Maybe just a request for clarification...

Unless I am misreading this, it seems to me that the intent is to
create a packaged solution for data centers that combines data plane,
control, and architecture. I think these are actually very separate
facets and should really be mostly separate tracks. I would liken this
to how IP, routing protocols, and our current data center architecture
has evolved. These were never defined together and so the dependencies
between them have always been quite minimal. This has allowed us to
completely change one part with redoing the rest of world (e.g.
IPv4->IPv6, decentralized routing to open flow,..).

It might also be nice to clarify a little more what the ultimate
output is of the WG. I assume the tangible output here would be
standardized data plane protocol(s) and control plane protocol(s).
Architecture is nice to provide a context for the protocols, but not
really something that can be standardized in itself. Every existing DC
already has an existing architecture (even before virtualization), it
is much more likely that we'd want to adapt and leverage the existing
architecture as much as possible rather than change the whole world to
accommodate NV-- which I guess is another way of saying data plane,
control plane, architecture need to be considered independently.

Hope this helps :-)
