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 Network Function Virtualization
13 Network Function Virtualization Infrastructure; totality of all hardware
14 and software components which build up the environment in which VNFs are
18 Virtualized Network Function. Implementation of an Network Function that
19 can be deployed on a Network Function Virtualization Infrastructure (NFVI).
22 Virtualized Infrastructure Manager; functional block that is responsible
23 for controlling and managing the NFVI compute, storage and network
24 resources, usually within one operator's Infrastructure Domain, e.g. NFVI
25 Point of Presence (NFVI-PoP).
28 Network Functions Virtualization Orchestrator; functional block that
29 manages the Network Service (NS) lifecycle and coordinates the management
30 of NS lifecycle, VNF lifecycle (supported by the VNFM) and NFVI resources
31 (supported by the VIM) to ensure an optimized allocation of the necessary
32 resources and connectivity.
35 Virtualized Network Function Manager; functional block that is responsible
36 for the lifecycle management of VNF.
39 User-side Manager; consumer of the interfaces produced by the VIM; VNFM,
40 NFVO, or Orchestrator in ETSI NFV [7] terminology.
43 Administrator of the system, e.g. OAM in Telco context.
46 Virtualized computation environment that behaves very much like a physical
50 Virtualized non-volatile storage allocated to a VM.
53 Virtual network routes information among the network interfaces of VM
54 instances and physical network interfaces, providing the necessary
58 Actual resources in NFVI; not visible to Consumer.
61 A Virtual Machine (VM), a virtual network, or virtualized storage; Offered
62 resources to "Consumer" as result of infrastructure virtualization; visible
