Software-defined networking (SDN) revolutionizes network management by separating the network control plane from the data plane. This allows for centralized control, enabling administrators to manage network traffic dynamically through software rather than hardware. With SDN, organizations can achieve greater flexibility and automation in configuring networks, improving their ability to respond to changing demands. By implementing SDN, IT departments can streamline operations, enhance security measures, and reduce costs associated with traditional network hardware. Overall, SDN increases agility and innovation within network management, aligning it closely with business requirements and goals.
