SD-WAN Overlay Definition: SD-WAN overlay is a software-defined networking (SDN) technology that creates a virtual network on top of an existing network infrastructure to optimize traffic routing and enhance security features.
SD-WAN overlay is a technology that creates a secure virtual network on top of the existing physical network infrastructure. It allows for centralized management and control of network traffic, enabling secure connectivity over potentially untrusted networks like the Internet. By using encryption and tunneling protocols, SD-WAN overlays enhance network agility, scalability, and security for organizations.
