<div dir="ltr">Hello.
<div><br></div><div>I've been learning OpenStack from Havana, and as far as I know the DVR (Distributed Virtual Router) Concept has been raised since Juno.</div><div><br></div><div>I wonder whether the DVR is finally supported fully at Liberty. Furthermore, does it solve the issue related networking performance of OpenStack, especially in aspects of the traffic congestion on a Network Node?</div><div><br></div><div>In the past version of OpenStack, the external traffic, which means a traffic between a VM and a external host such as google server, should pass through a Network Node because the virtual router (OpenvSwitch) in the network node has a role for gateway of external networks. So, if the number of VMs is hugely increased the traffic also become significantly, and the congestion occurred.</div><div><br></div><div>I'd like to know the current states of the OpenStack Networking and what has been solved from the past versions from the point of view of performances.</div><div><br></div><div>Best regards</div><div><br></div><div>Kim</div><div><br></div><div><br></div></div>
