Underlay Changes: MPLS vs. DIA Pricing

In the past few decades, the corporate WAN has undergone a few massive reformations.

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.”

Three Facts From Our New WAN Market Size Report

If you've perused our research catalog lately, you'll know that we have a new WAN Market Size Report.

In this offering, we present a data-driven, granular view of market opportunity for underlay of the corporate WAN. (More about that here.)

To understand where the larger multinational WAN market stands today, we're sharing three takeaways from the first edition of the WAN Market Size Report. 

New WAN Market Size Report Shows a Global WAN Market Worth $75.9 Billion

There’s no question that the enterprise wide area network (WAN) market is in a state of flux. 

We’ve seen multiple disruptions in the way multinational corporations construct WANs: a move toward cloud computing, migration of the data center away from corporate premises, and, especially, the introduction of SD-WAN.

To help carriers, vendors, and enterprise IT infrastructure teams understand how these changes will affect the business of telecom, we’ve created the new WAN Market Size Report.

WAN Pricing Mythbusters: Do Tier 1 Carriers Charge More for DIA?

My colleague Elizabeth Thorne and I have been working on busting–or confirming–WAN pricing myths that we’ve heard in the wild. Last time I took on MPLS and DIA price convergence. 

I’m going to stick with DIA for this post, too.

Specifically, I want to know if Tier 1 IP providers charge more for DIA service than others. This is a myth I’ve actually argued in favor of in the past. It is certainly true that some carriers can provide a higher level of service, i.e. traffic that takes the fewest hops between destinations, and maybe even traffic that never touches another provider’s network. This might warrant higher prices.

WAN Pricing Mythbusters: Is MPLS Priced Like DIA?

In case you missed my previous post, we here at TeleGeography love busting telecom myths. But we haven’t turned our analytical tools toward common WAN pricing myths—until now! 

In this second installment, I’m going to investigate whether MPLS IP VPN and dedicated internet access (DIA) prices have become one and the same.

WAN Pricing Mythbusters: Is Local Access 50% or More of the WAN?

We have a years-long tradition of Mythbusting here at TeleGeography. But it occurred to me that we’ve never tackled any of the WAN pricing myths floating around out there. That’s why I decided to do a series addressing some of the things I hear from WAN-sourcing and WAN-selling professionals. 

Let’s see if these WAN pricing myths stack up against the data. 

First up: is it true that, particularly for traditional MPLS networks, local access can account for upwards of 50% of the total cost of ownership (TCO) of WAN components?

Schrodinger's MPLS and Why Predicting the Future is Hard

Predicting the future is hard, especially when it comes to complex markets with disruptive variables that are difficult/impossible to model. In his excellent book Thinking Fast and Slow, Nobel winner Daniel Kahneman provides stark examples of how bad humans can be at doing just that. 

In this excerpt, Kahneman details how he tracked the performance records of 25 professional wealth managers across eight years. He found that “[t]he results resembled what you would expect from a dice-rolling contest, not a game of skill.”

On TEMs: You Can't Benchmark Your Network if You Don't Understand What You're Buying

Let's talk about telecom expense management, better known as TEM.

TEMs are designed to make untangling telecom investments a little easier. For larger organizations with bigger telecom bills, this can be huge for streamlining costs and saving dollars. (More on that here.)

But why bring up TEMs? Why do we think WAN managers might be interested?

COVID-19 and the Impact of Remote Work on WAN Managers

At this point, the spread of COVID-19 seems inevitable in much of the world. Working from home, if possible, is more than just a good idea. It’s a mandate from employers and governments around the globe. 

While many folks are considering the social and business implications of a potentially permanent increase in remote workers, at TeleGeography we’re of course thinking about what this means for WAN and IT infrastructure managers worldwide.
