Aggregate Representation Class Attributes

...

• 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
