SD-WAN
Software-Defined Wide Area Network
Centralized, software-driven control of WAN connectivity.
SD-WAN applies software defined networking to the wide area network, centralizing control so traffic can be steered intelligently across MPLS, broadband, and cellular links based on policy and application needs. It lowers cost and improves performance for branch sites and cloud bound traffic compared with traditional fixed circuits. Security features such as integrated encryption and segmentation are often layered on, and SD-WAN commonly serves as the connectivity foundation within a broader SASE architecture.
Looking SD-WAN up is step one. Getting tested on it is step two.
