Network slicing is a technique for dividing a multi-domain infrastructure into numerous logical and virtualized networks. Mobile Network Operators (MNOs) can quickly develop network slices that support a certain application, service, group of users, or network using Software-Defined Networking (SDN), Network Functions Virtualization (NFV), orchestration, analytics, and automation. Network slices can be distributed across numerous operators and cover multiple network domains, including access, core, and transport.
Network slicing is the greatest solution for operators to construct and operate a network that meets and exceeds the needs of a diverse set of users. Transforming a sliced network into a group of logical networks on top of a shared infrastructure is the way to go. Each logical network is built to satisfy a specific business need and includes all of the necessary network resources that are configured and connected end-to-end.
The network slice is a logically segregated, self-contained, independent, and secure portion of the network that targets distinct services with varying speed, latency, and reliability needs. For a critical IoT use case, low latency, high bandwidth, and ultra-reliability are desirable, while higher latency and lower bandwidth are undesirable.
