|Business Registration||Registers all stakeholders that participate in NGPaaS (VSPs, Vendors, etc.). It also includes the resolution of access and execution rights.|
|BaaS||A customisable catalogue from which to order service or platform workloads.|
|BSS/OSS||Responsible for inventory registration, global supervision, and deployment of services and platforms on their execution environments. In our prototype, the BSS/OSS role  is fulfilled by the RDCL 3D tool.|
|Dev-for-Operations||An environment to support the innovative NGPaaS Dev-for-Operations model—an evolution of the existing DevOps model to facilitate new types of interaction and development methods between multiple stakeholders. This environment is where staging and development are performed to bring new PaaS or service components into NGPaaS .|
|PaaS||PaaS components are deployed on the available (declared) infrastructure. These PaaS components form the framework to manage the VNFs included in the requested services. More than one PaaS instances can be active and managed at the same time by the OSS/BSS.|
|IaaS||This layer relates to the cloud infrastructure available to the NGPaaS operator.|
|Infrastructure registration||A generic provisioning process to support the broad spectrum of available infrastructure technologies. According to the use-case and the required services, the appropriate infrastructure nodes are leased and registered in the OSS.|
|PaaS orchestration||Refers to the deployment of selected PaaS components on the appropriate IaaS. The PaaS could be Kubernetes, CORD, or any other platform. The PaaS components can be aggregated flexibly and modelled as RFBs. This capability could not be implemented using ETSI MANO, which is focused only on VNFs and assumes the platform is already deployed.|
|Service orchestration||A service is provided by deploying VNFs as sets of RFBs. The target execution environment of each VNF is included in the metadata of the related RFBs, which also specify the runtime aspect: VM, container, Unikernel, FPGA Bitstream, etc. The execution environment of a service component is a pre-deployed PaaS which supports the runtime aspects of the RFB.|
|Onboarding new components||The design rule in NGPaaS is “everything is an RFB” (VNF, ancillary services like orchestration, SDN controller, etc.). Therefore, all the components could be updated, upgraded, swapped, etc. This can be done through the usage of the Dev-for-Operations processes.|
|Pre-deployment Configuration RFBs||Responsible for configuring the target infrastructure node for the subsequent deployment of the CORD platform. An example is the cloning of remote source code repositories so that CORD can be later built from.|
|Deployment RFBs||These are the core RFBs, that when executed will provide with a functional CORD deployment on the infrastructure node. The majority of them are tied to the deployment of groups of containers, through the Helm tool. An example is the deployment of the XOS orchestrator or the ONOS SDNC.|
|Post-deployment configuration RFBs||These configure a CORD deployment for a specific use case or resolve possible issues that might have risen during the deployment of the CORD platform. An example is the registration of the CORD compute node to the ONOS SDNC.|
|RFB Name||RFB Role|
|k8s||Deploys Kubernetes, which manages all Docker containers comprising CORD.|
|Ingress||Deploys Ingress, a component related to Kubernetes which facilitates external access to services running in the cluster.|
|rabbitMq||Deploys RabbitMQ, the message broker used in OpenStack|
|Ceph||A set of RFBs that deploy ceph, the distributed storage component of OpenStack|
|marriaDB||Deploys marriaDB, the database for OpenStack|
|memCached||Deploys memcached, the distributed memory caching system for OpenStack|
|Heat||Deploys Heat, the OpenStack orchestrator.|
|Glance||Deploys Glance, the OpenStack image registry.|
|Keystone||Deploys Keystone, the OpenStack identity service.|
|openvSwitch||Deploys an OpenvSwitch, instance that connects all OpenStack VMs.|
|Nova||Deploys Nova, the computing service of OpenStack.|
|Neutron||Deploys Neutron, the networking service of OpenStack. In CORD Neutron is responsible for creating the networks connecting the different VMs.|
|openstackChart||Deploys the OpenStack service synchronizer of CORD.|
|addressManagerChart||Deploys a set of components, which enable public connectivity for VNFs.|
|onosChart||Deploys the ONOS synchronizer in CORD.|
|xosChart||Deploys the XOS synchronizer in CORD.|
|ngpaasserviceChart||Deploys the ngpaasService synchronizer. It also onboards the service model.|
|localVolumeChart||Deploys the persistent storage component of CORD.|
|clientSetup||Deploys the OpenStack client (Command Line Interface).|
|Libvirt||Deploys libvirt, the virtualisation service to be used by OpenStack|
|Docker||Deploys Docker on the target node.|
|dockerImageDownload||Downloads all CORD related Docker Images|
