According to the Dell'Oro Group, the software defined networking (SDN) market is forecast to grow more than 65% in 2014, vs. 2013. With architectures ratified and production deployments under way, network security appliances and Ethernet switches are expected to continue to comprise the majority of SDN's impact, with SDN gaining a foothold outside of the major cloud providers. The research house expects an evolution toward 10 GigE in the enterprise and 25 GigE in the cloud.
