What is SD-WAN? Future, challenges, benefits of SD-WAN technology

This Priority Report takes you through the basics of understanding SD-WAN technology, what it can do for you and what its future may hold.

Introduction

A software-defined wide area network, known more commonly as SD-WAN, distributes network traffic by using SDN technology to automate and prioritize routing to and from branch offices and data centers. SD-WAN can introduce elements of complexity to network management, but in this era of increasing network traffic and a demand for speed, SD-WAN is a valuable tool. For example, it allows enterprises to prioritize business-critical traffic to travel over faster, more secure connections or to set failover options for downed links. This Priority Report gathers a range of SD-WAN information and covers key topics, including what SD-WAN technology is, the challenges and benefits of SD-WAN, managed SD-WAN services and the future of SD-WAN.
