Hi Yoshisato, If you are trying to enable the use of OpenStack with a new network switching technology, then yes, developing a Quantum plugin is the right way to go. It may be possible to leverage work done by others writing similar plugins though. Since our developer documentation as-of-yet non-existent, I whipped up a quick wiki page with some advice on developing a plugin: http://wiki.openstack.org/QuantumDevelopment . Others should feel free to expand on this page. Also, just to clarify one thing though: Quantum is actually a separate codebase + runtime process from Nova, so you shouldn't need to modify Nova itself. Q2) Are there any open-source codes of quantum plugin for openflow ? I doubt that there will be one canonical openflow plugin for Quantum, as OpenFlow itself is really just a protocol to talk to a (virtual or physical) switch's forwarding table. There are many different ways to build a Quantum plugin that uses OpenFlow, each of which make different trade-offs in terms of scalability, fault-tolerance, complexity, feature-richness, etc. You can probably start out by taking a look at some of the existing plugins and seeing what ideas you can borrow with respect to your own implementation. Feel free to send email to the netstack list if you have more detailed questions.

Re: [Openstack] OpenStack and OpenFlow
Hello Michael and Yoshisato, Thanks for introducing our presentation, the slides can be downloaded from here: http://wiki.openstack.org/NetstackEssexSummit We have been developping Quantum plugin for our OpenFlow controller, trema ( http://trema.github.com/trema/ http://trema.github.com/trema/ ), and commercial OFC( http://www.necam.com/PFlow/ http://www.necam.com/PFlow/). By using the plugin, you can control OpenFlow-based Open vSwitch and hardware switch. Absolutely we will open-source our Quantum plugin, we are planning it by the end of this year.

Re: [Openstack] OpenStack and OpenFlow
There is an openVswitch driver for quantum right now, and i believe Nicira has a proprietary driver available as well, based on OpenFlow. there is a netstack group taht would be a good place to get more involved if you wanted to be involved with developing a quantum driver: https://launchpad.net/~netstack - joe On Oct 29, 2011, at 9:07 AM, Michael J Fork mjf...@us.ibm.com wrote: At the OpenStack conference in Boston, Su-hun Yun of NEC participated in the Networking Panel and talked about their OpenFlow implementation for OpenStack.
