NMRG meeting @ IM 2017

May 11th 2017
Room Milão I - 12:30 ~ 14:00

Attendees: 
- Marc-Olivier Pahl, TUM
- Joe Betes, Aerospace
- Mohamed Faten Zhani, ÉTS Montreal
- Imen Grida Benyahia, Orange
- Roberto Riggio, CREATE-NET
- Alexander Clemm, Huawei
- Atay Ozgovde, Galatasaray Univ.
- Laurent Ciavaglia, Nokia - Bell labs
- Lisandro Zambenedetti Granville, UFRGS
- (remote) Ali Hamidian, Huawei

. Laurent mentions two initial working topics, to discuss:
 - Intent-Based Networking (IBN)
 - Autonomic networking (AN)

...

. Alex
 - A position document, to put the concepts of IBN, PBNM (policy-based
   network management), and service management in perspective, is important
   to clarify these concepts and their relationship with each other

. Imen
 - What’s the requirements to realize IBN?
 - What’s the relationship with autonomic management?
 - A second outcome should be so to address these two questions too 

. Atay - Examples of IBN would be beneficial to clarify the concept

. Roberto - E.g., a taxonomy of intents

. Laurent - Take into account that the SCOPE of IBN is sensitive because 
   it can be either too broad (and people can get lost) or too narrow (which
   addresses too specific details)
. Alex - Refer to the classical data model x information model NMRG RFC as an
   example of a good outcome that put, in the past, concepts in perspective
   with each other
. Faten - Clarifications are important because different terms (possibly from
   different communities) would be map to terms that an NMRG outcome should
   define/consolidate
. Several people/Imen - The “requirements” document should include also open 
   questions and research challenges on IBN

. So far, 2 outcomes are then expected: 
 - 1 document for clarifying IBN/PBNM/Serv.Mgmt./AN
 - 1 document for IBN requirements, open questions, and research challenges

...

. Laurent/Alex/Lisandro - We need autonomics "beyond and above ANIMA” 
 - 3rd outcome, to report on the autonomics landscape

. Marc-Olivier/several - How AN relates to IoT, for example? That leads to the
 observation (Laurent) that a 4th document is important, in the future,

 addressing a study of the applicability of autonomic networking

 specifications to constrained environments.

...

Action points:
. Alex will take the first step towards the “Concepts” outcome

. Imen will take the first step towards the “Requirements” outcome

. Laurent will take the first step towards the “revised RFC 7575 7576”/“beyond
 and above ANIMA” outcome

Additional future topics to be considered in next NMRG interactions:
- Laurent - Management of virtualized infrastructures
- Roberto - Lightweight solution for the management and orchestration of
           distributed infrastructures (e.g.,MANO)
 . Imen - Orchestrators’ requirements and management functions “placement"
- Laurent - Network slicing
- Imen - Management of hybrid (virtualized and non virtualized) networks
