Definitions and abbreviations
3.1
Definitions
ETSI GS NFV-IFA 006 V2.1.1 (2016-04)
For the purposes of the present document, the terms and definitions given in ETSI GS NFV 003 [i.1] and the following
apply.
A term defined in the present document takes precedence over the definition of the same term, if any, in ETSI
GS NFV 003 [i.1].
Allocate Resource: operation that creates an instance of a virtualised resource, involving the assignment of NFVI
resources
NOTE 1: Virtualised resources can include virtualised compute resources, virtualised network resources or
virtualised storage resources.
NOTE 2: Throughout the present document the term "instantiated virtualised resource" is used to describe an
instance of a virtualised resource.
consumable virtualised resource: virtualised resource that can be requested for reservation and/or allocation
NOTE:
Virtualised resources comprise compute, network and storage.
EXAMPLE:
A volume or object based virtual storage.
infrastructure resource group: logical resource collection grouping virtual resource instances assigned to a tenant
along with Software Images
multi-tenancy: feature where physical, virtual or service resources are allocated in such a way that multiple tenants and
their computations and data are isolated from and inaccessible by each another
NOTE:
This definition has been specialized from the term "multi-tenancy" as defined in Recommendation
ITU-T Y.3500 [i.8].
resource reservation identifier: identifier that establishes the identity of an arrangement to secure usage of resources
by a consumer
NOTE:
The identifier does not identify the resources that have been reserved.
tenant: one or more NFV MANO service users sharing access to a set of physical ,virtual or service resources
NOTE 1: This definition has been specialized from the term "tenant" as defined in Recommendation
ITU-T Y.3500 [i.8].
NOTE 2: The "tenant" concept in NFV should not be confused with the "tenant" (aka "project") concept in
OpenStack. The OpenStack implementation covers a subset of the overall functionalities required by
multi-tenancy in NFV.
3.2
Abbreviations
For the purposes of the present document, the abbreviations given in ETSI GS NFV 003 [i.1] apply.
An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any,

VIM exposed interfaces
7.1
Introduction
This clause defines the interfaces exposed by the VIM towards the VNFM over the Vi-Vnfm reference point.
NOTE 1: The fact that operation parameters and information element attributes are presented in tabular form does
not preclude stage 3 designs in which these operation parameters and information element attributes are
encoded in different parts of request and response messages. For example, in a RESTful interface, parts of
them may be encoded in the URL, in the message header, in the message body or any combination
thereof.
NOTE 2: The present document version does not specify the required operations for the management of resource
groups for infrastructure tenants (e.g. creation of a resource group, etc.). The management of resource
groups is necessary to support operations where a "resourceGroupId" is carried in input and/or output
parameter of the operations. Refer to interface operations:
Allocate virtualised compute, network and storage resource operations (clauses 7.3.1.2, 7.4.1.2 and
7.5.1.2).
Virtualised Resource Quota related information elements (clauses 8.8.2.2, 8.8.3.2 and 8.8.4.2).

Software Image Management Interface
7.2.1
Description
This interface allows the VNFM to query the VIM for software images.
NOTE 1: This interface addresses software images at virtualisation container level, e.g. VM images.
NOTE 2: The interface exposure assumes (but does not mandate that) software images are stored in repositories
managed by the VIM(s) in order to minimize delays incurred on transferring such software images after
initiation of VNF lifecycle.
NOTE 3: The Query Images operation applicable on multiple images is assumed to be best effort.
7.2.2
Query Images operation
7.2.2.1
Description
This operation allows querying the information of software images in the image repository managed by the VIM.
For example, this would allow retrieving information of a selection of images previously provisioned, based on filtering
criteria using the image metadata, or to obtain URIs of images based on metadata criteria in order to be able to choose
the appropriate kind and version of image for creating new Virtualisation Container instances.

Virtualised Resources Performance Management Interface
7.7.1
Description
This interface allows providing performance management (measurement results collection and notifications) related to
virtualised resources including (not limited to) resource consumption level, e.g. vCPU power consumption, VM
memory usage oversubscription, VM disk latency, etc. It has to be noted that only types of resources that have been
catalogued and offered through right abstractions to consumer functional blocks are in scope.
Collection and reporting of performance information is controlled by a PM job that groups details of performance
collection and reporting information.
When new performance information is available, the consumer is notified using the notification
PerformanceInformationAvailableNotification (see clause 8.5.8). The details of the performance measurements are
provided using the PerformanceReport information element (see clause 8.5.5). Delivery mechanism for the performance
reports is left for later specification.
ETSI

3)

This operation will create a PM job, enabling a VNFM to specify a resource or set of resources, that the VIM is
managing, for which it wants to receive performance information. This will allow the requesting VNFM to specify its

The VNFM needs to issue a Subscribe request for PerformanceInformationAvailable notifications in order to know
when new collected performance information is available.

At the end of each reportingPeriod, the VIM will inform VNFM about availability of the performance data
collected for each completed collection period during this reportingPeriod. While the exact definition of the
types for collectionPeriod and reportingPeriod is left for further specification, it is recommended that the
reportingPeriod be equal or a multiple of the collectionPeriod. In the latter case, the performance data for the
collection periods within one reporting period would be reported together.

Information elements related to Affinity or AntiAffinity
8.4.8.1
Introduction
This clause defines information elements needed to express affinity and anti-affinity of a given virtualised resource
(i.e. a virtualised compute, storage or network resource).
Two ways of specifying affinity or anti-affinity can be distinguished: Explicit resource lists and named resource groups.
In case of an explicit resource list, the consumer manages the list of resources the actual resource is requested to be
affine or anti-affine with, and builds the list as more resources are created. In case of a named resource group, the
consumer needs to create the group first by invoking the appropriate operation to create a Compute/Storage/Network
resource affinity or anti-affinity constraints group defined in clauses 7.3.1.9, 7.4.1.6 and 7.5.1.9. Subsequently, as part
of resource creation, the consumer passes the name(s) or identifier(s) of the group(s) to the producer which manages
and builds the group of resources.
The VIM shall support both explicit resource lists and named resource groups for affinity/anti-affinity. The VNFM shall
support at least one of these options.
