SDN (Software-Defined Networking)

Software-Defined Networking (SDN) is a technology that separates the control part of a network from the physical hardware, allowing centralized management. Think of it as a control tower that directs and manages network traffic automatically, rather than each device making decisions independently. This centralized controller makes networks more flexible, easier to configure, and faster to adapt to changing needs. SDN enables administrators to quickly set policies, optimize performance, and improve security across the entire network through software, rather than manually configuring each device. It streamlines network management and enhances overall efficiency.
