5G network slicing is a feature of a cloud-native 5G network architecture that leverages the principles behind network functions virtualization (NFV) and software-defined networking (SDN), allowing for flexible, programmable converged networks wherein disparate services that would typically require parallel systems reside on a single infrastructure. In such an architecture, each network “slice” is an isolated, bespoke end-to-end network tailored to fulfill the requirements of a particular application.
Or you can take Ericsson’s definition: “Network slicing is the operators’ best answer on how to build and manage a network that meets and exceeds the emerging requirements from a wide range of users.”
