Hi Diego et al.,

I have a series of questions about this I-D.

First off, of course, thanks for taking the time to write and submit
it!  The multiplane management and operation of the network is
definitely a necessary approach.

Let's see...

1. I know it's heavily informed by your QKD work, but can you say a
    little (here on the list, no need put it in the document yet) on
    your view of the relevance of this document to more general-purpose,
    entangled quantum networks?
2. Likewise, what about the relationship with <whisper> ITU
    </whisper>? You have cited (and probably worked on) a number of
    those QKD-specific documents; how do you see the IETF role v. the
    ITU role?
3. My _impression_ of the ITU work is that it is strongest at the
    physical layer and above the application layer, at the key
    management functionality. This leaves a big gap in the middle
    layers -- L3-4 ish, give or take.  Does that match your experience?
4. "Quantum forwarding plane" is probably the wrong name. For
    entangled networks, there really is no forwarding; the service
    provided by the network is creation of E2E entanglement to be
    consumed by applications.  That is very much a distributed process,
    nothing at all like the Internet's store-and-forward of packets.
    (Actually, I would expect this aspect to be true for multihop,
    trusted intermediate node QKD, as well.)
5. Going back to point 1, how will this architecture support the
    stages of evolution of a Quantum Internet as outlined by Wehner,
    Hanson, Elkouss (Science)?
