Software-defined networking (SDN) enhances network management by decoupling the network control layer from the hardware. This architecture allows centralized control and programmability through software applications, enabling more flexible and efficient network operations. With SDN, administrators can easily configure, manage, and optimize the network, responding quickly to changes in demand or security threats. It facilitates better resource allocation, reduces operational costs, and simplifies the deployment of new services. Additionally, SDN enhances network visibility, improving monitoring and performance analysis, which ultimately leads to a more robust and reliable network environment.
