Hi,

Thanks for the quick and elaborate response. There are still some confusions, 
it would be nice if you could clarify them.

I have been looking at the code in "/opt/stack/quantum/quantum/plugins/ryu" 
directory after devstack's installation. I have also been throught the quantum 
admin guide (and thought the best way to learn would be to look at some code 
and ask questions :) )

> nova/quantum tells necessary information to ryu via REST API.

I am still unclear on how the REST API is invoked by the nova-client. Because 
when I look at the ryu_quantum_plugin.py, it seems it is using OFPClient 
defined in client.py which (seems to me) to be passing create/delete network 
calls to the REST server. Can you please elabroate a bit more?

I appreciate the effort you are putting into this project.

Thanks!
