SD-WAN is a reset in thinking about how a Wide Area Network (WAN) should work. It’s a virtual WAN architecture, an overlay that can work with different network transport services, including broadband. SD-WAN enables organizations to centrally manage traffic using the principles of Software Defined Networking (SDN), without the limitations imposed by physical network infrastructure.
SD-WAN centralizes network control, management, provisioning and security, despite the continued decentralization of data, as businesses move to the cloud. A few companies stand apart from the rest when it comes to offering SD-WAN solutions. Cisco is the market leader, followed by Fortinet and VMware, according to a report from Dell’Oro Group.
