When business managers shop for new telecom services, more often than not they encounter the networking term SD-WAN.  So what is SD-WAN?   SD-WAN is an acronym for Software Defined Wide Area Networking.  This term represents a relatively new development in the telecommunications industry, and describes the functions of optimizing data transport and Internet transit services.  It incorporates Software Defined Networking (SDN) applications into WAN connectivity solutions.  SD-WAN functionality, physical WAN links from multiple vendors, and various transport types (cable, copper, fiber, wireless), can be aggregated via customer premise equipment to more efficiently carry WAN network traffic.  From a practical point of view, a company can save significantly on telecom expenditures by adding less costly broadband links into its network infrastructure.  This enables a company to price shop for a least cost end point connection(s) at each WAN edge location where Internet service is needed.  Traffic no longer needs to be backhauled to a corporate headquarters location for users to access hosted applications and services.  The result is a better user experience for company employees working in a distributed data environment.
