ETSI ISG ENI workshop at the SDN/NFV Forum @ Layer 123 SDN NFV World Congress 2018

ETSI ISG ENI Chair, Aria’s Head of Research and ISG ENI Technical manager Outline ETSI ENI’s AI Use Cases, System Architecture and the China Telecom Led Proof of concept at SDN NFV World Congress in The Hague.

Over the last few years, Layer123’s SDN NFV World Congress has emerged as the best place to assess the mood and state of progressive thinking in telecom operations. So it was fitting that this year’s program included a progress report from the Experiential Networked Intelligence (ENI) Industry Specification Group (ISG) team developing a reference model for the use of AI in telecom operations.

NFV#23 – Quebecois Summer

2018-10-02 Posted by Diego Lopez, Chair ETSI ISG NFV 8234 Hits

I’d never been to Montreal (or Quebec) until this summer, and I had the double pleasure of visiting Montreal just before my holidays, as well as soon after them. These visits allowed me to get acquainted with Quebecois summer (surprisingly warmer than back home, in Southern Spain), several delicacies (both poutine and the amazing smoked meat, and some really good microbreweries), the crowded Montreal airport (at least on Friday evenings), and the easygoing nature of a city that makes life so smooth and work so productive.

And a productive week it was indeed. It was the first meeting after I was appointed chair of ETSI NFV for a second term, an honor I really appreciate and that I can only respond to by committing to do my best to keep ISG NFV where this extraordinary community has already brought it: at the core of the radical transformation towards the next generation of networks. And the leadership team is strengthened with the re-appointment of Joan Triay (NTT DOCOMO) as chair of the Technical Steering Committee, leaving the technical management of our extensive work program in the best possible hands.

It was also a meeting for consolidating our vision for the future, defining a common view that, with all the natural differences among the diverse organizations contributing to the NFV effort, will guide us in a new two-year term for the ISG. There was an in-depth discussion about the future of the group during one of our much-loved evening sessions, and the goals for the new term were agreed and submitted to the ETSI Director General for approval, just in time to be discussed at the September ETSI Board meeting.Group photo of participants at NFV23The initial phase, in which the basic NFV concepts and the NFV architectural framework were defined, established a firm foundation for the extensive specification work required to enable an open ecosystem for this new technology. Building on this foundation, as well as climbing a very steep learning curve, required the two first terms of the ISG, with the third that is about to be completed, focused on making the NFV promise suitable for real operations, and establishing the baseline for telecommunications and enterprise networks evolution, infrastructure deployment, service development, and management automation in a software-defined networking world.

What is more, the ISG has managed to explore and enhance the consensus mechanisms required to more rapidly define standards by fostering collaboration with SDOs and related initiatives, especially open-source communities. We have facilitated fruitful practical collaboration with these communities, and the industry in general, boosting prospects for interoperability, as demonstrated by the three successful interoperability events held to date. The ETSI NFV community intends to continue consolidating, improving and evolving the NFV foundation specifications as the key enablers of an ecosystem and strengthening the cross-industry collaborative mechanisms which will boost progress and ensure an agile response to the evolving industry needs.

Key achievements of the ZSM Interim#1 meeting: driving ZSM towards a truly service-based architecture and demonstrating the first ZSM PoC

The ZSM interim#1 meeting was hosted by Ericsson on 9-12 July, 2018 at their headquarters in Kista, Sweden, in a meeting room which was named after Hilda, the wife of Ericsson’s founder. The meeting was a good opportunity for the ZSM team to discuss additional scenarios, advance the ZSM architecture work and demonstrate the first ZSM PoC.

ZSM 2018 Interim 1

As described in great-strides-made-by-technical-brainstorming-at-zsm-3, the ZSM architecture supports the separation of management and automation into different areas of concern, i.e. management domains. At the ZSM interim#1 meeting and in follow-up conference calls, agreement was reached on the high-level architecture inside a management domain (depicted in Figure 1 below). Each domain includes functional components (FCs) that perform specific task(s) and expose one or more management services via service interface(s). Some of the services are internal services and can only be consumed by authorized functional components inside the domain. Other services can be exposed and also consumed by authorized functional components outside the domain (including those contained in the E2E service management domain and the digital storefront). The management services within the management domain are assembled into logical groups, such as domain control services, domain orchestration services, domain intelligence services and domain assurance services. The architecture is designed to enable closed-loop automation (connecting assurance and fulfillment processes) where the automated decision-making mechanisms (e.g. self-optimization and automated service assurance) can be bounded by rules and policies.
