What is SD-WAN?

Written by Jarra Gruen, MDS

SD-WAN stands for Software-Defined Networking in a Wide Area Network (WAN). SDN is applied to WAN connections, providing network connectivity that lowers costs and improves resource usage for multi-site deployments, allowing network administrators to use bandwidth more efficiency with a higher level of performance without compromising data security or privacy.

How Does SD-WAN Help My Business?

Everywhere we look, companies are embracing digital transformation. Businesses now view technology as a fundamental part of business strategy, with branch offices at the front lines of this digitization. As companies look at new ways to engage customers, increase productivity, and capture revenue, they turn to the next generation of web applications and immersive content. The use of high-bandwidth applications — videoconferencing, streaming video, e-learning, video surveillance, and VDI — is growing rapidly.  The high cost of enterprise WAN connectivity, support, and personnel combined with the growth of bandwidth-hungry streaming applications and cloud-based services, is forcing many network admins to search for alternatives. 

The solution? SD-WAN.

SD-WAN is an emerging technology that offers several benefits compared with traditional, router-based WANs. Network decision makers can achieve cost savings, increased agility and simplification. IT staff gain a 360-degree view of all devices, users and applications from a single location. 

SD-WAN is a new and transformational way to architect, deploy and operate corporate WANs, as it provides a dramatically simplified way of deploying and managing remote branch office connectivity in a cost-effective manner.

It lets you identify applications, providing ubiquitous visibility of your entire network, eliminating the need for probes or additional hardware. In addition to improved performance and dependability, SD-WAN also establishes path control based on priority, application connection acceleration, and better security between branches.
