Sophia Antipolis, 07 February 2024

On December 11, the third Cloud Native Roundtable was held as a special session of the 44th ETSI NFV Plenary Meeting in Tokyo Japan. This time, the roundtable mainly focuses on sharing the experience and research achievements of the Asian operators.

NFV 44 Roundtable 1

Four prominent engineers leading the commercial development of network virtualization for major Japanese operators (KDDI, Softbank, Rakuten Mobile, and NTT DOCOMO) were invited to share the current development status, challenges of the Telco cloud and expectations for future network virtualization concepts and standardization. Researchers from University of Tokyo, NTT, and China Mobile were invited to present their view on the further evolution of mobile network architecture and network virtualization technologies. Besides these, the CTO of Linux Foundation Networking was invited to this roundtable as well to give a keynote speech on open-source activities for network virtualization and how could open source and ETSI NFV can further collaborate.

Ranny Haiby, CTO of Linux Foundation Networking (LFN), gave an overview of the activities of ONAP, Nephio and ODIM, which are representative open source projects for network virtualization under the LFN umbrella. He also highlighted the importance of cooperation between these projects and standardization, and made a proposal for strengthening cooperation with ETSI NFV in the future. Ranny said that key to successful collaboration is having individuals active in both open-source projects and standardization with acknowledgement on the differences between the two. He also mentioned the importance of face-to-face collaboration and encourage more activities to be held in the future.

Release of new NFV specifications V4.5.1

2024-01-29 Posted by NFV support 11458 Hits

Sophia Antipolis, 29 January 2024

The ETSI Industry Specification Group for Network Functions Virtualization (ISG NFV) has just published its specifications of version 4.5.1 (except for NFV006, which is to be published separately). In this version, container-related functionalities have been completed (such as the support for container cluster management), and new features have been added, both in stage 2 and stage 3 (such as flexible VNF deployment, certificate management and fault management model). Version 4.5.1 is the final for NFV Release 4 and version 4.6.1 is only maintenance.

The enhancements of the architecture enable the NFV framework to support Certificate Management Function (CMF) and Intent Management (IM). Certificate Management strengthens the security of both communication between VNFs and communication between NFV-MANOs internally, and enables certificate verification in multi-vendor environment. Intent Management helps NFV-MANO to support intent based management interfaces between the NFVO and its consumers.

In addition, stage 2 version 4.5.1 specifications include support to Fault Management model to unify alarms type, interface between CIS Cluster Management (CCM) and Virtualised Infrastructure Manager (VIM), and the new Flexible VNF deployment feature.

The stage 3 specifications related to the support for containerized workloads have been enhanced e.g.: to strengthen security and to provide guidance via MANO procedures. The new stage 3 CIS Cluster Management (CCM) specification, enhancement of existing interfaces to support Certificate Management, and new Flexible VNF deployment feature are part of this version.

NFV#43 transitions to Release 6 studies and Release 5 normative work

ETSI ISG NFV Chair, Yoshihiro Nakajima, gave the opening speech and pointed out that Asia-Pacific is pioneering the 5G SA global implementation, with NFV telco cloud providing the much-needed foundation for such deployments. Therefore, this roundtable was targeted to hear the learnings of the operators within this area and their thoughts on the NFV future evolution for supporting 5G-Advanced and beyond business. He also highlighted the main characteristics of the NFV community, being built on openness and collaboration; characteristics that were fundamental pillars for its 10-years successful journey to create globally adopted standards in the industry.

NFV#42 plenary with key focus on rejuvenating ETSI-NFV activities for the future

2023-06-27 Posted by Rajavarma Bhyrraju, WG IFA Vice Chair 12417 Hits

Meeting at ETSI headquarters of Sophia Antipolis in May-June has been always wonderful with a lot happening (local festivals, fun and adventure activities) in and around Nice, Antibes, Grasse and Cannes. It can be a time to rejuvenate yourself in this perfect weather. Some of us were happy to spend the weekend due to Technical Steering Committee (TSC) workshop on 1st and 2nd of June 2023. This year as well, we were greeted with gorgeous weather and wonderful gathering of NFV delegates onsite for NFV#42 happened between 5th to 9th of June. People who couldn't travel were able to join remotely for this plenary as well continuing the hybrid meeting practices.

