TeleGeography Deep Dives: Cloud and WAN Geography

The enterprise WAN is increasingly built on an underlay, using various transport services from a variety of providers. So it's more crucial than ever to understand the footprint geography of your carriers, ISPs, NaaS providers, and cloud service providers.

We've got you covered. On Thursday, June 17 we're assembling a team of experts for a morning roundup of all things cloud and WAN geography.

Submarine Cables: It's Not Bitcoin

We often say that we'll be taking a "deep dive" into an issue at the beginning of our WAN Manager Podcasts. Today we almost mean that literally, as Greg welcomes TeleGeography Research Director Alan Mauldin to talk about submarine cables.

I'm Just the Middle Mile Man

We're going back to the middle. The middle mile, that is.

Like many telecom terms, this is one that you might have to follow up with “what exactly do you mean by that?”

What Role Will MPLS Play in the Future of the WAN?

The average enterprise network had MPLS running at 82% of sites in 2018. That fell to just 58% in 2020. About one-third of those networks have active backups for their MPLS service—a quarter of them have passive backups.

Looking at these numbers, we have to ask: what role will MPLS play in the WAN moving forward?

WAN Manager Survey Data: Let's Do The Time (Series) Warp

In today's episode of the WAN Manager Podcast, Greg is joined by Analyst Elizabeth Thorne to dig into our latest WAN Manager Survey data.

From SD-WAN adoption stats to network configuration preferences and MPLS trends, the pair covers a lot of ground. If you want to learn more about the survey, the people who take it, how we run it, and what the top-level findings are from our newest batch of data, punch that play button.

The Art of Zen and Network Monitoring

Look alive. Our latest episode of the WAN Manager Podcast is all about network monitoring.

SmartNICs, Explained

Most of our listeners are probably familiar with network interface cards (NICs, if you're savvy). But what about SmartNICs?

Virtual Event: The WAN Evolution Meets the Cloud Generation

We like to keep our readers up to speed on virtual events and conversations that might be of interest. So mark your calendar for April 8 at 11 a.m. EDT/8 a.m. PDT, because we're teaming up with our friends at Netskope to host a discussion on the WAN evolution.

SD-WAN Adoption is on the Rise

With the release of our latest WAN Manager Survey results comes new SD-WAN insight.

In short? The number of enterprises deploying SD-WAN increased significantly between 2018 and 2020.

New WAN Manager Survey Results Show MPLS is Holding Strong

Technology such as SD-WAN, migration to the cloud, and the sudden surge of remote and distributed work have upended the modern WAN.

The composition of the underlay, flow of traffic, end points of workers, and security postures are all undergoing a massive shift. Like the protagonist in Canadian power trio Rush’s hit “Tom Sawyer,” WAN managers are realizing that “changes aren’t permanent, but change is.”
