The ENI#28 meeting was online and took place on 11-14 December 2023.

• 25 ISG members present.
• 122 documents were handled and more may come in with some email approval.

The ETSI ENI Industry Specification Group was created in February 2017, today members come from operators, vendors and research institutes all over the world.

The meeting was productive and achieved progress. A deliverable ENI 035 was published during ENI#28, early Release 4, four deliverables were agreed as stable, two more are expected to be stable in January 2024:

• GR ENI 035 Categorization or AI for IP networks was published 14th December 2023 as Release 4.

With the publication of the report (ETSI GR ENI 035) specifically defining the evaluation criteria for the determination of the Autonomicity level in the domain of the IP network, it has been possible to obtain measurable criteria to score actual benchmarks. The work is foreseen to be expanded to other domains in the coming year, possibly involving domains like Datacentre.

• GR ENI 010 Evaluation of categories for AI application to Networks was declared stable as release 4.
• GR ENI 017 Overview of Prominent Control Loop Architectures was declared stable as release 4.
• GS ENI 030 Transformer Architecture for Policy Translation was declared stable as release 4.
• GR ENI 031 Construction and application of fault maintenance network knowledge graphs was declared stable as release 4.
• GR ENI 015 Processing and Management of Intent Policy is expected to be stable in early 2024.
• GR ENI 032 In-situ Flow Information Telemetry (IFIT) Deployment Scenarios is expected to be stable in early 2024.

ETSI ISG ENI Release 3 is published

Proof of Concepts

A status report of PoC (#17) on Intelligent Satellite-Terrestrial Integration Network Architecture, This PoC will use AI resource management to determining the feasibility of a combined network architecture, and provide a feasible design strategy for operators to automatically deploy network according to different types of business and application scenarios.

A status report of PoC (#18) on Intent-driven Operating for User-Centric Cloud-Network Convergence Services, This PoC will use AI resource management to determining the feasibility of a combined cloud resources to support users more efficiently and support the network pool of resources efficiently configuring to different types of business and application scenarios. This PoC project is expected to be completed at the March meeting.

A Status Report of PoC (#19) on Space-Ground Cooperative Network Slicing, This PoC will use AI to examine the concept of network slicing to configure and manage resources across differing types of network mobile fixed and satellite. PoC#17 & PoC#19 will be aligned by common members. This is linked to the report ENI 036.

The PoC descriptions and presentations are available on the public ETSI ENI WiKi Pages (ENI Wiki). The Wiki pages are revised with the latest reports and demos.

Futher new PoC proposals are invited according to the process outlined in ENI 006 version 2.1.1 on the ETSI portal. see ENI Wiki.

White Paper

A 3rd ENI whitepaper expressing the strategy for the future of the ENI work is approved and published authored by a team of ENI members.

The ISG is working on ENI Release 4.
