What is SD-WAN, and what does "managed" add?
SD-WAN (software-defined wide area network) connects your branch sites over any mix of links — broadband, 4G/5G, MPLS — and uses software to steer each application down the best path, with central, policy-based control. "Managed" means SD WAN managed service providers design, deploy, monitor and operate the network for you through a 24×7 NOC.
