It is effectively a Controller which can control Open vSwitch instances on the host, in addition to being able to control other devices speaking OpenFlow (e.g. switches which support OpenFlow). Ryu allows you to write applications on top of it as well. A simple application included is a simple L2 learning switch. There is also integration with OpenStack Networking (the project formerly known as Quantum) via a plugin.

I'm wondering if others have seen this issue on Fedora? I have not opened a bug on this yet, but can do that soon. I suspect the OpenStack Networking gerrit review listed below may make this work again, as it uses veth ports instead of OVS patch-ports to connect OVS bridges:

Hi, Kyle and Robyn. I'm a core developer of Ryu.
Although I don't know how this conversation has started and
I'm not sure what info is desired, let me supplement.

This figures depicts what Ryu can achieve with Openstack. As OVS supports
vxlan now, Ryu can easily use vxlan instead of gre.


Ryu Fedora package is available at
http://sourceforge.net/projects/ryu/files/Packages/Fedora/

So far I've requested package review for Ryu package, but not yet make it
into Fedora package yet. Its status is FE-NEEDSPONSOR.
https://bugzilla.redhat.com/show_bug.cgi?id=909674
If necessary, I'm willing to update the package and refresh the review process.

thanks,
