1 **Definition of terms**
3 Different SDOs and communities use different terminology related to
4 NFV/Cloud/SDN. This list tries to define an OPNFV terminology,
5 mapping/translating the OPNFV terms to terminology used in other contexts.
10 Administrator of the system, e.g. OAM in Telco context.
13 User-side Manager; consumer of the interfaces produced by the VIM; VNFM,
14 NFVO, or Orchestrator in ETSI NFV [NFV003]_ terminology.
17 Network Function Virtualization
20 Network Function Virtualization Infrastructure; totality of all hardware
21 and software components which build up the environment in which VNFs are
25 Network Functions Virtualization Orchestrator; functional block that
26 manages the Network Service (NS) lifecycle and coordinates the management
27 of NS lifecycle, VNF lifecycle (supported by the VNFM) and NFVI resources
28 (supported by the VIM) to ensure an optimized allocation of the necessary
29 resources and connectivity.
32 Actual resources in NFVI; not visible to Consumer.
35 Virtualized Infrastructure Manager; functional block that is responsible
36 for controlling and managing the NFVI compute, storage and network
37 resources, usually within one operator's Infrastructure Domain, e.g. NFVI
38 Point of Presence (NFVI-PoP).
41 Virtualized computation environment that behaves very much like a physical
45 Virtual network routes information among the network interfaces of VM
46 instances and physical network interfaces, providing the necessary
50 A Virtual Machine (VM), a virtual network, or virtualized storage; Offered
51 resources to "Consumer" as result of infrastructure virtualization; visible
55 Virtualized non-volatile storage allocated to a VM.
58 Virtualized Network Function. Implementation of an Network Function that
59 can be deployed on a Network Function Virtualization Infrastructure (NFVI).
62 Virtualized Network Function Manager; functional block that is responsible
63 for the lifecycle management of VNF.
