We live in a connected world with the Internet at the epicenter connecting every person, every computer and every cell phone. Each device connected to the Internet requires a unique identity – the IP address. In theory, the old IP version 4 (IPv4) provides approximately 4.3 billion addresses – not even enough to connect everyone, not to mention everything. Since 2019, all the regional Internet registries (RIRs) have exhausted their address pool. Some ISPs or organizations may still have some IPv4 addresses. As the scarcity of the IPv4 address space worsens, the price continues to increase, during the past year, the price of an IPv4 address has doubled and passed 55 USD – per address.

Hello again, and sorry for not writing so frequently. A lot of things happened in these busy months!

ISG MEC have updated some key Phase 2 specifications, and it is continuously progressing on the current Phase 3 work. I can only say “kudos” to the rapporteurs and actual leaders of this tremendous amount of work (you can find more information in the recent ETSI press release, and also details in this pdfshort summary.

ENI Release 2

2021-12-15 Posted by Dr Ray Forbes, ETSI ISG ENI Chair 239 Hits

ENI focuses on improving the operator experience, adding closed-loop AI mechanisms based on context-aware, metadata-driven policies to more quickly recognize and incorporate new and changed knowledge, and hence, make actionable decisions.

ENI has specified a set of use cases and the derived requirements for a generic technology independent architecture of a network supervisory assistant system based on the ‘observe-orient-decide-act’ control loop model. This model gives recommendations to decision-making systems, such as network control and management systems, to adjust services and resources offered based on changes in user needs, environmental conditions and business goals.

Release 2 has specified enhanced use cases, requirements, system architecture, and Proof of Concept (PoC) specifications.

On 16 November ETSI ISG IPE held its 11th online Rapporteur call with about 30 participants, including delegates from EDF, Cisco, HPE, Huawei, Verizon, China Telecom attending the meeting.

Cédric Lavenu, Expert Research Engineer at EDF (Electricité de France) and Chair of the G3-PLC Alliance Technical Working Group, shared experience with the deployment of the G3-PLC technology, which is designed to natively support IPv6.

In 2011, French DSO (Distribution System Operator) Enedis started its smart grid project with IPv6-based G3-PLC (Power Line Communication) smart meters, called “Linky”. In late 2021, the Linky deployment is almost complete and consists of nearly 35 million smart meters deployed in the low voltage grid, behind one of the 740.000 medium voltage to low voltage transformer substations. This makes Enedis one of the largest IPv6 operators in the world.

A lot of time has passed since my last blog post, sorry for not reaching out to you, folks! Very busy period. Also, a lot of nice things are happening, and ISG MEC is continuously growing in membership, attracting new companies that are actively contributing to the standardization.

Our collaboration with 5GAA (now joining MEC!) is also well established with the identification of two MEC observers, Maxime Flament (CTO, 5GAA) and Luca Boni (Stellantis) who are acting as 5GAA representatives in MEC. The collaboration with Akraino is now also moving forward with the guidance of Jane Shen (Mavenir, Akraino TSC member and ETSI MEC Technical Expert) and Oleg Berzin (Equinix, Akraino TSC Co-Chair and PCEI PTL). Finally, we’ve recently held the 2021 edition of the MEC Hackathon (see results here, published as part of our renewed MEC Wiki page, https://mecwiki.etsi.org/).The MEC Sandbox is continuously updated with new functionalities, also used for the MEC Hackathon.

ETSI Industry Specification Group (ISG) IPv6 Enhanced innovation (IPE) had its 4th plenary on 26 October. More than 40 members, participants and guests of ISG IPE registered for the plenary and the workshop.

The plenary began with the IPv6 workshop. Our distinguished guests, Mr. Satyen Gupta (India IPv6 Forum), Mr. Arnaud Braud (Orange France) and ISG IPE participant Tahar Schaa (Neuland@Homeland) shared their experience in IPv6 deployment and the impact of regulator policy for IPv6.

