1 Scope
The present document captures the requirements of how intelligence is applied to the network in different scenarios to
improve operators' experience of service provision and network operation as well as how intelligence enables dynamic
autonomous behaviour and adaptive policy driven operation in a changing context. The requirements documented in
this specification are intended to be used during the architecture design work.

5 Service and network requirements
5.1 Overview
The requirements in this clause are addressed from service and network point of view and are derived directly from the
related use cases.
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 support new requirements.
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]) or the LSO RA (from MEF [i.5]) are
different types of orchestration and management systems.
ETSI

8 ETSI GS ENI 002 V1.1.1 (2018-04)
[SOM.3] The ENI framework should not directly manage, control or orchestrate physical or virtual entities, either at the
infrastructure or services level.
NOTE 2: ENI framework may interact with the Orchestration, 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
