Table - Acronyms and Terminologies
| Acronyms | Definition |
|---|---|
| 5G NF | 3GPP 5G Network Function |
| Bastion Host | The Bastion Host is a node that hosts general orchestration support for the site. The Bastion Node runs as a virtual machine on a Kubernetes Master Host. It is used to host the automation environment and run the install automation. The install automation provisions and configures all other hosts, nodes, and switches within the frame. After the installation process is completed, the Bastion Host continues to serve as the customer gateway to cluster operations and control. |
| BFG | Border Gateway Protocol |
| BIOS | Basic Input Output System |
| CCV | Custom Configurable Volumes |
| CLI | Command Line Interface |
| Cluster | A collection of hosts and nodes dedicated to providing a cloud native runtime environment for containerized services and applications. The cluster is comprised of the collection of Master and Worker Nodes and is managed by Kubernetes. |
| CNE | Oracle Communications Cloud Native Core, Cloud Native Environment |
| CNC Console | Oracle Communications Cloud Native Configuration Console |
| CNLB | Cloud Native Load Balancer |
| Computer or Machine | A computer is a machine or device that performs processes, calculations, and operations based on instructions provided by a software or hardware program. Machine and computer are equivalent and interchangeable. Therefore, a virtual machine or physical machine is equivalent to a virtual computer or physical computer. |
| Container | An encapsulated software service. All 5G applications and Operations, Administration, Maintenance (OAM) functions are delivered as containerized software. The purpose of the CNE is to host containerized software providing 5G Network Functions (NFs) and services. |
| CSI | Container Storage Interface |
| DB | Database |
| DBMS | Database Management System |
| DHCP(D) or DHCP | Dynamic Host Configuration Protocol |
| DNF | Dandified YUM |
| DNS | Domain Name Server |
| DNSSEC | Domain Name System Security Extensions |
| FQDN | Fully Qualified Domain name |
| GRUB | Grand Unified Bootloader |
| GUI | Graphical User Interface |
| HDD | Hard Disk Drive |
| Host | A host is a computer that is loaded with an Operating System (OS) and is accessible over a network. This includes physical or virtual machines. Though host and node have different meanings, they can often be confused. Therefore, in this document, the host refers to the role of the physical computer in the CNE solution, and Host OS refers to the operating system running on the physical computer. |
| HP | Hewlett Packard |
| HPE | Hewlett Packard Enterprise |
| HTTP | HyperText Transfer Protocol |
| Installer Bootstrap Host | As an early step in the site installation process, one of the hosts is minimally provisioned to act as an Installer Bootstrap Host. The Installer Bootstrap Host has a very short lifetime since its job is to provision a Bastion Host. The Bastion Host performs the remainder of the CNE installation. The Installer Bootstrap Host is also known as the Bootstrap Host. Later in the installation process, this Bootstrap Host (RMS1) is reprovisioned as a Kubernetes Master Host. |
| iLO | HPE Integrated Lights-Out Management System |
| IP | Internet Protocol, can be used as shorthand to refer to an IP layer 3 address. |
| IPv4 | Internet Protocol version 4 |
| IPv6 | Internet Protocol version 6 |
| ISO | International Organization for Standardization; generally used as shorthand to refer to an ISO 9660 optical disk file system image |
| KVM | Keyboard, Video, Mouse. This abbreviation is a homograph of another meaning for the same abbreviation. Where these are used within the document, the document will provide context to understand which one is being referenced. |
| KVM | Kernel Virtual Machine. This abbreviation is a homograph of another meaning for the same abbreviation. Where these are used within the document, the document will provide context to understand which one is being referenced. |
| K8s | Shorthand alias for Kubernetes |
| K8s Controller Node | Some nodes in the system such as RMS 1, 2, and 3 are dedicated to providing container management. These nodes are responsible for managing all of the containerized workloads that run on the Kubernetes Worker Nodes. |
| K8s Worker Node | Some nodes in the system such as the blade servers within the enclosure, are dedicated to hosting containerized software and providing the 5G application services. |
| LB | Load Balancer |
| LBVM | Load Balancer Virtual Machine |
| MAC | Media Access Control address |
| Management Host | The Management Host is a physical machine in the RMS frame that contains a special configuration to support hardware installation and configuration of other components within a frame. For CNE, there is one machine, RMS1, with dedicated connectivity to out of band (OOB) interfaces on the Top of Rack switches. The OOB interfaces provide the connectivity required to initialize ToR switches. When referring to a machine as a Management Host, the context is related to its OOB connections that are unique to the RMS1 configuration. |
| MBE | Minimal Bootstrapping Environment |
| MTU | Maximum Transmission Unit |
| NFS | Network File System |
| Node | In general use, a "node" is any system or device connected to a network. A "node" is usually a networking endpoint. In this document, a "node" refers to a service within the CNE, such as "Kubernetes Controller Node", which provides the Kubernetes etcd data and serves as a management entity for the cluster. |