  • Mr. Gupta gave the talk entitled “Convergence of 5G, IoT and IPv6-Capacity Building for New Internet IPv6 Root Server”. The importance of IPv6 as a key component of the new Internet and some IPv6 killer applications were presented (such as broadband home, cloud computing, IoT, etc.). Then Mr. Gupta further introduced the government initiatives and IPv6’s economic value in India. The fast IPv6 adoption by ISPs like Reliance JIO has made India among the top IPv6 deployment countries, representing an example of how govern IPv6 policies and support lead to excellent results.
  • Mr. Braud presented GAIA-X. It concerns EU’s digital sovereignty and data sovereignty. Currently, EU only has 4% of the cloud platform business and the fragility of international supply chains shows the importance of GAIX-X as an EU-wide federation. IPv6 is fundamental to guarantee digital and data sovereignty in a cloud system.
  • Mr. Schaa emphasized the importance of digital sovereignty for Germany and IPv6 in the public administration of Germany. For Germany, IPv6 is more than a technical issue – it forces the government to think beyond the organizations. IPv6 also leads to new fields of action in the standardization of IT networks for regulatory authorities as well as politics. IPv6 only for internal network is the target, with IPv4 offered only for end users not able to access the government Services using IPv6.

ENI#19 meeting has taken place from 6 to 9 September 2021 and has been performed online because many countries were still affected by travel restrictions or delegates were not allowed to travel. In terms of most relevant figures that denote the heavy work carried out during the meeting, it should be taken into account that:

  • 25 ISG members were present, and
  • 96 documents were handled.

Let’s remind that the Industry Specification Group (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 key specifications and demonstrate Proofs of Concepts (PoCs).

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

Highlights of the meeting

The meeting was productive and progress was achieved in different areas. Deliverable GR ENI 012 on “Reactive In-situ Flow Information Telemetry” was reviewed and declared as stable and it will now proceed to ISG review and approval. It was also decided to re-open the Work Items for the Use cases GS ENI 001 V3.2.1 in release 3 as well as Requirements GS ENI 002 V3.2.1 in Release 3.

GS ENI 005 V2.1.1 on “System Architecture” (Release 2) has completed the Remote Consensus and will be published soon.

The Terminology report GR ENI 004 V2.2.1 is in Remote Consensus until 29 September 2021, after which it is expected to be ratified and published.

An open area where all stable drafts and previously published deliverables are available, was approved.

The webinar ‘IPv6 Enhanced Innovation: the IPv6-Only Future in the 5G, IoT & Cloud Era’ was held by ETSI on September 13th. Experts from government institutions, operators, manufacturers and research institutes, shared their vision and the progress made to date within ETSI IPE (IPv6 Enhanced innovation).

Approved by ETSI in October 2020, ISG (Industry Specification Group) IPE, as a follow-up of the ETSI ISG IP6, with the prime goal at producing best practices to promote global IPv6 adoption, reference e2e architecture including emerging business scenarios and recommendations to accelerate global IPv6 adoption. Starting with 9 reports, IPE has already published its first report on the IPv6 Gap Analysis involving more than ten stakeholders, pointing out the usability of IPv6 in all  scenarios and the need to continue the IPv6 Enhanced innovation addressing the features of ubiquitous connectivity, ultra-high bandwidth, automation, low latency, deterministic quality and security. 

Zero-touch network and service automation are essential to unleash the business potential of 5G and beyond. The ultimate automation target is a largely autonomous operation driven by high-level policies and rules, enabling self-configuration, self-monitoring, self-healing and self-optimization – without further human intervention. 

Automation is not only about technology; it also requires changes in the mindset of people. Trust is a major barrier to adoption and striving to build it requires a continuous learning process. As more automation processes are deployed and operate safely and efficiently, human trust will increase and the requirement for a level of supervision/intervention will diminish. Having native security (e.g. an adaptive secured framework, access control, trustworthiness, data protection) can help to establish confidence and instill trust as the automated processes deliver the intended business outcomes.

The threat surface in the ZSM environment is extensive, firstly due to the openness of the ZSM framework. The framework is modular, extensible and service-based and expands across multiple domains. Its interfaces are open and offer model-driven services. Protecting the interfaces and the management services within and across the domains is essential to ensure the trustworthiness of the ZSM framework. 

In addition, the ZSM services can be produced and consumed by new players coming from diverse industries (e.g. government, vehicle industry, energy, transport, etc.). Each player may require or support different trust levels according to its own deployment/execution environments, security policies and regulations. This variety demands flexible and adaptive security control.  

