The Digital Divide Episode

James “Jim” Capuano has logged over 30 years in the telecommunications industry. And he's the CEO of Horizon, a service provider with more than 125 years of telecommunications experience.

I recently asked Jim to share some of his knowledge on TeleGeography Explains the Internet. In this episode, we view middle mile problems and solutions from a provider perspective and discuss how the middle mile is developing in the current WAN environment.

Orchestrating the Service Lifecycle

In 2021, MEF CTO Pascal Menezes walked us through the work MEF is doing on standardizing the enterprise network.

Nearly a year and a half later, Pascal is back on the pod to discuss what MEF has been doing since then.

Our first topic: Lifecycle Service Orchestration. What is it, how has it progressed, and what does it do for the carrier community?

Key Findings From Our Latest WAN Market Size Report

After tracking the WAN market size in 2020 and 2021 with our WAN Market Size Report, we began to think beyond the market as it is today.

What if we could predict what the future of the WAN market would hold?

Unraveling the Fabric Providers of Reality

This week, we're talking about NaaS.

Sure, we've covered NaaS in various contexts on TeleGeography Explains the Internet, but this episode focuses on fabric providers and where they're headed.

For that, we're so glad to have on our outspoken and super knowledgeable friend Michael Wynston, Director of Network Security Architecture & Automation at Fiserv.

Hypothetical Network Series #3: BYOB Internet WAN

So far, we’ve looked at integrating DIA and business broadband into a hybrid WAN. But there are a host of other network services that corporate networks teams have employed in their network transformations.

Our next scenario represents an Internet-first WAN with data center sites, a BYOB (bring your own backbone), if you will.

This customer may be someone with their own servers looking to build a fiber loop around the globe to connect them, even if they are at a neutral facility.

Unpacking Network Observability

If you want to do a proper review of the state of the corporate WAN—in light of digital transformation, cloud, SD-WAN adoption, and MPLS utilization—there's no one better to talk to than Phil Gervasi, Director of Technical Evangelism at Kentik.

Lucky for me, he was this week's guest on TeleGeography Explains the Internet.

Hypothetical Network Series #1: High Bandwidth MPLS

Back in 2019, we built a hypothetical network to illustrate how different network configurations might affect total cost of ownership (TCO).

Now that it's nearly 2023, we got to thinking, if Cheaper By the Dozen can get a reboot, why can't our hypothetical network series?

So here we are. The world has changed a lot in the last three years, and WAN managers are also facing a number of changes.

What Role Do Satellites Play in Global Communication?

It's kind of an inside joke among telecom insiders.

We've all had that conversation with a friend or family member where we've told them the hard truth: the internet is actually made up of wires and satellite plays a very minor role in global communications!

Okay. This remains true, but today on TeleGeography Explains the Internet we're going to flip the script and look to the sky. Let's do it. Let's talk satellites!

Data Centers and the Opportunity at the Edge

When I reached out to today's podcast guest—Jim Poole, Vice President of Business Development at Equinix—about being on the show, I asked if he'd be willing to dig into NaaS or edge data centers.
