Introduction

There is a metamorphosis brewing in Wide Area Networks (WANs), and it is Software-Defined WANs (SD-WANs).2 Driven by the digital connectedness of business operations, and the widening footprint of business applications through the adoption of cloud services, enterprise locations simply require more network bandwidth to function. Placing this requirement into perspective, consider the retail market for business data transport services (a $ billion market in the United States in 2015) as a proxy for bandwidth demand, and then contrast with gross domestic product (GDP) and employment measurements. As illustrated in Figure 1, market demand for data transport services has been increasing at an accelerating pace relative to GDP and employment. In effect, the essentialness of network bandwidth in supporting business operations and, in turn, the economy has been rising dramatically.