On July 12, ETSI ISG IPE held its 3rd online plenary. Close to 40 participants, including delegates from Cisco, Huawei, Verizon, China Telecom, ARCEP (France), Ofcom (UK), registered for the meeting.

During the Workshop ok IPv6 policy, ARCEP, Ofcom, Verizon and China Telecom introduced the latest IPv6 policies of France, UK, USA and China separately:

The ETSI ZSM end-to-end network slicing specification has been released.

Network slicing is expected to become a fundamental enabler for value generation: a $300 billion global revenue opportunity by 2025, according to the GSMA.
It has been designed to support a broad variety of use cases (including the unknown) with extreme requirements, providing tailored network capabilities for each individual service. But building a network that supports tens of thousands of individual slices – all of which can be created and set up, operated, scaled, assured to meet each slice’s service-level agreement (SLA), and torn down at a moment’s notice – presents several challenges.

The accelerated worldwide deployment of 5G networks poses a significant challenge to the way networks and services are created, orchestrated and managed. Full end-to-end automation becomes crucial for the delivery, dynamic adaptation and continuous assurance of the highly diverse services – each with its own broad range of requirements – while still ensuring economic sustainability. In addition, the network’s performance, coverage and capacity should be constantly assured to satisfy the requirements of the active services.

The ENI#18 meeting was online only as many countries were affected by travel restrictions or delegates not allowed to travel. It took place at 7-10 June 2021.

  • 26 ISG members all of which were present.
  • Operators: Telefonica, China Telecom, China Mobile, China Unicom, NTT, Deutsche Telekom, and Portugal Telecom.
  • 115 documents were handled.

Last March 2021, I’ve started my new journey in ETSI MEC, taking over the Chair position from my friend Alex Reznik (HPE). Sure, of course I’m not a “beginner” in this group (as most of you who know me can appreciate that I’m there in the MEC Leadership Team since the beginning of the Phase 1!). Nonetheless, given the great work done together in these amazing years in collaboration with all MEC stakeholders, I’m grateful of the trust of many companies who elected me and expressed their warm support in my new role.

Welcome to the ISG “IPv6 Enhanced innovation” (IPE) blog, keeping you updated on IPv6 enhanced innovation work ongoing at ETSI.

The ISG IPE Kick-off meeting took place in January 2021 with the creation of 5 initial Work Items and the appointment of a leadership team.

NFV blog052021

A virtual event on NFV Evolution organized by ETSI in partnership with Telecom TV and sponsored by Huawei was held from 19 to 21 April 2021.  The objective of the event was for the ETSI NFV Industry Specification Group (ISG) to get feedback from the industry on implementation experience with the ISG’s specifications and on future topics to be addressed in next specification releases. The event was also an opportunity for the participants to get updated on ETSI NFV’s activities, deliverables and future plans, as well as on the progress made in open source communities with regards to the convergence with the ISG’s standards. The event was held in parallel with the 34th meeting of the ISG. The choice was not accidental as this was the meeting where the ISG launched the process for collecting proposals from its members and participants on the features to be addressed within the scope of its next specification release (NFV Release 5).

The event programme featured six original presentations selected from the responses received to an open call, addressing deployment experience, new use cases and technical requirements:

  • Mr. Yuya Kuno, NTT DOCOMO, presented DOCOMO’s experience in developing and operating NFV and future expansion.
  • Mr. Pierre Lynch, Keysight Technologies and Ms. Silvia Almagia, ETSI CTI Technical Expert jointly presented “Measuring NFV Evolution: ETSI NFV Plugtests”.
  • Mr. Borja Nogales, Universidad Carlos III de Madrid, presented “An NFV system to support service provisioning on UAV platforms: a walkthrough on implementation experience and standardization challenges”.
  • Dr. Lingli Deng, China Mobile, presented “From Orchestration Towards Automation”
  • Dr. Haopeng Zhu, Huawei Technologies Co., presented “Towards the future of NFV: Edge-native, Containerization, Networking-NFV convergence”.
  • Mr. Gianpietro Lavado, Whitestack, presented about the advances in deployment of standardized NFV Orchestration through ETSI OSM.

