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 #2: Tiered Sites Approach

Use of the internet in corporate WANs is quickly growing. And for good reason.

Not only are internet services such as DIA and broadband cheaper than MPLS, many of the SaaS applications and cloud services that enterprises have adopted have been optimized to work over local internet connections rather than through central internet breakouts.

In addition, SD-WAN has emerged as a tool that allows WAN managers to incorporate these lower cost internet services into their network without sacrificing performance or security. But not every network site (or enterprise customer) is a good fit for an all internet WAN.

In our next two scenarios, we take an approach that we see many enterprises taking—designating network sites into tiers and assigning different network services to each tier. This allows companies to add in local internet breakouts at most offices, but keep some MPLS at higher priority sites that need service level assurances. 

A 2022 Update on Interconnection Geography

I recently had the pleasure of not only attending the 2022 European Peering Forum, but also presenting my own update on interconnection geography.

Unsurprisingly, there was a lot to cover. A full 47 slides, to be exact.

Here are some highlights from my presentation.

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.

The Reemergence of Mexican Subsea

After decades without new routes, several new cables landing in the Gulf have been announced, with more undoubtedly on the way.

These new routes will provide additional international capacity, reduce dependence on a limited number of terrestrial crossings, and build resiliency in international connectivity.

But what's driving this reemergence of Mexican subsea?

Did a Laser-Powered Chip Just Break a World Record?

This just in: a laser-powered chip may have broken a world record by transmitting a dizzying amount of data through a fiber optic cable in one second.
