Service Security Policy
Leverage Smart NICs to program security policies to deliver performance & scalability
Service Operational Policy
Leverage Host and Resource Cluster near-real-time resource metrics and real-time faults & alerts to substantially improve closed loop remediation response time
Service Placement Policy
Leverage Resource Cluster near-real-time allocated resource capacity and metrics/faults/alerts to substantially improve dynamic workload placement/scheduling across cloud regions
These can be represented as additional soft constraints in the placement/scheduling minimize/maximize objective function

A – Usage Examples
Resource Cluster Group Usage Example
...
VNF Type “EPC CP” uses “RSA”
NIC offloads are immaterial to EPC CP; EPC CP can use “RCA” and “RCB”
VNF Type “PGW DP” uses “RSB”
IPSec offload in NIC is a must for PGW DP performance reasons
VNF Type Examples
Control Plane (CP) – MME, 5G CU-CP
Data Plane (DP) or User Plane (UP) - PGW, SGW, BNG, 5G CU-UP
VNF Type maps to Resource Cluster Group Class (a Resource Cluster Group could have one or more Resource Clusters)
Multi Cloud Mapping of Resource Cluster Group
<Host Aggregate> in OpenStack; <Host Aggregate, Cluster> in VMware integrated OpenStack
vCPE Optimization Policy Example using Aggregate Objects
...
Constraints used by Optimization Framework (OFOOF)
VBNG location is fixed based on subscriber
VG MUX to VBNG Data Center connectivity latency cannot exceed certain value
Optimization Policy used by OFOOF
Choose optimized multi cloud instance for the placement of VG MUX for a given subscriber based on the above
Information/Data model Standardization Example
VNF Mapping to Infrastructure
In this example, each VNF maps to a Resource Slice in the infrastructureVNF Type- EPC CP, PGW DP, SGW DP, BNG DP etc. – where CP is Control Plane and DP is Data PlaneVNF Type maps to Resource Cluster Group Class (a Resource Cluster Group could have one or more Resource Clusters)
Multi Cloud Mapping of Resource Cluster GroupSlice
<Host Aggregate> in OpenStack; <Host Aggregate, Cluster> in VMware integrated OpenStack<Project> in OpenStack and VMware Integrated OpenStack; <Tenant> in Azure
Multi Cloud inputs used by OOF
Near-real-time stats per <Resource Slice, Resource Cluster Group> at scale using asynchronous push model using DMaaP
5G Optimization Policy Example using Aggregate Objects
R3 5G use case – Definition, Creation & Management of Network Slices; Optimization of the Deployed Network & Slices
Constraints used by Optimization Framework (OOF)
5G CU-UP location is fixed based on group of subscribers
5G CU-CP to 5G CU-UP Data Center connectivity latency cannot exceed certain value
Optimization Policy used by OOF
Choose optimized multi cloud instance for the placement of 5G CU CP for a group of subscribers based on the above
VNF Mapping to Infrastructure
In this example, each VNF maps to a Resource Slice in the infrastructure
Multi Cloud Mapping of Resource Slice
<Project> in OpenStack and VMware Integrated OpenStack; <Tenant> in Azure
- For the 5G CU-UP Data Plane VNF type, each VNF maps to a specific "Physical DC Endpoint" in a "Cloud Region"
Multi Cloud inputs used by OFOOF
Near-real-time stats per <Tenant<Resource Slice, Resource Cluster Group> at scale using asynchronous push model using DMaaP
