Scoring criteria of the Infrastructure Maturity Assessment technological capabilities on the 4-step experience scale.
| Technological capabilities | Level 0 | Level 1 | Level 2 | Level 3 |
| Virtualization | Virtual segmentation of campus infrastructure is based on static configuration. | Macro–virtual segmentation of campus infrastructure is based on VLANa trunking protocol propagation and VRFb. | Micro–virtual segmentation of campus infrastructure is based on VxLANc. | Access controlled, policy-based microsegmentation of campus infrastructure is based on VxLAN. |
| End of support status | End of support status applies to ≤5% of core and distribution layer technologies and ≤30% of access layer technologies. | End of support status applies to ≤5% of core and distribution layer technologies and ≤20% of access layer technologies. | End of support status applies to ≤3% of core and distribution layer technologies and ≤10% of access layer technologies. | End of support Status applies to ≤3% of core, distribution, and access layer technologies. |
| Wired device grade | Approximately ≤70% of switches and routers are enterprise grade. | N/Ad | Approximately 71% to 97% of switches and routers are enterprise grade. | Approximately >98% of switches and routers are enterprise grade. |
| QoSe | Fragmented QoS within the health care entity campus has been implemented. Trust boundaries are well defined. | End-to-end QoS has been implemented within the health care entity campus. Trust boundaries are well defined. | End-to-end QoS has been implemented within the health care entity campus and across the WANf. Trust boundaries are well defined. | SDNg controllers have been implemented and are used to provide business applications and dynamic end-to-end QoS within the health care entity campus and across the WAN. Trust boundaries are well defined. |
