Example Concept: SD-WAN (Software-Defined Wide Area Network) enables dynamic path selection, allowing traffic to be routed over the most efficient path based on current network conditions. It uses centralized control to manage WAN traffic, optimizing bandwidth usage and providing enhanced security through encryption and segmentation. This approach reduces dependency on traditional MPLS circuits, allowing for the integration of broadband, LTE, and other transport methods, thus lowering costs and increasing agility.
