Hey Cesar, 

First of all, I haven’t use Vyattas at all, but I noticed that there is neutron driver for that[1].  If you want to keep the current Vyattas deployment it’s fine, more likely you’ll need to install a neutron agent there. I’m not sure if you also need to populate the Neutron Database with the information that you have, I remember that we had to do something similar when I was working in our IT department. Lastly, the FWaaS code is there, if you need to improve certain area it’s always welcome.

Regards, 
Victor Morales

We are thinking about moving to OpenStack and when we focus on these Networking features, Neutron comes into play. We are currently using Vyattas for these networking features (firewall, instance isolation, spoofing control) and we would like to keep it as it is right now. Therefore, if we move to OpenStack we would like Neutron to orchestrate these Vyattas but these Vyattas would be installed/configured in an outter layer, out of OpenStack. A good comparison we find is Cinder. In Cinder you can configure your storage backend (this storage backend is an external "agent" to OpenStack) and the idea with this networking features would be the same (being able to configure in Neutron our firewall backend).

I don't know exactly what this implies, but if we are in the right direction, a new Neutron API set of methods would be needed. Do you think the OpenStack community would accept this change?

Are we right?
