Software-defined WAN (SD-WAN) is a network traffic distribution solution that employs software-defined networking (SDN) concepts to automatically find the most efficient way to route traffic to and from branch offices and data centre sites across wide area networks (WAN).
Technology has generated new sorts of enterprises and disrupted entire industries during the last two decades. As enterprises rely more and more on mobile devices, IoT, and media-rich apps to accomplish a wide range of operations in order to gain productivity, efficiency, and cost savings, the current shift from MPLS-based networks to Software Defined Wide Area Network (SD-WAN) is such a game changer.
SD-WAN is a game-changer in a market that has been stagnant for the previous 20 years, focusing on an MPLS Network topology. SD-WAN is the outcome of the convergence of two new technologies:
