Laurent, 

Since we couldn't finish the discussion online, here my comment on the list: 

You won't be surprised to hear that I'm asking also here for the smallest, simplest possible first step. To get us all on the same page, and understand the requirement better. 

So I was thinking, we actually have a good use case for this: draft-ietf-anima-prefix-management could probably do with a small knowledge plane; in its simplest case, an operator wants to know the current status of assignments across the entire network; before a node requests more address space from another node, it could ask a knowledge plane where the biggest free pools are. 

Disassembling this a bit: questions to the knowledge plane could be: 
- "which node has the biggest free address pool?"
- "what's the average / max / min usage of local pools across the network?"
- "how much address space is still available?" (not quite the same as above, I think)
- etc. 

Would that make a nice use case to understand the knowledge plane better? 

Michael
