ETSI

5.2 General requirements
This clause captures the requirements that are general and independent from other requirements categorized in other
specific clauses.
[GR.1] The ENI framework shall use history data, context, and decisions taken to learn, process and provide responses
to events, whether generated from devices or from management systems.
[GR.2] The ENI framework shall use context information as part of the computations that result in recommendations,
advisement, predictions, and decisions that are used to assist other network systems, e.g. orchestration and management
systems.
NOTE: As an example, MANO (from ETSI GS NFV-MAN 001 [i.4]) or the LSO RA (from MEF [i.5]) are
different types of orchestration and management systems.
[GR.3] The ENI architecture shall be flexible enough to support extensibility.
5.3 Service orchestration and management
This clause captures requirements related to the ENI framework service provisioning, e.g. how to compile the service
intent and orchestrate the service atoms and work flows, as well as automatic service on boarding.
[SOM.1] The ENI framework shall invoke policies based on models that describe and/or define traffic behaviour, such
as SLAs (e.g. past or current telemetry).
[SOM.2] The ENI framework shall support the closed loop control model when different orchestration and management
systems are used.
NOTE 1: As an example, MANO (from ETSI GS NFV-MAN 001 [i.4]) and LSO RA (from MEF [i.5]) are
different types of orchestration and management systems.
[SOM.3] The ENI framework should not directly manage, control or orchestrate physical or virtual entities, either at the
infrastructure level or service level.
NOTE 2: ENI framework may interact with the Orchestration system, EMS or OSS/BSS to influence the state of
the resources or services.
5.4 Network planning and deployment
This clause captures requirements related to network planning and deployment, e.g. how to allocate network resources
to VNFs, or automatic VNF on boarding.
NOTE 1: The network resources that can be managed are not limited to the requirements addressed in this clause.
[NPD.1] The ENI framework shall allocate and retrieve network resources, e.g. IPv4 addresses and IPv6 prefixes to end
users or service flows, in an intelligent way to improve the efficiency of resource utilization. This ENI framework
function may be implemented in a centralized and/or distributed manner, according to what is defined in ETSI
GR ENI 004 [i.3] and according to ETSI GS ENI 005 [i.9].
[NPD.2] The ENI framework shall assist the network equipment to use the resource pools that are used for resource
allocation (e.g. IP addresses), in an intelligent way in order to improve the efficiency of resource utilization.
[NPD.3] The ENI framework should dynamically and intelligently compute and manage the required network
resources, including both IPv4 and IPv6 resources as well as other resources.
[NPD.4] The ENI framework shall compute the network resources required to dynamically and intelligently deploy a
given network service efficiently.
[NPD.5] IT resources to enable network services shall be managed within the ENI framework.
NOTE 2: Similar capabilities within the data centre are outside the network scope of this phase of ENI.
[NPD.6] The ENI framework shall be capable of understanding the context that a set of devices is operating within.
ETSI

9 ETSI GS ENI 002 V2.1.1 (2019-09)
[NPD.7] The ENI framework shall be capable of performing the proper planning and deployment of resources to ensure
that applicable deployed policies are not violated.
[NPD.8] The ENI System shall identify different types of rollouts for different types of resources that lead to the
upgrade of virtualized software-based resources.
[NPD.9] The ENI System shall, in an efficient and dynamic manner, combine network slices, slice/service prioritization
and resource allocation concepts, e.g. in order to resolve resource allocation conflicts between competing network slices
deployed on top of a shared infrastructure.
5.5 Network optimization
This clause captures requirements related to network optimization, e.g. how to adjust the network configurations to
improve its efficiency and performance, as well as the user experience of the service.
[NO.1] The ENI framework shall collect and process the necessary data according to specific algorithms in order to
achieve network optimization.
NOTE: Data collection and processing algorithms for systems will be specified in the functional architecture.
[NO.2] The ENI