The ENI#17 meeting on 8-11 March 2021 was “online only” due to travel restrictions or delegates not allowed to travel.

  • 26 were present, 29 were registered,
  • Operators were present from: China Telecom, China Mobile, TIM, Deutsche Telekom, and Portugal Telecom, Also, NTT, Telefonica & Vodafone (messaging the Chair),
  • 121 documents were handled.

The meeting was very productive and achieved significant progress. The meeting progressed the work-items to stable output on the deliverables Draft report ENI 009 on Data Processing mechanisms planned to be approved at the end of March 2021. Report ENI 008 Intent aware architecture is in publication, the Group Report on the evaluation of categories report ENI 010 is published as v1.1.1 describing measures of automation of the Classes published in 2019 in report ENI 007 v1.1.1.

An open area is approved, for all stable drafts and previously published deliverables are available.

Last week I transitioned the position of Chair of ETSI MEC over to Dario Sabella from Intel.   Having spent four amazing years serving as the Chair of this group, I am happy to see it in such good hands.   For years Dario has been a significant contributor and an enthusiastic advocate of our work.  He’s been the driving force behind many of our Hackathons.  Moreover, Intel’s support and commitment for the group is a strong signal of our importance.  The best days for MEC are in the future and this is where all of us should look.  Still, leaving a position such as this, one does tend to reflect on one’s years of tenure and so for my last blog as Chair I am going to do just that. 

2020 turned out to be an unexpected year, with the COVID19 pandemic adversely impacting the “normal” day-to-day lives of humans across the globe. However, even during this turn of events and unforeseen testing times, communication networks demonstrated their efficacy in keeping people and businesses connected. More concretely, Network Functions Virtualisation (NFV) proved its feasibility by enabling the operators to gracefully manage high demand for network connectivity.

NFV blog evolution new vision imageUndaunted by this situation, the technical experts at the ETSI ISG NFV continued to work tirelessly developing and delivering specifications that help get and keep “everyone/everything connected”. And the hard work paid off as ETSI ISG NFV delivered during the second half of 2020 new and updated "protocols and data model" (stage 3) specifications incorporating NFV Release 3 features.

The experts in the Solutions (SOL) working group completed stage 3 work on a subset of the NFV Release 3 features. One of the first features that was already finalised in 2019 was "Management of NFV-MANO" (FEAT11) with the release of ETSI GS NFV-SOL 009 V3.3.1. This document specifies a set of RESTful protocols and APIs that can be used to manage different aspects regarding configuration, performance, fault and logging of entities implementing specified NFV-MANO functional blocks. The defined APIs leveraged the same RESTful principles used for NFV-MANO APIs in Release 2, i.e., the ones used for managing VNF instances, NS instances and on-boarding VNF Packages, NSDs and other artefacts.

New outcomes on the development of NFV-MANO APIs continued in 2020 with the release of ETSI GS NFV-SOL 011 V3.3.1, which specifies NFV-MANO APIs related to management across "NFV-MANO administrative domains" (FEAT08). These APIs are produced by the NFVO and allow different administrative domains to communicate over the Or-Or reference point to help coordinate the management of NS instances deployed on their respective administrative domains. The Or-Or reference point is set in between NFVO instances placed on different administrative domains, as specified in ETSI GS NFV-IFA 030. For instance, the APIs of ETSI GS NFV-SOL 011 enable reusing an NS instance deployed on a domain A and nest it into another NS instance deployed on a domain B. Due to the functional similarities with existing capabilities offered by the NFVO to other systems such as OSS/BSS, most of the APIs are identical or based on those specified in ETSI GS NFV-SOL 005.

The release of new API specification documents was completed in 2020 by the ETSI GS NFV-SOL 012 V3.4.1 "NFV; Protocol and Data Models; RESTful protocols specification for the Policy Management Interface". As its title hints, the document specifies a new NFV-MANO API based on RESTful principles that can be used for setting up a "Policy management framework" (FEAT07). The API, produced by the NFV-MANO functional blocks, offers the much needed management capabilities by the network operators to be able to transfer, update, delete, activate, de-activate policies, and subscribe to and get notifications related to policy management. Note that the specification of the data models and formats of the policy content is not within the scope of this document. Information and data modelling work on policy content is under development as part of the Release 4.
