The Results Are In: 2022 WAN Manager Survey

Nearly three years out from the start of the pandemic, enterprise networking is starting to stabilize.

Let's celebrate with some insights from our latest and greatest WAN Manager Survey.

Preparing the Next Generation of Infrastructure Professionals

Rohan Singh knew his future was in networking and communication when he saw his first network diagram at around 12 years old. That's probably why he feels like he's been involved in networking for most of his life.

Now Vice President of Client Services at Marlabs, Rohan joined us at TeleGeography Explains the Internet to talk about all that goes into the modern digital transformation.

Unpacking Telecom Predictions of the Past

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

One month into 2023, Mattias Fridström, Chief Evangelist at Arelion, very kindly agreed to scrutinize his 2022 forecast with us.

What Do You Get When You Cross GEO Satellites and SD-WAN?

While most planned satellite constellations used for connectivity fly in low earth orbit (LEO), some fly in geosynchronous equatorial orbit (GEO) and circle the earth from a much further distance.

Because of this distance, LEO satellites tend to have lower latency and higher bandwidth than their GEO counterparts.

So when MetTel tried to cross its SD-WAN offering with HughesNet's GEO connection, it got latency.

More on this story and our other January telecom reading recs below.

SASE and Secure

This week on TeleGeography Explains the Internet we welcome Jeremiah Ginn, Software Defined Cybersecurity Evangelist at AT&T and author of Diving into SASE.

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.

The WAN That Was: What We Learned From Enterprise Networking in 2022

You thought we were going to do a major end-of-year review of telecom trends and leave out all things WAN? No, no. Not on our watch.

Host and Senior Manager of Enterprise Research Greg Bryan broke out the data for this bonus New Years episode of TeleGeography Explains the Internet.

A Low-Tech Solution to High Data Center Electric Bills

Back in July, we touched on how UK data centers were struggling to stay cool through unseasonably warm temperatures.

Five months later, our telecom reading list starts off with a very different story: Equinix is considering a multi-year project to raise its data center temperatures.

Feeling '22: A Telecom Year in Review, Part 2

We're looking back at all things telecom in 2022. And we're doing it the best way we know how: rounding up our analysts and inviting them to discuss major findings in their areas of research on TeleGeography Explains the Internet.

If you want to dive in from the very beginning, you can listen to part one over here. And if you're ready for more, keep scrolling.

Part two takes us on a journey through the last 12 months of submarine cable news, SD-WAN, security, and major world events that intersected with telecom infrastructure.
