SD-WAN

SD-WAN, or Software-Defined Wide Area Network, is a technology that uses software to centrally manage and optimize how traffic is routed across multiple WAN connections, such as MPLS, broadband Internet, and 4G/5G links, based on real-time conditions and application requirements. Instead of rigidly sending all traffic through a single expensive MPLS circuit, SD-WAN can intelligently distribute traffic across the best available link at any given moment, improving performance and reducing costs. It is managed through a centralized controller that gives network engineers visibility and control over the entire WAN from a single interface, without needing to manually configure each individual device at every site.