During the opening plenary on 5th June, Madalin Neag (part of ETSI Secretariat) presented the agenda for NFV#42 plenary meetings, working group sessions and proposal for special ISG sessions during that week. ETSI ISG NFV chair, Yoshihiro Nakajima-san presented to the ISG on the latest accomplishments of the group and introduced the background on the special ISG sessions in NFV#42 plenary meetings. The special sessions were reserved to discuss the collaboration with other SDOs and to collect new ideas on, how to efficiently steer future work in the NFV. Madalin presented the progress made since NFV#41. The TSC manager, Ulrich Kleber then presented detailed status of Releases 4, 5 and 6, including:

- 24 normative specifications were published for edition 4.4.1 in Release-4.
- 6 informative group reports were published in Release-5.

Diego Lopez, chair of NFV’s NOC (Network Operator Council), shared this group’s views on the future of ISG, the challenges with Versioning of the specifications, view on Convergence of network models and the analysis, prioritization of new features in Release 6. The details and insights shared were appreciated and appropriate actions were noted by the ISG to follow-up.

Next step in NFV feature development published

2023-05-24 Posted by ISG NFV Leadership team 12910 Hits

When ETSI ISG NFV met in Sophia Antipolis recently for their 41st plenary meeting, it was not only collocating the 10 year anniversary celebration (see separate blog post here) with a week full of technical discussions. It was also a major step to provide the next package of specifications in NFV’s Release 4. The new package contains edition 4.4.1 documents for both stage 2 and stage 3.

In stage 2, 14 documents were updated mainly with maintenance. In addition, 2 new group specifications were published:

ETSI GS NFV-IFA 048, which adopts the State-Task design pattern to specify the NFV-MANO policy information model. The information elements in the model are transferred through policy management interfaces over NFV-MANO reference points, which enable the enforcement of policies in the framework of NFV-MANO. Stack-Task design pattern supports representing different policy expression forms and provides more flexibility and extensibility in respects to policy.

ETSI GS NFV-IFA 047, which specifies the service requirements as well as service interfaces produced by the MDAF (Management Data Analytics Function). Following the recommendations from a previous Release 4 group report ETSI GR NFV-IFA 041 on enabling autonomous management in NFV-MANO, this specification specifies a new function named MDAF (equipped with AI/ML models) and its service interfaces, which improve decision making of NFV-MANO in automation processes especially for network service management and orchestration.  

In stage 3, there were 10 updated documents. The major highlights are described below:

ETSI GS NFV-SOL 018 - Profiling specification of protocol and data model solutions for OS Container management and orchestration:

The biggest part of the updates was about Cloud-Native VNFs and Container Infrastructure management. After the big leap forward in the support of containerized workloads in the NFV framework, which the previous edition 4.3.1 represented, the recently published 4.4.1 edition has brought additional support and consolidation of the feature.

Interim face-to-face meeting of ETSI NFV IFA (Interfaces and Architecture) working group in Munich

2023-05-12 Posted by ISG NFV WG IFA 12691 Hits

The weather in Munich in late April was still a bit cold, but it did not prevent the ETSI NFV’s IFA working group (WG) from gathering in an interim face-to-face meeting under the warm hospitality of DOCOMO Euro-Labs. IFA WG is mainly responsible for delivering NFV stage 2 related specifications, including NFV architecture, interfaces and information model design, as well as informative work study on any new architectural related use cases exploring the evolution of NFV. This WG’s mission makes IFA an important WG within the ISG NFV, with always constant workload and substantial high-intense discussions. 

The proposal for an interim IFA meeting was made during the NFV#41 plenary meeting, held in March this year, in order to address the amount of work to be completed by the WG by this summer. The proposal was endorsed by the Technical Steering Committee (TSC) and the ISG, as a whole. The interim WG meeting targeted to speed up the progress of active work items which are part of Release 4 and 5 and promote many of the work items to catch up with the upcoming summer release drop delivery timeline. 

This interim meeting restarted the practice of past interim WG F2F meetings in ETSI NFV after 3 years’ hiatus due to the worldwide epidemic of COVID-19. The last memories of these interim meetings were from 2019, when IFA and SOL WGs jointly held interim meetings in Munich (same city, but with different hosting company) in March 2019. We would like to thank DOCOMO Euro-Labs for kindly hosting the interim WG meeting this time. Seven WG colleagues participated to the meeting on site and a dozen of other colleagues attended remotely.

