ICN project injects the user data in each server regarding network configuration, remote command execution using ssh and maintain a common secure mechanism for all provisioning the servers. Each local controller maintains IP address management for that edge location. For more information refer - Metal3 Baremetal Operator in ICN stack
BPA Operator: Itohan Ukponmwan ramamani yeleswarapu
ICN uses the BPA operator to install KUD. It can install KUD either on Baremetal hosts or on Virtual Machines. The BPA operator is also used to install software on the machines after KUD has been installed successfully

BPA Rest Agent: Enyinna Ochulor
Provides a straightforward RESTful API that exposes resources: Binary Images, Container Images, and OS Images. This is accomplished by using MinIO for object storage and Mongodb for metadata.

Kubernetes deployment (KUD) is a project that uses Kubespray to bring up a Kubernetes deployment and some addons on a provisioned machine. As it already part of ONAP it can be effectively reused to deploy the K8s App components(as shown in fig. II), NFV Specific components and NFVi SDN controller in the edge cluster. In R2 release KuD will be used to deploy the K8s addon such as Virlet, OVN, NFD, and Intel device plugins such as SRIOV and QAT in the edge location(as shown in figure I). In R3 release, KuD will be evolved as "ICN Operator" to install all K8s addons. For more information on the architecture of KuD please find the information here.
ONAP4K8s: Kuralamudhan Ramakrishnan
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.
SDWAN:
SDWAN 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 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 functionalities, detail information can be found at: SDWAN Module Design
