Introduction

The ICN blueprint family intends to address deployment of workloads in a large number of edges and also in public clouds using K8S as resource orchestrator in each site and ONAP-K8S EMCO as service level orchestrator (across sites).  ICN also intends to integrate infrastructure orchestration which is needed to bring up a site using bare-metal servers. Infrastructure orchestration, which is the focus of this page, needs to ensure that the infrastructure software required on edge servers is installed on a per-site basis, but controlled from a central dashboard.  Infrastructure orchestration is expected to do the following:

...

The user experience needs to be as simple as possible and even a novice user should be able to set up a site.

Use Cases

1. SDEWAN Controller with Open source based SDWAN CNF and IPSEC tunnelling between Edge DistributionsOpenness Edge deployments in ONAPSDEWAN HUB to establish IPSEC tunneling between Edge Distributions with Service Function Chaining(SFC)
2. Composite vFirewall to show case Telco, Cable Use cases using EMCO(Edge Multi-Cluster Orchestration)

Where on the Edge

Nowadays best efforts are put to keep the Cloud native control plane close to workload to reduce latency, increase performance, and fault tolerance. A single orchestration engine to be lightweight and maintain the resources in a cluster of compute node, Where the customer can deploy multiple Network Functions, such as VNF, CNF, Micro service, Function as a service (FaaS), and also scale the orchestration infrastructure depending upon the customer demand.

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  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.

EMCO <Finished so far>

One of the Kubernetes clusters with high availability, which is provisioned and configured by KUD will be used to deploy ONAP on K8s. ICN family uses ONAP Operations Manager(OOM) to deploy ONAP installation. OOM provides a set of helm chart to be used to install ONAP on a K8s cluster. ICN family will create OOM installation and automate the ONAP installation once a Kubernetes cluster is configured by  KUD
