New work on Reactive In-situ flow information Telemetry

The ENI#14 online meeting took place on 22-25 June 2020.

The meeting was very productive and achieved significant progress with 2nd release drafts.

An open area was approved, for all stable drafts and previously published deliverables. The meeting continued drafting within the work items for the next versions on ENI use cases, requirements and Terminology for Release 2.

  • Significant progress was made on the learning techniques and the definition of autonomy for AI in ENI 005 work-item RGS/ENI-0016.
  • The meeting progressed the work-items drafting on the deliverable of Draft GR ENI 008 on Intent Aware Network Autonomicity.
  • Draft GR ENI 009 on Data Processing mechanisms was well progressed in the aspects of data format, data sharing, data management, network telemetry and resource telemetry, etc.
  • Major progress on the evaluation of categories Draft GR ENI 010 was made discussing a five-dimensional system of quantification of the Classes published last year in GR ENI 007.
  • The Draft ES 011 work-item DGS/ENI-0021 on mapping to 3GPP and ONAP was progressed.
  • A new work item (ENI-0022) on In-situ flow information Telemetry (iFIT) Framework was started: Initial draft with skeleton was approved as WI baseline V0.0.1, Key concepts/terminology were approved.

The meeting also approved to send a Liaison Statement to 3GPP S2 & S5 to build a liaison relationship. The LS introduced ETSI Industry Specification Group ENI’s work and asked for further collaboration highlighting ENI 001, ENI 005 and ENI 011.

In Progress work of ETSI ISG ENI in Release 2

The Use Cases ENI 001, Requirements ENI 002, Terminology ENI 004 and System Architecture ENI 005 are all open for the next release and work has started on each specification. The new work items for the next release are also open and under drafting, including Intent Aware Network Autonomicity ENI 008, data mechanism ENI 009, Evaluation of categories for AI application to Networks ENI 010,  Mapping between ENI architecture and operational systems ENI 011, Reactive In-situ Flow Information Telemetry ENI 022.

As a reminder, Experiential Networked Intelligence (ENI) Release 2 specifications and reports published include the following:

Ongoing ENI Work Items

  • ENI 001: Use Cases (Release 2)
  • ENI 002: Requirements (Release 2)
  • ENI 004: General Terminology (Release 2)
  • ENI 005: System Architecture (Release 2)
  • ENI 008: Intent Aware Network Autonomicity
  • ENI 009: Definition of data processing mechanisms 
  • ENI 010: Evaluation of categories for AI application to Networks
  • ENI 011: Mapping between ENI architecture and operational systems
  • NEW! ENI 022: Reactive In-situ flow information Telemetry

All of the work-items were discussed and progressed.

Status of Proofs of Concepts

We have already completed 5 PoCs which include the following topics: Intelligent Network Slice Lifecycle Management, Elastic Network Slice Management, SHIELD, security through NFV, Enabled Network Traffic Classification and Intelligent time synchronization of network.

Ongoing PoCs comprise: Predictive Fault management of E2E Multi-domain Network Slices (PoC #4), Intelligent caching based on prediction of content popularity (PoC #6), Intent-based user experience optimization (PoC #8), Autonomous Network Slice Management for 5G Vertical Services (PoC #9), Intelligent Telecom Network Energy Optimization (PoC #10), Intelligent Energy Management of DC (PoC#11).

The PoC description, presentation and details are available on the public ETSI ENI WiKi Pages (ENI Wiki). Progress reports were accepted from PoCs 4, 5, 7, 8, 9, 10 and 11. PoCs 1, 2 and 3 are completed. Final reports were received at this meeting from PoC#5 and PoC#7.

Next steps

A drafting group was formed to work on a 2nd ENI whitepaper for the future of the ISG work, this drafting group comprised no less than 15 member organisations. Others are invited to join. This drafting group agreed on bi-weekly meetings to progress the draft.

The ISG will now focus on the next version of the work.

Note that the ISG is open to ETSI members and non-ETSI members alike. The different players in the value chain are welcome to join the ISG effort, contribute to the development of these key specifications and demonstrate Proofs of Concepts (PoCs). To join, please contact:

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 next ENI plenary meeting (ENI#15) will be hosted near London with remote access, or electronically on-line, depending on the Covid-19 situation. There may be an associated conference collocated with the meeting.
