What is SD-WAN (Software-Defined WAN)?

SD-WAN has found application within enterprises that have a significant branch office footprint to simplify the deployment and management of network services across its many locations. In addition, it can lower bandwidth costs by reducing the reliance on expensive Multiple Protocol Label Switching (MPLS) links. SD-WAN can also serve as the foundation from which service providers can offer other value-added services such as firewall-as-a-service. The goal of SDN is to improve network control by enabling enterprises and service providers to respond quickly to changing business requirements.
