Adoption of Software-Defined Networks Is Growing
The adoption of software-defined networks (SDNs) is growing rapidly in enterprises, according to a recent survey from Network Instruments. The accompanying report, the "Seventh Annual State of the Network Global Study," covers a wide range of IT topics, including the elevated profile of unified communications (UC) and bring-your-own-device (BYOD) initiatives, but SDN is growing at a strong pace for a relatively new technology. Surprisingly, there's no standard definition to describe SDN. More than one-third of the survey participants described it as the automated provisioning of network resources, while another quarter said it's the replacing of tools for network traffic optimization and acceleration with software. However, 37 percent of respondents said SDN is "undefined, like a trip without a map." Clearly, SDN remains a work in progress. "As with any emerging technology, IT management is grappling over the definition of SDN, as well as its benefits and importance to the organization," says Brad Reinboldt, manager of product marketing for Network Instruments. More than 240 network engineers and senior-level IT managers took part in the research.