First deliverable for NFV Release 5 feature: applying SBA design style to NFV-MANO

2022-12-23 Posted by Janusz Pieczerak, ISG NFV Vice-Chair 14440 Hits

The ETSI Industry Specification Group (ISG) NFV has published the report ETSI GR NFV-IFA 039 titled " Report on Service Based Architecture (SBA) design ". This document is the first deliverable for the NFV Release 5 feature on “Service based architecture”.

Service based architecture (SBA) is an architectural style that places emphasis on the services provided by individual architectural components. Services are accessible over service interfaces, and are offered by service producers and consumed by service consumers. ETSI GR NFV-IFA 039 provides a feasibility study on the application of SBA design style to the NFV-MANO architectural framework specified in ETSI GS NFV 006. This includes - but is not limited to - studying aspects such as making interfaces independent from reference points, identifying new functionality related to NFV services like service registration or applying generalization for some services.

NFV#38, a post-COVID19 pandemic reunion

2022-06-10 Posted by Haitao XIA, NFV IFA Chair 13366 Hits

The COVID-19 pandemic stopped ETSI NFV Industry Specification Group (ISG) face-to-face meetings for more than two years. As a result, the ISG blog posts for the plenary sessions were interrupted as well. Although people have been used to regarding online meetings as normal in the past two years, it is time now to call people back to face-to-face meetings with the gradual relaxation of epidemic prevention policies in many countries.

This time, the ETSI ISG NFV met again at NFV#38 from May 30th to June 3rd 2022, in Sophia Antipolis, France. The meeting took a hybrid format, ETSI headquarters hosted 23 delegates from Europe, Asia and North America. Many other delegates participated in the meeting remotely due to their inability to travel. This is the first time that ETSI NFV has returned to a face-to-face meeting after the COVID-19 pandemic since 2020.

What happened at the NFV Evolution virtual event?

2021-05-12 Posted by Bruno Chatras, ETSI NFV Chair 15508 Hits

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.

ETSI NFV Release 3: update on protocols and data model specification outcomes

2021-01-21 Posted by Joan Triay, ETSI NFV Technical Manager and Zarrar Yousaf, ETSI NFV SOL working group Chair 18278 Hits

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.

OS container object model and management interfaces: The first set of Cloud-Native VNF orchestration specifications

2020-11-10 Posted by Jörg Aelken, Rapporteur of ETSI GS NFV-IFA 040 21552 Hits

The ETSI Industry Specification Group (ISG) NFV has published the initial release of ETSI GS NFV-IFA 040 titled "Requirements for service interfaces and object model for OS container management and orchestration specification". This document is the first normative specification delivered for the NFV Release 4 feature on “Cloud-native VNFs and Container Infrastructure management”. The specification propagates the recommendations from the study in ETSI GR NFV-IFA 029 and formally specifies the new functions required for the management and orchestration of OS containers, the Container Infrastructure Service Management (CISM) and the Container Image Registry (CIR). The CISM is responsible for maintaining the containerized workloads while the CIR is responsible for storing and maintaining information of OS container software images.NFV release 4 FEAT 17 blogpost

To enable a consistent and generic system for the management of containerized VNFs, ETSI GS NFV-IFA 040 specifies an abstract NFV object model for OS container management and orchestration, including their relationship to the core information models of NFV-MANO. The abstract NFV objects are also expected to be used in specifications profiling APIs of de-facto standard solutions, to map the abstract NFV objects to objects of the specific de-facto standard solution. One of the introduced abstract NFV objects is the Managed Container Infrastructure Object (MCIO), an object managed and exposed by the CISM, characterized by the desired and actual state of a containerized workload. Managed objects from Kubernetes® such as Deployment or Service are examples which map to an MCIO. Another new NFV object is the Managed Container Infrastructure Object Package (MCIOP), a hierarchical aggregate of information objects including declarative descriptors and configuration files for one or multiple MCIOs. Helm charts as specified by CNCF® are an example which maps to an MCIOP.

Insights on API conformance testing for NFV-MANO

2020-11-03 Posted by Pierre Lynch, NFV TST WG Chair and Rapporteur of TST010 18803 Hits

ETSI GS NFV-TST 010 (TST010) is a published API conformance testing specification for NFV Management and Orchestration (NFV-MANO) APIs. Specifically, it contains conformance tests for the APIs used on the following reference points:

  • Os-Ma-Nfvo, defined by ETSI GS NFV-SOL 005 (SOL005)
  • Ve-Vnfm, defined by ETSI GS NFV-SOL 002 (SOL002)
  • Or-Vnfm, defined by ETSI GS NFV-SOL 003 (SOL003)

The latest released version of TST010 is Version 2.6.1 (available from the ETSI website), which means that it supports the corresponding 2.6.1 versions of the above SOL documents (i.e. SOL02, SOL003 and SOL005). Version 2.4.1 is also available, and it similarly corresponds to the 2.4.1 versions of the SOL documents. This will always be the case going forward as well: the TST010 version will always match the corresponding version of the SOL documents specifying the reference points being tested.

