Carrier SDN, NFV investments to rise to $22B by 2020, says analyst

Service providers' ongoing movement to SDN and NFV, according to SNS Research, could grow at a CAGR of about 45% over the next three years.

By the end of 2020, the research firm said in a new report that this growth will drive nearly $22 billion in SDN and NFV investments.

Besides addressing the ongoing capacity demand for mobile and wireline broadband services, the advent of SDN and NFV can reduce capex and opex burdens faced by service providers to handle emerging demands by reducing the reliance on proprietary hardware platforms.
