Technology creating multiple virtual networks on shared physical infrastructure.
Description
Network Slicing enables creation of multiple logical networks (slices) on a common physical infrastructure, each optimized for specific service requirements. Each slice can have different characteristics for latency, reliability, throughput, and security.
Slices are identified by S-NSSAI (Single Network Slice Selection Assistance Information) and can span the entire network from RAN to core. The network selects appropriate slice based on subscription and service requirements.
Purpose & Motivation
Network Slicing was introduced to:
- Support diverse 5G use cases on shared infrastructure (eMBB, URLLC, mMTC) - Enable service differentiation for enterprise customers - Provide resource isolation and guaranteed SLAs - Allow independent slice lifecycle management
Key Features
- ✓S-NSSAI identification
- ✓End-to-end slice isolation
- ✓Slice-specific QoS
- ✓NSSF for slice selection
- ✓RAN slicing support
- ✓Independent lifecycle management
