- Guaranteed Resource Slice (hard isolation) for various infra Resources (CPU/Memory/Network)
- Max (limit), Min (request) are the same; resource guarantee is "Max"
- Maps to 5G Applications such as Connected Car which fall in the category of ultra-reliable machine-type communications (ref. 1)
- Burstable Resource Slice (soft isolation) for various infra Resources
- Min (request) <= Max (limit); resource guarantee is "Min"
- Maps to Burstable Network Slice such > 1Gbps broadband which fall in the category of extreme mobile broadband (ref. 1)
- Best Effort Resource Slice (no isolation) for various infra Resources
- No Min (request) ; resource guarantee is "None"
- Maps to 5G Applications such as IoT which fall in the category of massive machine-type communications (ref. 1)
