ETSI ISG F5G Green Workshop: To Build a Greener Optical Network in F5G-A and Beyond

2025-10-13 Posted by Yi Lin, ISG F5G Technical Manager 403 Hits

Green development has become a global consensus key priority to address the climate change, in which ICT plays an important role. In ETSI ISG F5G, Green Agile Optical network (GAO) has been defined as one of the six key characteristics of F5G-A.

In the week of September 15th ~ 18th 2025, the ETSI F5G F2F#23 was held in Chengdu, China, hosted by China Telecom. On 17 September 2025 during the F5G plenary meeting, a workshop on "Green Optical Network" was held. Seven experts from network operators, vendors and academia in the area of optical communication shared their visions, scenarios and technologies to enable a greener optical network.

PON Energy Saving Proof of Concept and Experiment based on Traffic Prediction using fine granular Telemetry

2025-07-07 Posted by Jian Tang (China Telecommunications), PoC leader, Rapporteur of telemetry and PON management work items 1190 Hits

Electricity costs are a major operational expense for telecom operators, making energy efficiency critical. Strategies like optimizing device power consumption and adjusting operational modes can significantly reduce energy use and expenses. In Passive Optical Networks (PONs), traffic volumes fluctuate rapidly, creating periods of low activity. Leveraging this, PON ports can transit to low-power modes during idle periods to conserve energy. Achieving this requires a real-time traffic load sensing system that dynamically adjusts the Optical Line Terminal (OLT) interface mode based on energy-saving scenarios, enabling a closed-loop mechanism for perception, control, and execution. Accurate traffic prediction is essential for effective energy savings. Traditional SNMP polling (15-minute intervals) is too slow for granular traffic forecasting. China Telecom addressed this by pioneering Technical Specifications for Access Network Telemetry, enabling rapid data collection via active reporting protocols (see ETSI GS F5G 011 V1.1.1 (2022‑11) and ETSI GS F5G 016  V1.1.1 (2023‑06). A Proof of Concept and experiments in a region have been performed. There is no customer complaint claimed when energy-saving is enabled, so services are not affected or the impact is small.

Driving the Optical Networks towards Higher Autonomous Network Levels

2025-06-24 Posted by Steven Hill, MTN Group, ETSI GR F5G 019 Rapporteur 1055 Hits

In April 2025, ETSI published a new Group Report (GR), ETSI GR F5G 019 (Fifth Generation Fixed Network (F5G); Fixed Network Autonomous Network level definition and evaluation), which was developed in the ETSI ISG F5G.

This document provides an evaluation basis for measuring the Autonomous Network levels (from L0 to L5) of a Fixed Network (including Optical Transport Network and the Access and Residential Networks) along with its components and workflows, and defines the evaluation methodology to score the level of a specific system in a Fixed Network.

ETSI F5G/OSL/TFS Joint Session: Building Intelligent End-to-End F5G-A Networks

2025-06-16 Posted by Raul Muñoz, CTTC, ISG F5G contributor 1137 Hits

In the week of May 19th ~ 23rd 2025, global industry and academic experts in the area of optical communication gathered in Castelldefels (Barcelona), Spain to discuss F5G-Advanced network architecture and future roadmap to F6G, and identify potential open-source implementation driven by TFS and OSL to develop PoCs of the F5G-Advanced architectures. The groups involved were ETSI SDG OSL (Software Development Group OpenSlice), SDG TFS (Software Development Group TeraFlowSDN) and ISG F5G. CTTC hosted all these meetings in its headquarters.

During this week, an open joint session between SDG OSL, SDG TFS and ISG F5G was held for the first time. The intelligent network management & control and the automatic service provisioning of the F5G Advanced networks, which contain multiple fixed network segments, becomes the common interests of these three groups.

At the Mobile World Congress 2025, the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) and Huawei Technologies showcased a cutting-edge Proof of Concept (PoC) focused on the development of a standards-based and open-source Network-as-a-Service (NaaS) platform. This initiative aligns with specifications from key standards organizations such as ETSI, IETF, and CAMARA, and is built upon open-source components including ETSI TeraFlowSDN (TFS) and ETSI Open Source MANO (OSM). The proposed solution highlights the capabilities of the ETSI Industrial Specification Group (ISG) Fifth Generation Fixed (F5G) Network. This demonstration introduced a set of technical Fixed 5G technology enhancements focused on end-to-end service delivery and network automation, using an immersive Augmented Reality/Virtual Reality (AR/VR) Gaming Service for Remote Players as a practical application of the F5G Advanced (F5G-A) architecture. The platform demonstrated end-to-end QoD capabilities, incorporating application-flow classification and differentiation. To support this, the setup was expanded to include a dedicated IP transport network for best-effort traffic, operating alongside the fine-grain Optical Transport Network (fgOTN), which was used for traffic requiring guaranteed Quality of Service (QoS). This allowed the system to differentiate between traffic types and manage them accordingly.

ETSI ZSM/F5G Joint Session: Starting the ISG Cooperation on Intelligent Optical Network

2024-10-03 Posted by Yi Lin, ISG F5G Technical Manager 1601 Hits

The 19th ETSI ISG F5G Plenary meeting was held in Sophia-Antipolis, France from August 27th to 30th 2024. As part of the Plenary meeting, an open session between ISG ZSM and ISG F5G was held. This is the first time these two ISGs have met together.

The ISG ZSM works on defining technical-agnostic end-to-end network and service management and operation framework and key technologies, which enables autonomous and future network. It is the goal of ISG F5G to apply the ZSM framework and its key enabling technologies, such as intent-based networking, Network Digital-Twin (NDT) and closed-loop automation, in the intelligent management and control of the F5G-A optical network.

Proof of concept "Cloud-based control of automated guided vehicles (AGV) and robots" finalized

2024-10-02 Posted by Sergii Shykin, ISG F5G Secretary (Huawei) 2938 Hits

Modern production facilities have to support on demand product customization to satisfy customer needs. One key technology to make this happen are Automated Guided Vehicles (AGVs). These are mobile transport robots, which distribute raw materials and parts on the factory shop floor and potentially among different manufacturing halls and warehouses. The navigation of the AGVs on the factory shop floor or in outdoor areas is a computationally complex task requiring significant computing resources. Cloud-based AGV navigation enables cooperation and centralized information exchange between multiple robots and AGVs.

As the number and variation of AGVs within a production facility site increases, so does the complexity of their control, for guaranteeing a seamless and orchestrated operation.

The International Telecommunication Union (ITU) together with the European Telecommunications Standards Institute – Industry Specification Group -Fifth Generation Fixed Network (ETSI ISG F5G), the Broadband Forum (BBF), and the China Communications Standards Association – Technical Committee 6 (CCSA TC6) organized the Fourth Joint ETSI ISG F5G, BBF, CCSA TC6 and ITU-T SG15 Workshop on "FTTR" (Fibre to the room), which took place 10 July 2024 from 8:00-12:00 (EDT)/14h00 to 18h00 (CEST) in Montreal, Canada.

The use case of on-premises fibre networks, such as FTTR, was firstly described in ETSI GR F5G 002 by the ISG F5G early in 2020. Since then, the related standards have been rapidly developed by several Standard Development Organisations (SDOs). The workshop intend was to offer the opportunity to continue the discussion on FTTR and other on-premises fibre networks for all the involved stakeholders, to reach a better common understanding of the use cases, the requirements, the deployment challenges, and the best practices. This workshop facilitates the development of an FTTR standard and the cooperation of multiple SDOs, as well as the system deployment by the network operators.
