What role does software-defined networking (SDN) play in enabling network slicing ?
Network slicing is a key feature of 5G networks that allows operators to create multiple virtual networks on top of a shared physical infrastructure. SDN plays a crucial role in enabling network slicing by providing the necessary flexibility and programmability to manage and control the network resources. The SDN architecture consists of three main components: the data plane, the control plane, and the management plane. SDN enables network slicing by providing a centralized view of the network resources and allowing operators to dynamically allocate these resources to different slices based on their QoS requirements. Key benefits of SDN for network slicing include flexibility, programmability, centralized control, and resource optimization. Use cases for SDN in network slicing include mobile broadband, IoT, and enterprise networks.
