Optimizing Network Management through Software-Defined Networking in Computer Communications

Software-Defined Networking (SDN) has emerged as a transformative model in digital connectivity, enabling flexible and programmable network administration. This dissertation explores the foundational principles, architectural elements, and key technologies of SDN. It investigates the advantages of separating the control plane from the data plane, providing centralized network oversight, and enabling dynamic network provisioning. The dissertation also delves into SDN's potential to enhance network effectiveness, security, and scalability. Furthermore, it examines the challenges and open research issues in the practical execution and deployment of SDN. By analyzing case studies and real-world implementations, this dissertation aims to provide valuable insights into the role of SDN in reshaping digital connectivity and paving the way for future networking innovations.
