Forwarding Path & Signaling Management discussion

Hello folks,

Here are few clarification questions and comments on the Forwarding Path & Signaling Management WT discussion material (oh, maybe it's time we start numbering these WTs :-)
http://www.ietf.org/proceedings/interim/2014/10/07/dmm/slides/slides-interim-2014-dmm-3-1.pdf


- Are we not going to support roaming? Or, even w/o roaming, I'd think there'd be inter-domain signaling, e.g., DPA and DPN belonging to two different networks.

- What is the difference between DPA and DPN? We need definitions for these terms.

- Slide 8: Is this simply showing how BGP-based solutions can be covered here? Or something else?

- What is the relationship between Slides 6-7-8? 

- What is a controller "type"?

- Should QoS really be part of this work? I think not…

- Why would DP be querying CP? 

- Slide 13: It's not immediately clear why we need these identifiers, and how they are used. Maybe there's a solution behind them, but the reader cannot get the picture.

Thanks.
