Survey Shows Carriers Moving to SDN in a Big Way

February 01, 2019 / David Ramel

A new survey from IHS Markit illustrates the maturation of the game-changing software-defined networking (SDN) approach, which reportedly will be adopted by all respondents and is already used by 78 percent of global service providers.SDN is at the forefront of a software-centric networking transition, along with complementary technologies such as SDN for the wide-area network (SD-WAN) and network functions virtualization (NFV). While SD-WAN represents the best route into enterprise networking, the report shows carriers have already jumped on the SDN bandwagon, which in its early stages was mostly relegated to limited test cases, proofs of concept and lab experiments.
