Prominence of DIA in the WAN
DIA has emerged as the first choice alternative product to MPLS in the hybrid WAN. And for good reason.

Many of us are still trying to decide whether 2021 felt like ten years or six months, but there is no doubt that aspects of it were extensions of 2020.
This was no exception in the WAN world, where we saw many trends continue, such as SD-WAN rollouts, expansion of local internet breakouts, and most enterprises continuing to have a large portion of workers staying home and connecting remotely.
My colleague Elizabeth Thorne and I had a great conversation about key corporate network trends at the end of the year—now it's time to dive into the hard data.
Business broadband is no longer a connection of last resort. In fact, it is an integral part of WAN architecture.
Unlike pricey network connectivity services like MPLS and DIA, business broadband is a cost-effective option for enterprises that push more traffic to the public internet and utilize SaaS applications.
As global enterprises become more reliant on cloud—and start to break away or reduce their traditional MPLS circuits—the “middle mile” of the internet is coming into focus.
Today, I want to examine the use cases that vendors hope to address through middle mile network services. (And their basic value proposition.)
If you caught last week's special episode of the WAN Manager Podcast, you must be waiting on the edge of your seat for the second installment.
To recap, Greg Bryan and Elizabeth Thorne are keeping up their tradition of decking the halls with an end-of-year WAN review. And since 2021 was such a big year, we couldn't fit everything into just one episode.
To make up for the cliffhanger, we've packed part two with enough data and lively conversation to knock your stockings off their mantel.
With the explosion of cloud applications in the corporate network and the shift to local internet breakouts, it's more important than ever for WAN managers to understand where their data centers sit.
If you've been a loyal listener of the WAN Manager Podcast, you might remember that last year Greg Bryan and Elizabeth Thorne teamed up for a very special WAN year-in-review.
Well, they're back at it for 2021. In our latest WAN Manager Podcast holiday special, we're shaking the snow globe that is the 2021 WANscape.
“Middle mile” loosely refers to the network segment between local access and destination network.
From the perspective of a potential customer, it might refer to whatever happens between its connection with the service provider and its application in the cloud.
SD-WAN's core promise of optimizing network performance through load balancing—and cutting costs by integrating internet into the WAN—has proven attractive. And it's helped the service take root among many large enterprise network teams.
The landscape for SD-WAN vendors is vast. While the core features of SD-WAN are generally consistent, vendors vary on additional features, security, deployment models, and pricing structures.
Our SD-WAN Research Service details the different service features and pricing available across SD-WAN vendors.
