Networking resellers are seeing a surge in sales for software defined-WANs.
Software defined networking has hit the WAN market and IDC is reporting that demand will grow over the next few years.
IDC reports a gathering momentum around SD-WAN with established vendors and a growing number of start-ups providing options.
It said that there were a growing number of service providers “jumping on the bandwagon” to take a slice of a market that it expects to grow at an average pace of 92 percent a year to hit $2.1 billion by 2021.
Jan Hein Bakkers, senior research manager at IDC said that SD-WAN had emerged as one of the hottest topics in the WAN industry.
“It will become one of the key building blocks of network evolution, driving the flexibility, manageability, scalability, and cost effectiveness that organizations require in their balancing act between rapidly growing requirements and much flatter budgets,” he added.
SD-WAN also got a mention as one of the top things to look for as a major trend from Cisco in its Visual Networking Index.
It expects SD-WAN traffic to grow at a CAGR of 44 percent increase six-fold by 2021 and represent a quarter of WAN traffic.
