-Definition of terms
-===================
-
-Different SDOs and communities use different terminology related to
-NFV/Cloud/SDN. This list tries to define an OPNFV terminology,
-mapping/translating the OPNFV terms to terminology used in other contexts.
-
-.. glossary::
-
- Administrator
- Administrator of the system, e.g. OAM in Telco context.
-
- Consumer
- User-side Manager; consumer of the interfaces produced by the VIM; VNFM,
- NFVO, or Orchestrator in ETSI NFV [NFV003]_ terminology.
-
- NFV
- Network Function Virtualization
-
- NFVI
- Network Function Virtualization Infrastructure; totality of all hardware
- and software components which build up the environment in which VNFs are
- deployed.
-
- NFVO
- Network Functions Virtualization Orchestrator; functional block that
- manages the Network Service (NS) lifecycle and coordinates the management
- of NS lifecycle, VNF lifecycle (supported by the VNFM) and NFVI resources
- (supported by the VIM) to ensure an optimized allocation of the necessary
- resources and connectivity.
-
- Physical resource
- Actual resources in NFVI; not visible to Consumer.
-
- Resource zone
- A set of NFVI hardware and software resources logically grouped
- according to physical isolation and redundancy capabilities or to
- certain administrative policies for the NFVI [NFVIFA010]_
-
- VIM
- Virtualized Infrastructure Manager; functional block that is responsible
- for controlling and managing the NFVI compute, storage and network
- resources, usually within one operator's Infrastructure Domain, e.g. NFVI
- Point of Presence (NFVI-PoP).
-
- Virtual Machine (VM)
- Virtualized computation environment that behaves very much like a physical
- computer/server.
-
- Virtual network
- Virtual network routes information among the network interfaces of VM
- instances and physical network interfaces, providing the necessary
- connectivity.
-
- Virtual resource
- A Virtual Machine (VM), a virtual network, or virtualized storage; Offered
- resources to "Consumer" as result of infrastructure virtualization;
- visible to Consumer.
-
- Virtual Storage
- Virtualized non-volatile storage allocated to a VM.
-
- VNF
- Virtualized Network Function. Implementation of an Network Function that
- can be deployed on a Network Function Virtualization Infrastructure (NFVI).
-
- VNFM
- Virtualized Network Function Manager; functional block that is responsible
- for the lifecycle management of VNF.
