ONAP ComponentLife Cycle PhaseEnhancements
PolicyDesign

Configuration Policies for Guaranteed, Burstable & Best Effort Cloud Infrastructure Resource Slices (this will apply to VMs/Containers also)

Placement Policies for Resource Slices

  • Higher (programmable) weight to Cloud Region which supports all three types of resource slices vs only two types of resource slices (Guaranteed/Best Effort)

Network Slice Allocation across several Clouds

  • Allocate a contiguous network slice for extreme mobile broadband (ref. 1) with a max. latency of 10ms
    • Maps to Burstable Resource Slice in the infrastructure with min./max. of CPU, Memory etc.

Aggregation Service

ONAP, as in R2, collects the statistics/alarms/events from workloads (VMs) and take any close loop control actions such as Heal a process, scale-out, restart etc.. In R3, infrastructure related statistics/alarms/events will be collected, generate actionable insights and take life cycle actions on the workloads.  Infrastructure statistics normally include performance counters, NIC counters, IPMI information on per physical server node basis.  To reduce the load on the ONAP, it is necessary that aggregated (summarized) information is sent to the ONAP from edge-clouds. 

As part of this activity, intention is to create aggregation micro-service that collects the data from physical nodes (over collected and other mechanisms), aggregate the information (time based aggregation, threshold based aggregation, silencing etc.,..) based on the configurable rules and export the aggregate data to DCAE.  This micro service can be instantiated by ONAP itself - one or more instances for edge-clouds at the ONAP-central itself using OOM, it could be instantiated at the edge-cloud using their own deployment tools or it could be deployed edge service providers at the regional site level.  

Impacted projects:

ONAP ComponentEnhancements
Multi-Cloud
  • Development activities:
    • Prometheus based monitoring & summation
    • Support for collected for statistics collection from NFVI nodes.
    • Support for VES agent to send the aggregate data to DCAE (Used when the aggregate service is instantiated outside of ONAP control)
    • Support for DMAAP agent to send the aggregate data to DCAE (Normally used if the aggregate service is instantiated at the ONAP-Central.
    • Provide ability to add new plugins (to collect statistics as well as to export aggregation information)
    • Provide ability to upload the recording and alert rules (on per edge-cloud basis or set of edge-clouds basis)
    • Ability to auto-cleanup of time series DB (based on size allocated for this micro-service)
  • Edge-Cloud registration time (as part of ESR)
    • Check whether registration data indicates whether the aggregation service to be brought up). If so, inform the aggregation micro service to authentication and listen for statistics from that edge-cloud.
  • Run time
    • Collects the information (support for both pull/push).
    • Apply rules
    • Generate alarms
    • Export them via VES or DMAPP or any other plugins in future.
AAI & ESR
  • Development activities
    • Enhancements to ESR to indicate whether aggregation service is required for this edge-cloud at the ONAP.
    • Enhancements to ESR to indicate Multi-Cloud for Multi-Cloud to listen for connections and statistics requests from the edge-clouds. Information such as CA cert to use to authenticate the remote party or any other UN/PWD method.
PORTALESR portal related changes to take information about the edge-cloud (CA Cert and UN/PWD information)
DCAE & DMAPPNone expected??
