Hi all, I and Yamahata talked about Ryu at OpenStack Design Summit 2012, and there were many hot discussions there! Here are some short summaries of them. - Scalability How many VMs and how many switches does Ryu support now? To be honest, we don't have a concrete number about it. However, Ryu aims at tens thousands or higher nodes, which is difficult to be handled by the existing hardware solutions. We also plan to support distributed ryu-managers in near future. It would provide higher scalability and enable us to create virtual networks even if the underlying machines are not in the same data-center. - Integration with Quantum and Nova There were many questions about how Ryu works with OpenStack. Currently, OpenStack with Ryu has some limitations (e.g. VMs cannot use the same IP address), but the most of them comes from Nova. I hope they would be solved in the next release FolSom. In the design summit, there was a session to discuss the requirements of Quantum plugins (the summary is in http://etherpad.openstack.org/quantum-folsom). We also should support them in our plugin. - Other tunneling protocols It is possible to use other protocols for tunneling if OVS supports them. On the next day after our presentation, Cisco developers showed me a demo, which uses VXLAN for tunneling with their customized OVS. It was really cool! We plan to support protocol conversion among VLAN, GRE, MPLS, and so on. It is necessary to keep isolations when Ryu manages virtual networks and physical networks at the same time.
