SD-WAN (software-defined wide area network) is a technology that connects branch offices, data centers and cloud services over several links, such as broadband internet, MPLS (Multiprotocol Label Switching) or cellular, and uses software to pick the best path for each application. For example, it routes video calls over the most stable link and other traffic over broadband.
