Editor's note
Software-defined networking may have started in the data center, but it’s since moved to the wide area network -- and with its promise to improve branch network connectivity while lowering costs and increasing agility, SD-WAN architecture is the most popular new kid on the networking block.
A plethora of startups and established industry players have now crowded on the scene, all offering variations on the same theme: technology that uses SDN principles to dynamically aggregate multiple WAN links, thus stepping up performance and decreasing reliance on costly MPLS connections. This essential guide will help you sidestep vendor hype and explore whether you’re ready for SD-WAN to move into your network.
