Never Fear, the 2023 SD-WAN Guide Is Here

The SD-WAN vendor landscape has changed.

Many of the familiar faces that pioneered initial SD-WAN services have been acquired, and a host of managed SD-WAN service providers have emerged as a popular option for many enterprise customers.

So in a world where information is power, a new hero has risen to provide SD-WAN vendor knowledge to those in need: TeleGeography’s 2023 SD-WAN Guide.

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.

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.

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.
