What is Software Defined Network or SD-WAN?

What is SD-WAN:
 

The software-defined wide-area network (SD-WAN or SDWAN) is a specific application of software-defined networking (SDN) technology applied to WAN connections such as broadband internet, 4G, LTE, or MPLS. It connects enterprise networks — including branch offices and data centers — over large geographic distances.

A WAN might be used, for example, to connect branch offices to a central corporate network, or to connect data centers separated by distance. In the past, WAN connections often used technology that required special proprietary hardware. SD-WAN, on the other hand, utilizes the internet or cloud-native private networks. SD-WAN decouples the network from the management plane and detaches the traffic management and monitoring functions from hardware.

Many of the new software-defined WAN offerings, for example, can be used to improve and secure internet connectivity, making it more competitive with more expensive legacy WAN technologies such as T-1 or MPLS. However, according to a Nemertes study, “78 percent of organizations deploying SD-WAN have no plan to completely drop MPLS from their WAN.” In some cases, software-defined WAN technology uses internet broadband connections to replace more expensive solutions. Virtualization technology can apply security and virtual private networking (VPN) technology to broadband Internet connections, making them more secure.
