SD - WAN

SD - WAN

SD-WAN is an acronym for software-defined networking (SDN) in a wide area network (WAN). SD-WAN simplifies the management and operation of a WAN by decoupling the networking hardware from its control mechanism. This concept is similar to how software-defined networking implements virtualization technology to improve data center management and operation.

A key application of SD-WAN is to allow companies to build higher-performance WANs using lower-cost and commercially available Internet access, enabling businesses to partially or wholly replace more expensive private WAN connection technologies such as MPLS.

SD-WAN is a software-defined approach to managing the WAN. Key advantages include:

• Reducing costs with transport independence across MPLS, 4G/5G LTE, and other connection types.
• Improving application performance and increasing agility.
• Optimising user experience and efficiency for software-as-a-service and public-cloud applications.
