I think that the interaction between address management entity and network element needs to be defined, it is a kind of protocol, if my understanding is right.

Hi Benoit,
Thanks for reply. This is a good question to help the group make the goal clearer. Chongfeng and Rakesh, please correct me if I misunderstood: 
1.      From the discussion on the list, we can see that Chongfeng answered this by referring to the data model draft.  
2.      However, the framework figure in Rakesh’s draft show a more broader scope including APIs. 
3.      Protocol? So far no new protocol or extensions have been raised. Or at least this is my understanding. J
To get aligned we will discuss this topic at the upcoming online meeting.

Hi Liushucheng,
Hi Benoit and all,
Thanks for your guidance. After offline discussions among all the proponents, we changed the BoF to non-WG forming in the wiki.
We also added the purpose of the BoF in the description:
The purpose of the BoF is to gather a common set of requirements from a larger set of operators and, if needed, possible protocol work milestones and scope.
Protocol work?  Which protocol?  Can you expand on what is needed?
I thought the work was about interfaces.
[Will] Thanks for the comments. As answered by Rakesh and Chongfeng, currently only interfaces are considered.
OK, to make sure we speak the same language, what do you call an interface in this context?
    - A protocol between A and B (with some negotiation, for example)? 
    - A data model? has been mentioned
    - An API?
    - etc.

Regards, Benoit
