Software-defined networking (SDN) is a network architecture that uses software to manage network functions, offering increased flexibility and ease of management.

It allows centralized control of network resources, regardless of hardware manufacturer, enabling faster application deployment and reduced operational costs.

Key benefits include automation, improved security through a central control point, and simplified network provisioning, extending to cloud environments. SDN's programmability and remote management capabilities are expected to become standard in future networks.
