    Table 1 explains glossary terms that are new for the Cloud CPE Centralized Deployment Model.

    Table 1: Glossary for Cloud CPE Centralized Deployment Model

    Acronym

    Term

    Meaning

    HOT

    Heat Orchestration Template

    YAML file that provides that provides the infrastructure for a cloud application.

    IPMI

    Intelligent Platform Management Interface

    Standard interface through which you can manage industry-standard servers over a network, rather than though their individual CPUs, OS, and firmware. IPMI enables consistent management of multiple servers from different vendors, and leads to efficiencies in IT operations, potentially through automation.

    Microservices architecture

    Distributed, non-hierarchical framework for a software application in which multiple software modules—microservices—interact to perform the functions of the application. Each microservice operates independently to implement a set of focused, related functions. The modular approach enables developers to make targeted updates to the software and facilitates a continuous software delivery model.

    NFV MANO

    NFV management and orchestration

    Optimization of network performance through automated coordination of compute, storage and networking resources, using data models based on network services. NFV MANO is performed by the VIM, and VNFM. Also a working group in the European Telecommunications Standards Institute (ETSI). See also VIM, VNFM.

    network function

    In NFV, a component that has well-defined interfaces and provides a specific networking capability in a well-defined way. A network function may be implemented by a physical networking device or a virtual application. See also PNF, VNF.

    NFVI

    network functions virtualization infrastructure

    In NFV, all hardware and software components used to create the environment in which VNFs can be implemented. See also VNF.

    PNF

    physical network functions

    In NFV, a network function that is provided by a physical networking device, such as a router or switch. See also network function, VNF.

    service chain, service chaining

    Use of multiple network services on a connection between two locations in a virtual network. For example, a server can connect to the Internet through firewall and NAT services. In a dynamic service chain, additional network services can be added to an active chain. Service chaining is analogous to a series of network devices—such as one security device that is a firewall and another device that performs NAT—between two locations in a physical network.

    VIM

    virtualized infrastructure manager

    In NFV, the software component that manages the compute, storage, and network resources.

    VNF

    virtualized network function

    In NFV, a network function that is provided by a virtual application. See also network function, PNF.

    VNF instance

    Active implementation of a VNF that the VNF manager has created, made operational, and is controlling through MANO.

    VNFM

    VNF manager

    In NFV, the software component that manages the lifecycle of VNF instances. See also VNF, VNF instance.
