Do you happen to know if the patch will be also available for
folsom?<br>

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
instability in the stable version.<br>

<br>
In an Openstack deployment using Quantum, the
compute nodes access the public/external network via
the network node (as per the diagram
<a class="moz-txt-link-freetext" href="http://docs.openstack.org/trunk/openstack-network/admin/content/connectivity.html">http://docs.openstack.org/trunk/openstack-network/admin/content/connectivity.html</a>).<br>
<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
resources be a bottleneck?<br>

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

<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>
Thanks<br>
