Open Minds, Open Source SD-WAN

What is open source SD-WAN, and how is it different from other "open" platforms we've already seen?

This was the right question for flexiWAN CEO Amir Zmora, who wanted to get into the SD-WAN space, but only if he could do something totally different.

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.

What to Know About Connecting to Your IaaS Provider

Around three in four enterprises that responded to our latest WAN Manager Survey reported having multiple infrastructure as a service (IaaS) partner. Azure and AWS were easily the most frequently cited by participants; 60% were using one or both of these providers.

With this in mind, how are enterprises connecting to their IaaS providers and why would you select one method over another? And what's the global geographic distribution of cloud providers looking like these days?

The WAN and Working From Home

For several months now, much of the world has transitioned to remote work. Where possible, knowledge workers have set up shop in home offices or kitchens or bedrooms, logging into virtual private networks and leaning on cloud services to keep business running uninterrupted.

A Changing WAN, Benchmarked

"In previous iterations of the WAN, you might have seen one large MPLS cloud, but with core sites having a larger MPLS port than edge sites. Now we're seeing a lot more technology differentiation between core versus middle tier versus edge sites." 

A self-proclaimed "data guy," TeleGeography Senior Analyst and Data Science Manager Mike Bisaha has spent years building tools to help IT managers better understand their networks' performance, design, and cost.

And he's learned a lot about the modern WAN in the process.

Everything You Wanted to Know About Sourcing Internet

The first challenge in sourcing internet is deciding what you need. Finding a balance between cost and performance is so important because in an internet world, you're going to have a lot more choice than in an MPLS world.

This advice comes from Globalinternet Chief Portfolio Officer Mike Lloyd.

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.
