5G Network Slice Manager

5G network slice lifecycle management and orchestration platform. Implements ETSI NFV MANO architecture for creating, monitoring, and managing network slices across eMBB, URLLC, and mMTC service types per 3GPP specifications.

Slice Types (3GPP TS 23.501)

Type	SST	Latency	Throughput	Reliability	Use Case
eMBB	1	10ms	100 Mbps DL / 50 Mbps UL	99.9%	Video, AR/VR
URLLC	2	1ms	10 Mbps	99.999%	Industrial IoT, autonomous vehicles
mMTC	3	100ms	100 kbps	99.9%	Smart city, sensors

Slice Lifecycle

Instantiating → Configuring → Active → Modifying → Terminating → Terminated
