A primary benefit of using a Software Defined Network (SDN) is centralized management and flexibility in network control. SDN allows network administrators to manage and configure the network through a centralized software-based controller, which abstracts the underlying hardware. This means that instead of configuring individual hardware devices separately, administrators can adjust network settings and policies from a single interface.

This centralized approach streamlines operations, reduces configuration errors, and allows for quicker adaptation to changing network conditions or requirements. Additionally, the flexibility of SDN enables dynamic adjustments to the network without the need for physical changes to the hardware, enhancing the network’s ability to evolve in response to business needs and application demands. This fundamental shift from hardware-dependent configurations to software-based management is what primarily distinguishes SDN from traditional networking models.

In contrast, reliance on hardware devices, protocol restrictions, and hardware management do not encapsulate the main advantages provided by SDN.
