The way SD-WAN technology works provides significant advantages to WAN. Traditional WAN technologies involve installation of proprietary hardware or expensive fixed circuits. WAN infrastructure is quite complex, consisting of routers, firewalls, WAN optimizers, WAN path controllers and other components.

SD-WAN takes out much of the hardware, offering connectivity and services through the cloud. It delivers unified communications and data applications through integration of multiple connection types, like broadband internet, Multiprotocol Label Switching (MPLS), and Long-Term Evolution (LTE). SD- WAN also integrates the entire WAN into a single interface, which makes handling issues in the network easier.

Overall, the goal of SD-WAN is simplification and the creation of a real-time data network without as much physical networking. The end idea is that, after deployment of SD-WAN devices, setting up the technology would be as easy as setting up Wi-Fi.
