The diverse use cases requirements and strict expectations of latency on shared infrastructure, from future networks, calls for networking paradigms that can provide efficiency and flexibility. Network slicing is a network paradigm introduced with 5G, which is a key in realizing diverse service requirements and meeting expectations of future 6G networks. A Network Digital Twin (NDT) model can benefit the management and orchestration of network slicing life cycle and provide a clear visual representation of the physical entities of a network slicing model while enabling experimenting with different resource allocation schemes without actually affecting the physical network. A NDT bridges the gap between physical world and digital world by having constant bi-directional communication. Hence, in this article we make a case for NDT as a key enabler of network slicing in 6G network while integrating Artificial Intelligence (AI) based network slicing strategy to enable end-to-end (E2E) Quality of Service provisioning.
