ONAP will be the Service Orchestration Engine in ICN family and is responsible for the VNF life cycle management, tenant management and Tenant resource quota allocation and managing Resource Orchestration engine(ROE) to schedule VNF workloads with Multi-site scheduler awareness and Hardware Platform abstraction(HPA). Required an Akraino dashboard that sits on the top of ONAP to deploy the VNFs
Kubernetes Block and Modules:
...
SDN Controller components: This block is responsible for managing SDN controller and to provide additional features such as Service Function chaining(SFC) and Network Route manager.
Apps/ Use cases:
- SDWAN usecase
- Distributed Analytics as a Service
- EdgeXFoundry use case
- VR 360 streaming
ICN Infrastructure layout:
...
- Use Clusterctl command to create the cluster for the cluster-api-provider-baremetal provider. For this step, we required KuD to provide a cluster and run the machine controller and cluster controller
- Users Machine CRD and Cluster CRD in configured to instated 4 clusters as #0 - #3, #1, #2, #3
- Automation script for OOM deployment is trigged to deploy ONAP on cluster #0
- KuD addons script in trigger in all edge location to deploy K8s App components, NFV Specific and NFVi SDN controller
- Subscriber or Operator requires to deploy the VNF workload such as SDWAN in Service Orchestration
- ONAP should place the workload in the edge location based on MultMulti-site scheduling and K8s HPA

| Release | Block | Components | Identified Gaps | Initial thought |
|---|---|---|---|---|
R2 | ZTP | Cluster-API | The cluster upgrade yet to be support | The definition of "cluster upgrade" and expected behaviour should be documented here. For example cluster upgrade could be kubelet version upgrade. |
| No node repair mechanism | Node logs such kubelet logs should be enable in the automation script | |||
| No Multi-Master support | Required to confirm from engineers | |||
| KuD | Virtlet , Multus, NFD & Istio | Installation script are in ansible and static. Required to be in daemonset | ||
| Virtlet & Intel Device plugin | Have to check with Virtlet support with device plugin framework | |||
| ONAP | OOM automation | Portal chart is deployed with loadbalancer with floating IP address | ||
| Dashboard | Monitoring tool to check the deployment across the multi site and show the metrics/statistics details to the operator | |||
| R3 | APP use cases | SDWAN | OpenWRT is potential candidate to configured SDWAN use case. Required more information on it |
