SD-WAN

SD-WAN Explained: What is Software-Defined WAN (SDWAN) and When Should You Use It? Here’s What You Need to Know.

What is SD-WAN?

SD-WAN stands for a software-defined wide area network, a virtual WAN architecture. It is a revolutionary way of routing traffic that enables organizations to integrate any combination of transport services—including MPLS but also LTE or broadband internet services—to make them operate like a much better circuit than any of the component circuits. And it uses a centralized control function to securely and intelligently direct traffic across the WAN. Research firm Gartner predicted that by 2023 more than 90 percent of WAN edge infrastructure refresh initiatives will be based on SD-WAN software/appliances. Don’t get left behind!

Back up...what’s a WAN? 

From Wikipedia: “WANs allow companies to extend their computer networks over large distances, connecting remote branch offices to data centers and each other, and delivering applications and services required to perform business functions.” WANs were incredibly important for the development of networking technologies and were for a long time the key application of networks for military and enterprise applications alike. But times are changing! Today, WANs extend to many home offices so that staff can work remotely with secure connections to their office and organization network.

Why use SD-WAN? 

Applications are increasingly migrating to the cloud, leaving traditional WANs behind. Benefits of SD-WAN include:

  • Improved WAN Optimization

  • Simplified Central Policy Implementation

  • Reduced Cost

  • Increased Reliability

  • Enhanced Traffic Management

  • Convenient Visibility into Networks and Applications

With SD-WAN, one can obtain

  • Much faster network set up—networks can be spun up, tested, deployed and made business ready in days.

  • Transport independence across broadband circuits like cable and 4G/5G LTE; and, also replacement or supplementing of MPLS. Some organizations have reduced WAN costs up to 90% by replacing fiber, MPLS and/or T1 legacy technology.

  • Improved performance of priority applications and enhanced user experience

  • Simplified operations with automation and cloud-based management

  • Improved security and reduced threats
