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
...
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
- VNF Type- EPC CP, PGW DP, SGW DP, BNG DP etc. – where CP is Control Plane and DP is Data Plane
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
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
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
