This IDC Survey analyzes results from the software-defined wide area network (SD-WAN) and virtual network function (VNF) sections of IDC's 2018 U.S. Enterprise Communications Survey, an online survey of United States–based businesses fielded in August 2018. These portions of the survey explore trends driving these markets, adoption rates, leading use cases, and implementation strategies for these important technologies.
"SD-WAN continues to be one of the fastest-growing segments of the network infrastructure market, driven by myriad benefits that United States–based enterprises reported to IDC in the U.S. Enterprise Communications Survey. Another trend highlighted in the survey results is the growing interest in VNFs at the enterprise edge. Enterprises report that deploying both SD-WAN and VNFs increase agility, improve security, and lead to overall network efficiency." — Brandon Butler, senior research analyst, Enterprise Networks at IDC
