Software Defined Networking, or SDN, is an innovative approach to network architecture that allows the network to be intelligently and centrally directed through software applications. In essence, the behavior of the network is controlled by software that lives beyond the networking devices providing physical connectivity. SDN’s relevance is underscored by the monumental growth in multimedia content, increasing mobile usage, and intense competition ultimately pressuring businesses to cut costs.
SDN: A Necessary Technology for Today’s World
Many global technology companies are turning to SDN technology to keep pace with rapid changes and demands within the industry. This innovative technology offers a revolution in network design and operations. By opening up traditionally closed network platforms and implementing a unified SDN control layer, operators have the ability to manage the entire network and its devices consistently.
This comprehensive management allows for optimum use of resources. Furthermore, by separating the hardware from the software, operators are free to introduce innovative, differentiated new services rapidly, without the constraints of closed and proprietary platforms.
SDN and the New Era of Openness
SDN architectures are paving the way for a new era of openness—promoting multi-vendor interoperability. Efficient network management via SDN boosts the performance of Big Data applications. It facilitates big data acquisition, transmission, storage, and processing. Moreover, SDN also benefits from big data, especially in terms of traffic engineering and countering security attacks.

Challenges and Concerns Surrounding SDN
However, the transition to SDN architecture may prove challenging for many small and mid-range organizations. This could potentially lead to a competitive advantage for tech giants, thereby exacerbating global technological inequality.
Another issue that has drawn attention is that of data privacy. In a world where data protection debates are prevalent, SDN too will inevitably be drawn into these discussions, further underscoring the need for robust security measures and responsible handling of data.
