STOCKHOLM, April 2, 2013 /PRNewswire/ -- Tail-f Systems today announced the findings of its 2013 Software Defined Networking Survey, which shows nearly nine of ten organizations are at least discussing SDN. In fact, SDN was judged by more than 200 large companies in North America to be the single most important technology initiative, eclipsing cloud, virtualization and mobility. Despite the high interest, however, the survey reveals that most companies are still fairly confused as to exactly what SDN is. "Large organizations are crying out for a simpler way to meet application and service SLAs," says Hakan Millroth, CTO for Tail-f. "They are clearly captivated by SDN's potential to improve network automation and simplify the process of provisioning and controlling applications and network services." Interest in SDN Is High The survey showed that SDN is a hot topic within IT organizations. When presented with a list of five different IT initiatives, 87 percent of respondents chose SDN as important, surpassing virtualization, mobility and even cloud. According to the survey, 9 out of 10 (89 percent) respondents are discussing SDN. The drivers mentioned by respondents focused on applications or services – primarily that they are increasingly important, there are more of them, and they are rolled out at a faster pace than ever before. Also on their minds was interest in automating the network, and the prevalence of virtualization. Confusion about SDN Still Reigns Given the high interest in SDN, organizations are still confused about what SDN is. In fact, most (92 percent) rate their understanding of SDN as pretty good or even complete; yet only about half (51 percent) chose a correct definition of SDN.

In light of the fact that most large enterprise network environments contain multiple vendors' devices and solutions, respondents are looking for solutions that can fit their network model easily without added infrastructure costs.
