPLS, he co-founded Viptela–diving head-first into the SD-WAN revolution.

Khalid is now the Founder and CEO of Graphiant, a Silicon Valley-based startup. In this interview, he describes how enterprise networks have changed and why we need an approach beyond MPLS and SD-WAN.

Let’s Dive Into SASE

If you've been involved in the WAN/IT infrastructure space for the past few years, you've probably heard about SASE, or Secure Access Service Edge.

The enterprise market is just beginning to integrate this new technology into network security strategy and many professionals are still broadly unfamiliar with it. As a result, it's common for WAN speakers and writers to repeatedly clarify what SASE is (and speculate on whether vendors are “SASE washing”).

In fact, our 2021 WAN Manager Survey found that only one-third of enterprises had adopted either SASE or Zero Trust. And one in ten respondents had never even heard of SASE.
