Problem statement

  • Different information models and data models are being used amongst SDOs and open source communities resulting in fragmentation and complexity for implementation hence increased cost and delayed time to market
  • There are several barriers to collaboration amongst SDOs and Open Source communities.


  • To review progress since the original workshop held January 2016 at CableLabs and December 2016 at Deutsche Telekom
    • Review issues that we considered important and if we didn’t make progress, understand why
    • Address work that has been done on the issues collected from the first workshop
  • Share latest understanding on how different information models and data models are impacted by NFV or are impacting NFV
  • Identify roadblocks to progress and agree how to overcome them
  • Continue to build collaboration and refresh commitment to work together to address the problem
  • Consider whether to merge with the cross-industry Network and Service Management activity (workshop orgasnized by Deutsche Telekom earlier this week)

Workshop Inputs


Outcomes and action items

-> Status update of ETSI NFV-ISG (Mar. 14) to be discussed in a call on Mar. 14.
Peter Wörndle, Klaus Martiny
How realistic? Consider Federated Information Model(s) as evolutionary step
LingLi Deng, Robin Mersh
Collection process?
-> Initial proposal (Jan.18) to be discussed in a call on Jan.24.
Mark Cummings, Nigel Davis
  • Considered a barrier due to different language in different “domains” and more generally
  • Agreed definitions of Data Model and Information Model (e.g. RFC 3444)
  • Agreed definition of “micro-services”
  • How to collect and where applicable, align nomenclature. Likely to be ongoing iterative process
-> Initial proposal (Mar. 14) to be discussed in a call on Mar. 14.
  • YANG: Benoit Claise, William Lupton
  • TOSCA Templates: Arthur Berezin, Shitao Li
  • Papyrus UML models: Bernd Zeuner, Augie Jagau
  • Encourage ecosystem by simplifying adoption of common models and availability of tooling
  • Document the infrastructure aspects that set the context for the tooling
  • Consider how to overcome IPR barriers
John Strassner, Nigel Davis
  • Analysis of overlaps and Touch Points
  • Mapping of the models
Alex Vul, Michael Brenner
  • When is TOSCA applicable, and when is YANG applicable?
  • How do they interact with each other?
  • Converge understanding of these aspects including consideration of modeling language
John Strassner, Nigel Davis
  • Separation of concerns
  • Dependency on the Domain Listing
  • Horizontal and vertical decomposition
  • Harmonizing the semantics
  • Impact of architectures (services, software, implementation architectures, etc.), e.g. Containers
John Strassner, Nigel Davis
Klaus Martiny, Robin Mersh, Scott Mansfield, Michel Besson, Augie Jagau
  • 3GPP (SA2, SA3), IEEE (802.1, 802.3, 802.19-Ethernet), GSMA, DMTF
  • ODL, OpenStack, OIF, Open Air Interface
Klaus Martiny, Don Clarke, Mark Cummings, Deng Hui
Ensure transparency & even handedness
Klaus Martiny
Consider adding some of these issues to the problem statement for NSM
Refresh the mailing lists
-> Closed
Klaus Martiny
  • Separated NSM and Information Model Lists. Potentially combine later?
  • Consult with ETSI on continuing hosting of the lists
