breakout year for the SD-WAN industry
Although 2019 was dubbed a breakout year for the SD-WAN industry, a fourth-quarter decline resulted in 1 percent year-over-year growth for the worldwide Service Provider Router and Carrier Ethernet Switch market. That"s much less than similar studies of the SD-WAN market, such as last year"s SD-WAN Infrastructure Forecast from research firm IDC, which indicated that the market will grow at a 30.8 percent compound annual growth rate (CAGR) from 2018 to 2023 to reach $5.25 billion.
And an October 2019 report from IHS Markit attributed a Q2 23 percent gain in the SD-WAN market -- including appliances and control and management software -- to an enterprise router replacement surge . "In our discussions with vendors, it has become apparent that most recognize SD-WAN as a mainstream technology," said IHS Markit analyst Josh Bancroft at the time. "As a result, larger enterprises have begun to refresh their legacy, router-centric WANs with SD-WAN. Vendors are capitalizing on the refresh opportunities with customers that have large bases of aging router equipment."
