scope:

The present document specifies the functional architecture of an ENI System, which is a high-level decomposition of an ENI System into its major components, along with a characterization of the externally visible behaviour (e.g. as defined by a set of reference points) of the components. This includes:

• defining the functionality and behaviour of a system that satisfy the ENI Requirements (ETSI GS ENI 002 [i.40]);

• defining a functional architecture, in terms of Functional Blocks, that addresses the goals specified by the ENI Use Cases (ETSI GS ENI 001 [3]);

• defining Reference Points used by the above Functional Blocks for all communication with systems and entities that are external to the ENI System;

• proposing a progression plan towards full support of the proposed ENI System and intermediary level of compliance (e.g. support of some architecture components or a subset of the Reference Points).

The purpose of the present document is to continue the development of ETSI GS ENI 005 [i.53] (V2.1.1) to:

• define and specify APIs, Interfaces, and protocols used by ENI based on information and data models;

• specify the ENI cognition model in detail;

• enhance the description and specification of the ingestion, normalization, and output generation of data, information, and policies (imperative, declarative, and intent) in greater detail;

• enhance the description and specification of the control loops used in ENI;

• enhance the description and specification of policy management used in ENI;

• enhance the description and specification of architectural principles for interacting with other groups within and outside ETSI.
