Software Defined Networking & OpenFlow

Learn about the concept of Software Defined Networking (SDN) and OpenFlow, which allow for greater flexibility, innovation, and cost savings in network infrastructure. Discover how SDN eliminates the limitations of traditional networking by separating control and data planes, enabling network programmability.
