WAN Wargaming: What Happens When You Leave MPLS Behind?

Welcome back to our blog series on “wargaming” WAN configurations to see how product choice can affect site bandwidth and total WAN costs. If you’re just joining us, it’s probably worth going back to the beginning

When we last left off, my colleague Elizabeth Thorne covered minimizing MPLS down to the core offices. The next couple of entries, however, are going to focus on the radicals. Yes, the daring folks who decide to leave behind MPLS and go full internet.

Adding SD-WAN, Keeping MPLS

My wife has a brutal Northern Virginia commute; she drives about 80 miles a day. Recently, we decided it was time for a new car for her.

Wargaming Your WAN: MPLS-Broadband Edition

Hello and welcome to the third entry in our series about wargaming WAN configuration scenarios. We’ve made it to the MPLS-broadband edition!

Before we continue: if you haven’t read the previous entries where I introduce our hypothetical WAN and then add local internet breakouts with DIA, it probably makes sense to do that before you dive into this one. (This scenario mirrors our last, but replaces DIA with ISP-sourced business broadband.)

Adopting Local Internet Breakouts in an MPLS-DIA Hybrid WAN

Welcome to the second entry in this series on “wargaming” WAN scenarios to make sure you’re getting the most bandwidth bang for your buck. 

If you didn’t read the set-up to the series, please go back and check that out. This will all make a lot more sense if you do.

The first actual scenario we’re going to tackle is adopting local internet breakouts in an MPLS-DIA hybrid WAN. Let’s dive in.

Why Should You Model WAN Costs? Our New Blog Series Will Show You.

I recently finished Seveneves by science fiction author and telecom enthusiast Neal Stephenson.

This book tells the story of near-future humanity struggling to survive after the moon explodes and threatens to end all life on Earth. The scientific and military elite game out their way forward, running models to identify scenarios with the highest probability of survival.

This brings me to wide area networking.

Picking Your Provider: How Carrier Selection Affects Your WAN Costs

My grandfather told stories about his days as a milkman in the 50s. To a kid growing up 30 years later, the concept seemed pretty weird. Why would someone drive to your house with your milk instead of you picking it up at the grocery store with the other food?

Survey Says: SD-WAN is Growing. Our New WAN Manager Survey Has All the Details.

We wanted to understand how modern WAN Managers were solving today's biggest challenges. We were curious to learn about preferences in network design, sourcing, SD-WAN adoption—all of it.

So we asked them.

SD-WAN Full Mesh Capabilities Were a Big Draw for Henkel

Consumer products company Henkel converted a portion of its global network, primarily in Asia, to SD-WAN.

What sold them on the switch? SD-WAN’s ability to support full mesh capability and application-based routing were big selling points.

Five Insights from Enterprises at WAN Summit Frankfurt

Last month the WAN Summit came to Frankfurt for the first time. This inaugural event brought with it conversations about SD-WAN selection and implementation, cloud-based applications, and sourcing local access and broadband.

We were also thrilled to get feedback from our German audience about how they’re managing their networks, implementing SD-WAN, and juggling MPLS.

Below are five new findings from enterprise attendees at the Frankfurt summit. (For comparison, check out what we learned from our NY audience earlier this year.)

We're Surveying WAN Managers Across the Globe. Join us and Enjoy Free Access to Our Findings.

We've got an exciting project brewing here at TeleGeography.

We're conducting a brief survey of enterprise WAN managers across the globe and across different verticals. Ultimately, we're hoping to help our readers compare their networks—and future plans for their networks—to that of their peers.
