ONAP is used as Service orchestration in ICN BP. A lightweight golang version of ONAP is developed as part of Multicloud-k8s project in ONAP community. ICN BP developed containerized KUD multi-cluster to install the onap4k8s as a plugin in any cluster provisioned by BPA operator. ONAP4k8s installed EdgeX Foundry Workload, vFW application to install in any edge location.

SDEWAN:
SDWAN SDEWAN CNF module is worked as a software-defined router which can be used to define the rules when connecting to the external internet. It is implemented as CNF instead of VNF for better performance and effective deployment, and leverage located in each edge location and central hub k8s cluster to manage central-edge and edge-edge communication. It's functionality is realized via CNF (Containerized Network Function) and deployed by K8s, it is based on OpenWRT (an open-source project based on Linux, and used on embedded devices to route network traffic) and mwan3 package (for wan interfaces management) to implement its functionalitiesleverages Linux kernel functionality for packet processings to support network functionalities such as multiple wan link support (mwan3), firewall/SNAT/DNAT (fw3) , IPSec (strongswan) etc. Restful APIs are provided for configuration, detail information can be found at: SDEWAN CNF
SDEWAN Configure Agent module is worked as K8s controller located in each edge location and central hub k8s cluster to support configuration of SDEWAN CNF functionalities (e.g. mwan3, firwall, SNAT, DNAT, IPSec etc.) and monitor SDEWAN CNF status. It exposes CRDs to support configuration via K8s API server for unified authentication and authorization, detail information can be found at: ICN - SDEWAN Sdewan config Agent
Cloud Storage:
Cloud Storage which used by BPA Rest Agent to provide storage service for image objects with binary, container and operating system. There are 2 solutions, MinIO and GridFS, with the consideration of Cloud native and Data reliability, we propose to use MinIO, which is CNCF project for object storage and compatible with Amazon S3 API, and provide language plugins for client application, it is also easy to deploy in Kubernetes and flexible scale-out. MinIO also provide storage service for HTTP Server. Since MinIO need export volume in bootstrap, local-storage is a simple solution but lack of reliability for the data safety, we will switch to reliability volume provided by Ceph CSI RBD in next release.
