NSMF
Network Slice Management Function
Management plane function managing end-to-end lifecycle, orchestration, and scaling of Network Slice Instances.
Technical Explanation
The NSMF receives slice requirements from the CSMF and decomposes them into domain-specific requirements for RAN, Core, and Transport. It orchestrates slice instantiation, continuous SLA performance monitoring, dynamic auto-scaling, and eventual slice decommissioning across multi-cloud infrastructure.
Key Functions
- Orchestrates end-to-end lifecycle of Network Slice Instances (NSIs)
- Decomposes slice requirements into RAN, Core, and Transport subnets
- Monitors slice SLAs in real-time and triggers dynamic resource scaling
