Many enterprises are unable to achieve business innovation because of aging networking environments. Enterprise network design and architectures have remained largely unchanged for more than a decade. While applications and systems have evolved to meet the demands of a world where real-time communications, rich-media, and mobility are the norm, the underlying network infrastructure has not kept pace. Read this paper if you are interested in making your enterprise network more agile and adaptable to changing business needs. This paper describes the benefits of software-defined networking (SDN) enabled by OpenFlow technology. SDN, enabled by OpenFlow, holds the promise of breaking the logjam in network agility by eliminating legacy human middleware and paving the way for innovation.
