A software defined wide area network (SD-WAN) is a way of connecting offices in multiple locations. They are used to connect multiple transport services – such as VPNs, broadband internet, LTEs – simultaneously.
Traditionally, broadband Multiple Label Switching (MPLS) connections would have been needed to connect multiple locations in a single network. This is a very expensive and complicated process. Even once properly configured, the MPLS method is susceptible to failure or dropouts. SD-WAN solutions enable these disparate transport methods to be unified and their data accessed from different geographical locations, which can reduce cost and improve application performance
In this article, we’ll consider some of the top SD-WAN solutions on the market and suggest what type of organization they are ideally suited to. We’ll identify key features such as encryption, speed, and ease of setup.