New release: Data models for resource templates to foster interoperability between VIMs and NFVOs/VNFMs

2020-08-19 Posted by Hiroshi Dempo, ETSI GS NFV-SOL 014 rapporteur, NEC 17855 Hits

The ETSI NFV Industry Specification Group (ISG) has completed the initial release of ETSI GS NFV-SOL 014 titled "YAML data model specification for descriptor-based virtualised resource management". The specification focuses on a set of YAML-based data models used between NFVO and VIM (Or-Vi reference point), and also between VNFM and VIM (Vi-Vnfm reference point) for exchanging information on virtualised resources and their management. The work item and resulting document addresses specification gaps in the area of virtualised resource management and aim at enhancing the integration and interoperability of VNFM and NFVO with VIM solutions.

In the ETSI NFV specifications, interfaces and information models for the Or-Vi and Vi-Vnfm reference points have been specified in ETSI GS NFV-IFA 005 and ETSI GS NFV-IFA 006 respectively. Based on those specifications, the objective of ETSI GS NFV-SOL 014 is to define a set of YAML-based data models for representing information exchanged over these reference points as input and outputs to perform virtualised resource management. The descriptor-based virtualised resource management assumes a type of VIM which supports templates declaring parameters, requirements, lifecycle and composition of sets of virtualised resources.

End-To-End Management and Orchestration procedures: The ultimate step towards interoperability (Publication of SOL016 – MANO Stage 3 procedures)

2020-08-19 Posted by Rajavarma Bhyrraju, WG IFA Vice Chair 23257 Hits

Following intense technical work, ETSI NFV has just released ETSI GS NFV-SOL 016, the first stage 3 specification of NFV-MANO procedures in NFV Release 2 addressing interactions across several NFV-MANO functional blocks and/or interfaces. This specification builds on the ETSI NFV-MANO API specifications ETSI GS NFV-SOL 005, ETSI GS NFV-SOL 003 and ETSI GS NFV-SOL 002 which have defined the mandatory and optional operations and data attributes per individual NFV-MANO interface. As these specifications are focusing on individual interfaces, it is left up to the operator or the integrator to stitch together the information across different NFV-MANO interfaces to realize the NFV-MANO procedures involving interactions across several NFV-MANO functional blocks and/or interfaces, also referred to as end-to-end procedures. This might lead to various interpretations of how the end-to-end NFV-MANO procedures should work. ETSI GS NFV-SOL 016 defines procedures for selected key NFV-MANO procedures with the target to improve interoperability end-to-end.

Steady progress on Release 3 and Release 4 work

2020-03-16 Posted by Joan Triay (ISG NFV Technical Manager, DOCOMO Euro-Labs) 19270 Hits

The ETSI NFV community met for its twenty ninth plenary meeting (NFV#29) from 17 to 21 February at the Home of NFV, ETSI Headquarters, in Sophia-Antipolis, France. This time, the plenary meeting took place amidst the unfortunate situation, the Coronavirus outbreak that has hit so many countries and seriously impacted standardization work, and life in general almost worldwide. Consequently, some of our delegates were not able to travel and attend the meeting physically. Our best wishes to all of you all around the world who have been impacted by the outbreak, "wishing you a good and quick recovery".

Addressing the impact of this outbreak on the handling of the plenary meeting, ETSI provided outstanding support, as usual, by enabling remote access for participants that could not travel. Furthermore, the ISG and working group officials made a very good job of adapting the schedule and working procedures to facilitate the active participation and contributions of the remote delegates. As for those of us that had the opportunity to attend the plenary physically, ETSI had provided a very useful new facility: the delegates participating F2F could check-in for the first time by scanning their meeting QR code using a check-in station in the ETSI lobby. check in

All in all, despite the circumstances, the plenary meeting was once again a success. All working groups made steady progress in most of the work items that are currently being developed as part of the Releases 3 and 4.
