Behind the Headlines: Recent Submarine Network News, Explained

This year has been—and will continue to be—a busy one in the submarine networking industry. Several new submarine cables have already been announced, deployed, or put into service.

How Do You Become Africa's Largest Telco?

For better or worse, MTN has been unafraid of doing business in locations experiencing war, political turmoil, and disaster.

This strategy has made them one of the biggest telcos in Africa—but it hasn't come without cost. The Wall Street Journal's recent profile earns the top spot on our list of monthly reads.

Wargaming an MPLS Core Hybrid: How to do SD-WAN Without Losing MPLS

Howdy folks, Greg is out on vacation (adventuring in the magical kingdom of Orlando, Florida) so I will be filling in for a bit to continue our series on “wargaming” WAN scenarios.

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.

Our new e-book contains everything you wanted to know about network benchmarking.

Probably a few extra things, too.

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.)

Some of the Biggest, Most Interesting Stories in Telecom Are Happening in Africa Right Now

When we look through some of the most interesting telecom stories from the last month, a theme emerges.

There's a lot of submarine cable and data center news coming out of Africa. 

We've selected stories about Facebook's plan to bring cheap internet to Africa, as well as a profile on Equiano, Google's new private subsea cable connecting Portugal and South Africa.

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.

Building and Managing Security Empowered SD-WAN

The benefits of SD-WAN are apparent: more bandwidth, local breakouts, flexibility, etc. That being said, the larger attack surface makes it vital for security to be at the forefront of any modern deployment.
