Resource Cluster Group Usage Example

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

Resource Cluster A - “RCA” - hosts with standard NICs

Resource Cluster B - “RCB” - hosts with IPSec offload NICs

Resource Cluster Group A - “RCGA” - “RCA” and “RCB”

Resource Cluster Group B - “RCGB” - “RCB”

Resource Slice A - “RSA” - logical slice in “RCGA”

Resource Slice B- “RSB”- logical slice in “RCGB”

Resource Slice C- “RSC”- logical slice in “RCGB”

Realizing Minimum guarantees

  • Sum of minimum guarantees of resource slices cannot exceed the total capacity of the resource clusters they belong to

Placement Policy 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

R1 vCPE use case – Illustrative Sequence Diagrams (https://wiki.onap.org/display/DW/Residential+Broadband+vCPE+Drafts+for+discussion?preview=%2F10783327%2F16005563%2FvCPE+Use+Case+-+Customer+Service+Instantiation+-+171103.pptx)

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 OF

  • 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 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

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

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
