An SD-WAN Success Story

New Case Study Highlights Faster Speeds, Lower Costs from SD-WAN

Gustave A. Larson Company had been running an MPLS network through their ISP for as long as anyone could remember. But it only offered 1.5 Mbps speeds – quite slow in an era where most people can enjoy 250 Mbps speeds at home. Those slow speeds frustrated employees and meant the company couldn’t even offer reliable guest WiFi.

On top of that, the unreliable circuits went down often. On average, a company site was going down every week – resulting in low customer satisfaction.

IT Director Rob Sunderlage knew something needed to change. But when he approached their ISP about doubling their speeds to 3.0 Mbps, he learned it would mean an increase of a hefty $245/month for each of their 52 sites. This would be on top of the $600K a year the company was already spending for their telecommunications.

In addition, working with their ISP wasn’t easy. Requests for new circuits for new office locations took anywhere between 2-4 months. Down circuits could take a day or two to resolve. Trying to push service requests through the ISP’s bureaucratic processes was a headache.

Rob needed to find an affordable solution – and fast. That’s when ITP suggested SD-WAN. See what happened next –


What is SD-WAN?

It stands for Software-Defined Wide Area Network. It’s a virtual WAN architecture that allows businesses to leverage any combination of transport services – including MPLS, LTE, and broadband internet services – to securely connect users to applications.

Why SD-WAN Makes Sense for Today’s Businesses

Today’s customers expect fast, safe internet at the businesses they visit. With global business traffic and application use on the rise, company sites have never demanded more bandwidth than they do today. Legacy business WAN links like MPLS can no longer keep up.

SD-WAN can solve the challenges of un-dependable internet infrastructure, slow speeds, and high internet costs. Some of the key advantages of SD-WAN include:

Boosted performance. SD-WAN prioritizes business-critical traffic and steers it over the most efficient route. It will send applications on a faster link or even split an application between two paths to deliver it faster.

Reduced network downtime. SD-WAN detects outages in real time and automatically switches traffic over to working links. It does it so seamlessly that users don’t even notice.

Efficient cloud use. With SD-WAN, employees can directly access cloud applications regardless of their location without burdening the core network with additional traffic. It enables branches to communicate directly to the internet.

Cost savings. According to a recent IDC survey, nearly a quarter of respondents expected to realize cost savings of 20-39% by using SD-WAN. Almost all survey participants anticipated at least some cost savings from deploying SD-WAN.

In short, SD-WANs help businesses become more productive, agile, and efficient.
