What Is SD WAN | SD-WAN or software-defined wide area network
SD-WAN or software-defined wide area network is a new way to manage and optimize a wide area network (WAN). It was created to overcome the high bandwidth costs and the rigidity of MPLS services. It does that by incorporating Internet transports (such as Cable, DSL, Fiber and 4G) into the WAN and forming a virtual overlay across all transports.
