    I think that we will have to wait and see. I do not think that the
    chances are great as it is a major change and could cause

                    In an Openstack deployment using Quantum, the

                    the network node (as per the diagram

                    <br>
                    So if I have a hundred compute nodes each running
                    hundred instances, wouldn't the link to the network
                    node choke? Also wouldnt the network node's

                Yes. At the moment the network node is the bottleneck.
                There is a patch upstream in review that will solve this
                issue:<br>

                Hopefully this will be ready in the Grizzly cycle.<br>
                <br>
                In addition to this it also provides HA for the L3 and
                DHCP agents.<br>
