Summary
After covering the OVS bridge interfaces in brief we showed how Neutron communicates with Open vSwitch. With OVS being the most used virtual switch in OpenStack Datacenter deployment this is important in understanding the relationship between OVS and OpenStack.
We described how Open vSwitch and Neutron are evolving to address higher performance, scaling requirements.
