1. Information Modelling Workshop Overview
Michael Brenner, ClearPath Networks, ETSI NFV ISG Vice-Chairman
Klaus Martiny, Deutsche Telekom, NOC Vice-Chairman
*Hosted by CableLabs, Louisville, Colorado USA, January 13-14, 2016*

2. Motivation
The benefits we are looking for in NFV (cf. ETSI GS NFV 001):
Rapid service innovation through software based deployment and operationalization of network functions and end-end services
Improved operational efficiencies resulting from common automation and operating procedures
Reduced power usage achieved by migrating workloads and powering down unused hardware
Standardized and open interfaces between network functions and their management entities so that decoupled network elements can be provided by different players
Greater flexibility in assigning VNFs to hardware
Improved capital efficiencies compared with dedicated hardware implementations

3. Objectives for Information Modelling Workshop
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
Workshop Objectives
To seek consensus that there is a problem and that it should be addressed through industry collaboration
Do we know what the issues are: Issue 1, Issue 2, …
To foster a spirit of collaboration and commitment to work together to address the problem
To understand how different information models and data models are impacted by NFV or are impacting NFV
To reach agreement on the next steps for collaboration towards harmonization of the aspects of information models that are applicable to NFV

6. “Rules of engagement”
Assess whether “as a village” we can do better to help the NFV paradigm succeed, and if so, how.
No intent to impact any organization’s IM/DM current plans
Strive towards rough consensus on actions to undertake, even if actions may not impact every organization
Agreed actions to be confirmed during WS by an organization designated leader (have ONE pre-identified).
Take any such agreed actions back to organizations for feedback/approval

7. Proposed issues/proposals discussion flow
Alternative 1:
Discuss/clarify issues/consolidate: 2.5 hrs
Attempt to merge/group/sort the issues by merging related topics & group them by:
Issues impacting more than 2 orgs (which ones, if possible); vs exactly 2 organizations (which ones, if possible) vs Issues impacting a single a organization (which one, if possible)
Alternative 2:
Discuss/clarify issues/consolidate “low hanging fruit”: 1.5 hrs
If a limited amount of “difficult” issues remain, a ready-to-go team uses a breakout room for 1 hours to progress on consolidation
In the main room, we start discussing the process going forward & examples of how we could progress
Present/discuss results of additional “processing”: 15 min
Propose/discuss process to address issues
Lunch
Back to original agenda (agree process/next steps/timeline/PR)

8. Process to address issues
Take the issues/proposals list to process inside each organization
Identify the relationship/impact of the issue/proposal to the organization
Identify issue(s) in which organization is interested to collaborate
Clarify the business driver for working on identified issue(s)
Prioritize
Identify other organizations with whom you may be interested to collaborate to solve identified issues
Engage in discussions: create a “coalition of the willing” (per issue)
Make a realistic plan agreeable to the “coalition”(time, IPR constraints)
Provide coordinated to all organizations – see overall timeline proposal
Other?
Next significant milestone … execute on the plan

9. Examples: “low hanging fruit” for next 3-6 months
Create an industry landscape with orgs NFV-related IM/DM “touchpoints”:
Peer-to-peer impact – e.g. ONF-ETSI NFV, 3GPP-ETSI NFV
One-to-many
Many-to-many
Identify an initial small subset of terminology used for NFV-related IM/DM to be aligned across multiple orgs
Identify what “NFV CIM” means within the context of peering with another organization, before reaching to “NFV CIM” for all; when agreed peer-wise, progress on:
common terminology, methodology, joint work

10. Network Operators desired industry collaboration timeline for NFV Information Model
End of March, 2016 (Conference call, Date: TBD)
Follow up, initial statement for each organization plan
Review/align work programs and develop proposals for NFV IM collaboration
Middle of June, 2016 (Joint Workshop, Date/location: TBD)
Presentation and analysis of detailed plan from each organization
Middle of September, 2016 (Conference call, Date: TBD)
Progress update from each organization
Review/align
End of December, 2016 (Joint Workshop, Date/location: TBD)
Joint report on alignment of information model across industry including collaborative action completed by each organization
Final presentation from each organization
Discuss additional actions for 2017 and plan implementations

11. What we achieved (and it is a LOT!)
Very useful information sharing related to IM/DM affecting/affected by NFV, across organizations
Agreed on the WS problem statement regarding IM/DM industry fragmentation and collected a set of issues affecting “the ideal” IM/DM work outcome for NFV, and associated proposals to address
Shared a process for consolidating issues, with examples
Shared a process for next steps in processing issues/proposals at each organization level
Presented a potential timeline for progress reporting
Agreed to share feedback on progress at end of March:
Regarding processing the issues/proposals & proposed timeline
Agreed on messages to media/analyst
