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. 

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?

You're Going to be Reading More About Managed SD-WAN

While independent SD-WAN vendors make their mark, traditional telecom service providers are rolling out their own managed SD-WAN offerings.

Yes, some have developed their own SD-WAN technology, but most carriers have partnered with an SD-WAN vendor to provide a managed SD-WAN option.

Where Are the World's Cloud Data Centers and Who is Using Them?

TeleGeography’s Cloud and WAN Infrastructure details the international wide area network (WAN) services, cloud connectivity offerings, and cloud geographies of 170 WAN service providers.

Since the 2018 update is now available to our subscribers, we thought it would be a good time to take a closer look at who is connecting to the cloud and where cloud data centers are located based on our latest batch of data.

Staring into the Luminiferous Ether (Or How Ethernet Got its Name)

Since Ethernet was invented in 1973, it has remained one of the most widely-used local area network technologies.

And as far as telecoms history goes, few modern tools have a naming story quite like Ethernet’s. Read on for the origin story of the "luminiferous ether."

SD-WAN Provider Facts for the Modern Network Specialist

Network specialists herald the software-defined wide area network (SD-WAN) as the most significant advancement in corporate networks in years.

Here’s why: SD-WAN dynamically routes traffic among multiple connections based on the performance of each link and the priority of applications using the network.

Connections may include relatively expensive, high-performance MPLS VPN links, lower-cost dedicated internet access, or cheaper, “best efforts” business broadband service. Accordingly, SD-WAN dynamically optimizes connectivity cost and application performance. (More on that here.)
