Network slicing

Definition

Network slicing is a method in telecommunications that allows multiple virtual networks to be created on top of a shared physical infrastructure, enabling the customization of network resources to meet specific service requirements. This approach enhances the efficiency and flexibility of network management, allowing operators to optimize performance based on varying demands from different applications and user types. By leveraging network slicing, providers can deliver tailored services, improve user experiences, and effectively support diverse use cases.
