WAN SDN: worldwide forecast 2018–2022

Gorkem Yigit Senior Analyst, Research

"Worldwide spending on WAN SDN for software and professional services will grow at a CAGR of 44% between 2017 and 2022 to USD2.8 billion."

Communications service providers' (CSPs') deployments of WAN SDN are progressing faster than we forecasted last year because CSPs are increasingly prioritising software-defined networking (SDN) over network function virtualisation (NFV) to accelerate their automation initiatives. As a result, we have revised up our 2017 WAN SDN baseline by USD74 million and have increased our growth expectations for SD-WAN and multi-layer control. SD-WAN and multi-layer control SDN will be the focus of WAN SDN investment, growing at a CAGR of 43% and 63%, respectively.
