NSI
Network Slice Instance
Complete set of instantiated Network Functions and dedicated cloud resources delivering a specific network slice.
Technical Explanation
An NSI is the physical and virtual realization of a network slice. It comprises dedicated or shared RAN resources (PRB reservations), virtualized 5GC core NFs (dedicated SMFs and UPFs), and configured transport tunnels, delivering end-to-end SLA isolation.
Key Functions
- Instantiated set of virtualized and containerized 5GC Network Functions
- Coupled with dedicated transport tunnels and radio resource reservations
- Delivers end-to-end service isolation for enterprise and industrial SLAs
