+**Definition of terms**
+
+Different standards developing organizations and communities use different
+terminology related to Network Function Virtualization, Cloud Computing, and
+Software Defined Networking. This list defines the terminology in the contexts
+of this document.
+
+
+.. glossary::
+
+ API
+ Application Programming Interface.
+
+ Cloud Computing
+ A model that enables access to a shared pool of configurable computing
+ resources, such as networks, servers, storage, applications, and
+ services, that can be rapidly provisioned and released with minimal
+ management effort or service provider interaction.
+
+ Edge Computing
+ Edge computing pushes applications, data and computing power (services)
+ away from centralized points to the logical extremes of a network.
+
+ Instance
+ Refers in OpenStack terminology to a running VM, or a VM in a known
+ state such as suspended, that can be used like a hardware server.
+
+ 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.
+
+ SDN
+ Software-Defined Networking. Emerging architecture that decouples the
+ network control and forwarding functions, enabling the network control
+ to become directly programmable and the underlying infrastructure to be
+ abstracted for applications and network services.
+
+ Server
+ Computer that provides explicit services to the client software running
+ on that system, often managing a variety of computer operations. In
+ OpenStack terminology, a server is a VM instance.
+
+ vForwarder
+ vForwarder is used as generic and vendor neutral term for a software
+ packet forwarder. Concrete examples includes OpenContrail vRouter,
+ OpenvSwitch, Cisco VTF.
+
+ 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 network
+ Virtual network routes information among the network interfaces of VM
+ instances and physical network interfaces, providing the necessary
+ connectivity.
+
+ VM
+ Virtual Machine. Virtualized computation environment that behaves like a
+ physical computer/server by modeling the computing architecture of a
+ real or hypothetical computer.
+
+ VNF
+ Virtualized Network Function. Implementation of an Network Function
+ that can be deployed on a Network Function Virtualization
+ Infrastructure (NFVI).
+
+ VNFC
+ Virtualized Network Function Component. A VNF may be composed of
+ multiple components, jointly providing the functionality of the VNF.
+
+ WAN
+ Wide Area Network.
