This is the second in a series of blogs on the topic of the evolving enterprise WAN that is based on a survey that was completed earlier this year by 110 network professionals. The first blog in this series, Main Change Drivers in the WAN, discussed the level of satisfaction that enterprise organizations have with their current WAN architecture and identified the factors that are having the biggest impact on enterprise WANs. This blog will discuss how well the traditional branch office WAN architecture responds to those factors. Subsequent blogs will look at topics such as the factors driving and inhibiting the adoption of SD-WANs, the varying approaches that enterprises are taking to evaluate SD-WANs and the varying implementation and architectural options enterprises are considering.
After years in which the WAN was relatively staid, we are now in a period in which there is significant investment in the development and deployment of new WAN products and services, most of which come under the broad umbrella of Software Defined WANs (SD-WANs). The providers of these products and services promise that they offer a number of benefits, including increased agility and reduced cost. While it is difficult to argue that benefits such as these aren’t valuable, a couple of obvious questions emerge. How satisfied are network organizations with their current WAN architecture and what would drive organizations to change its current architecture?
